DEAR
Shareholder,

Chairman of the Board

"We are dedicated to helping you and your financial advisor develop a family
wealth management strategy unique to you and your goals and values."

Setting financial goals is an important first step toward building wealth. At
Nuveen Investments, we believe those goals should not be considered ends in
themselves. Rather, you and your financial advisor's focus should be on
realizing your life's dreams--the things that matter most to you and how you can
make them happen--or make them better.

Through a well-crafted financial plan, you have the chance to shape future
generations--to broaden your sphere of influence--to leave your legacy.

As you develop that plan, you'll want to consider the different ways your
success can benefit others. You may find that you want to create a new set of
goals to achieve this. Working with your financial advisor, you have the ability
to make those dreams a reality--for yourself and future generations.

A Trusted Resource As you face some of the most important, lasting decisions you
and your family will make, you'll want to draw upon the support, counsel and
objectivity of a trusted advisor. That's because your financial advisor has the
expertise and access to other professionals who can help you make informed
choices--choices that affect not only your loved ones today, but those your
legacy will touch in the future.

        Your financial advisor can provide sound financial insight, an
integrated approach to your investments and can serve as a knowledgeable friend
with your family's best interest at heart.

Family Wealth Management Too often, family wealth management is thought of in
one dimension--as the stewardship of your household's financial resources. At
Nuveen Investments, we think of family wealth management as the map to help you
reach your financial, and your life's, destinations. It's a multi-faceted
strategy to plan for not just your needs, but the needs of future generations.

        We are dedicated to helping you and your financial advisor develop a
family wealth management strategy unique to you and your goals and values.

The Economic Environment You may be reading this report at the suggestion of
your financial advisor. I want to briefly report on the economic environment in
which your Nuveen investment performed.

        The end of your fund's fiscal period, February 29, 2000, was an
important day in our nation's economic life. It marked the 107th month of
continued economic expansion, the longest period of expansion in history. The
only period to rival that length was the 106-month expansion from February 1961
to December 1969, a period known best for its military conflicts, domestic
unrest and soaring inflation.

        That was then; this is now.

                                                            ANNUAL REPORT page 1

Nuveen is dedicated to providing investors access to a team of highly
experienced investment managers, each overseeing portfolios within their
specific areas of expertise. This select group of asset management firms directs
the investment activities of the Nuveen Mutual Funds. Nuveen has chosen them for
their rigorously disciplined investment approaches and their focus on consistent
long-term performance.

Drawing on decades of experience and specialized knowledge, these skilled asset
managers have earned reputations for excellence in their fields of expertise,
whether it is blue-chip growth stocks, large-cap value stocks, bonds or
international securities.

Nuveen's income-oriented funds feature portfolio management by Nuveen Investment
Advisory Services (NIAS). NIAS follows a disciplined, research-driven investment
approach to uncover income securities that combine exceptional relative value
with above-average return potential. Drawing upon 300 combined years of
investment experience, the Nuveen team of portfolio managers and research
analysts offers:

 .  A commitment to exhaustive research

 .  An active, value-oriented investment style

 .  The unmatched presence and trading leverage of a market leader.

        The vigilant inflationary watch of Federal Reserve Chairman Alan
Greenspan, the growth of the Internet and other technology-related developments
and the globalization of the economy are three reasons for continued economic
health.

        In their battle to keep inflation at bay, Greenspan's Fed raised
interest rates on February 2, 2000, and again on March 21, 2000. The latest
increase marked the fifth time the Fed has raised the federal funds rate--the
interest that banks charge each other on overnight loans--since June 1999.

        Over the short term, the inflation threat has meant increased price
fluctuations in the equity markets. Part of that is due to the fact that
investors and the various markets have been watching--and reacting to--every
announcement concerning economic statistics.

        Longer term, we believe there's still faith in the emerging paradigm,
which holds that improvements in productivity enable us to have both economic
growth and low inflation at the same time. The 1960's 106-month expansion that I
noted earlier was fueled by government spending. Today's economy has been fueled
by consumer spending and improved productivity.

        Performance Review Your fund's assets are invested in a diversified
portfolio of high-quality money market instruments that the management team
believes present minimal credit risks. I'm pleased to report that despite market
volatility, the Nuveen Money Market Fund continued to provide investors with
attractive short-term rates. As of February 29, 2000, Nuveen Money Market Fund
offered investors a 7-day yield of 4.68%. Please see the Fund Spotlight in this
report for more information.

        In Closing We believe the potential presence of inflation and price
swings in the markets reinforce the importance of working with an advisor,
staying focused on the long term and adhering to your financial plan. With a
sound plan in place, you may be better positioned to weather the markets' ups
and downs. As you pursue your life's dreams, your financial advisor can serve as
a valuable resource in helping you keep market events in perspective while you
focus on your overall financial plan.

        For more information on any Nuveen investment, including a prospectus,
contact your financial advisor. Or call Nuveen at (800) 621-7227 or visit our
Internet site at www.nuveen.com. Please read the prospectus carefully before you
invest or send money.

        Since 1898, Nuveen has been synonymous with investments that stand the
test of time. We are committed to maintaining that reputation and working with
financial advisors to provide investment solutions that help individuals achieve
their lives dreams. Thank you for your continued confidence.


Sincerely,

/s/ Timothy R. Schwertfeger

Notes to Financial Statements


1. General Information and Significant Accounting Policies
The Nuveen Money Market Fund (the "Fund") is a series of the Nuveen Money Market
Trust (the "Trust") which was organized as a Massachusetts business trust on
January 15, 1999. The Trust (and each series within the Trust) is an open-end,
diversified management investment company registered under the Investment
Company Act of 1940.

The Fund invests substantially all of its assets in a diversified portfolio of
high quality money market instruments for current income, the stability of
principal and the maintenance of liquidity.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements in accordance with
accounting principles generally accepted in the United States.

Securities Valuation
The Fund invests in short-term securities maturing within one year from the date
of acquisition. Securities with a maturity of more than one year in all cases
have variable rate and demand features qualifying them as short-term securities
and are valued at amortized cost. On a dollar-weighted basis, the average
maturity of all such securities must be 90 days or less (at February 29, 2000,
the dollar-weighted average life was 13.08 days).

Securities Transactions
Securities transactions are recorded on a trade date basis. Realized gains and
losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. Any securities so purchased are subject to
market fluctuation during this period. The Fund has instructed the custodian to
segregate assets in a separate account with a current value at least equal to
the amount of the when-issued and delayed delivery purchase commitments. At
February 29, 2000, the Fund had no such outstanding purchase commitments.

Interest Income
Interest income is determined on the basis of interest accrued, adjusted for
amortization of premiums and accretion of discounts.

Dividends and Distributions to Shareholders
Net investment income is declared as a dividend to shareholders of record as of
the close of each business day and payment is made or reinvestment is credited
to shareholder accounts after month-end. Net realized capital gains from
investment transactions, if any, are declared and distributed to shareholders
annually. Furthermore, capital gains are distributed only to the extent they
exceed available capital loss carryforwards.

Federal Income Taxes
The Fund intends to distribute all net ordinary taxable income and net realized
capital gains from investment transactions, if any, and to otherwise comply with
the requirements of Subchapter M of the Internal Revenue Code applicable to
regulated investment companies. Therefore, no federal tax provision is required.

Flexible Sales Charge Program
The Fund offers Class A, B, C and R Shares. Class A Shares incur an annual 12b-1
service fee and under limited circumstances may be subject to a contingent
deferred sales charge ("CDSC"). Class B Shares incur annual 12b-1 distribution
and service fees. An investor purchasing Class B Shares agrees to pay a CDSC of
up to 5% depending upon the length of time the shares are held by the investor
(CDSC is reduced to 0% at the end of six years). Class B Shares convert to Class
A Shares eight years after purchase. Class C Shares incur annual 12b-1
distribution and service fees. An investor purchasing Class C Shares agrees to
pay a CDSC of 1% if Class C Shares are redeemed within one year of purchase.
Class R Shares are not subject to any sales charge or 12b-1 distribution or
service fees. Class R Shares are available only under limited circumstances or
by specified classes of shareholders.

Insurance
The Fund has purchased liability insurance to protect against a decline in the
value of securities held in the Fund's portfolio caused by the default of
securities owned by the Fund. The insurance covers substantially all of the
Fund's investments except U.S. Government securities. The maximum total coverage
for all Nuveen money market funds is $50 million, with certain deductibles for
each loss. The Fund pays the policy premiums. Coverage under the policy is
subject to certain conditions and may not be renewable upon expiration. While
the policy is intended to provide some protection against credit risk and to
help the Fund maintain a constant price per share of $1.00, there is no
guarantee that the insurance will do so.

Derivative Financial Instruments
The Fund may invest in certain derivative financial instruments including
futures, forward, swap, and option contracts, and other financial instruments
with similar characteristics. Although the Fund is authorized to invest in such
financial instruments, and may do so in the future, it did not make any such
investments during the period June 10, 1999 (commencement of operations) through
February 29, 2000.

Custodian Fee Credit
The Fund has an agreement with the custodian bank whereby the custodian fees and
expenses are reduced by credits earned on the Fund's cash on deposit with the
bank. Such deposit arrangements are an alternative to overnight investments.

Use of Estimates
The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities at
the date of the financial statements and the reported amounts of increases and
decreases in net assets from operations during the reporting period. Actual
results may differ from those estimates.

3. Securities Transactions
Purchases and sales (including maturities) of investments in short-term
securities during the period June 10, 1999 (commencement of operations) through
February 29, 2000, aggregated $43,975,468 and $35,827,000, respectively.

At February 29, 2000, the cost of investments owned for federal income tax
purposes was the same as the cost for financial reporting purposes.

4. Management Fee and Other Transactions with Affiliates
Under the Fund's investment management agreement with Nuveen Advisory Corp. (the
"Adviser"), a wholly owned subsidiary of The John Nuveen Company, the Fund pays
an annual management fee, payable monthly, which is based upon the average daily
net assets of the Fund as follows:

Average Daily Net Assets                         Management Fee
- ------------------------------------------------------------------
For the first $125 million                             .4500 of 1%
For the next $125 million                              .4375 of 1
For the next $250 million                              .4250 of 1
For the next $500 million                              .4125 of 1
For the next $1 billion                                .4000 of 1
For assets over $2 billion                             .3750 of 1
==================================================================
The management fee is reduced by, or the Adviser assumes certain Fund expenses
in an amount necessary to prevent the Fund's total operating expenses (including
the management fee, but excluding interest, taxes, fees incurred in acquiring
and disposing of portfolio securities, any 12b-1 distribution or service fees
and, to the extent permitted, extraordinary expenses) from exceeding .65 of 1%
of the average daily net assets of the Fund. The Adviser may modify or
discontinue these waivers and reimbursements at any time.

Notes to Financial Statements (continued)

The management fee compensates the Adviser for overall investment advisory and
administrative services, and general office facilities. The Fund pays no
compensation directly to those of its Trustees who are affiliated with the
Adviser or to its officers, all of whom receive remuneration for their services
to the Fund from the Adviser or its affiliates.

5. Composition of Net Assets
At February 29, 2000, the Fund had an unlimited number of $.01 par value stock
authorized. Net assets consisted of $8,406,833 paid-in capital.

Report of Independent Public Accountants




To the Board of Trustees and Shareholders of
Nuveen Money Market Fund

We have audited the accompanying statement of net assets of the Nuveen Money
Market Fund (a series of the Nuveen Money Market Trust) (a Massachusetts
business trust) including the portfolio of investments, as of February 29, 2000,
and the related statement of operations, the statement of changes in net assets
and the financial highlights for the period indicated thereon. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.

We conducted our audit in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the
audit to obtain reasonable assurance about whether the financial highlights are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements.
Our procedures included confirmation of securities owned as of February 29,
2000, by correspondence with the custodian. An audit also includes assessing
the accounting principles used and significant estimates made by management, as
well as evaluating the overall financial statement presentation. We believe
that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the net assets of the Nuveen
Money Market Fund as of February 29, 2000, the results of its operations, the
changes in its net assets and the financial highlights for the period indicated
thereon in conformity with accounting principles generally accepted in the
United States.

DEAR

Shareholder,

Chairman of the Board


Setting financial goals is an important first step toward building wealth. At
Nuveen Investments, we believe those goals should not be considered ends in
themselves. Rather, you and your financial advisor's focus should be on
realizing your life's dreams -- the things that matter most to you and how you
can make them happen -- or make them better.

Through a well-crafted financial plan, you have the chance to shape future
generations -- to broaden your sphere of influence -- to leave your legacy.

As you develop that plan, you'll want to consider the different ways your
success can benefit others. You may find that you want to create a new set of
goals to achieve this. Working with your financial advisor, you have the ability
to make those dreams a reality -- for yourself and future generations.

A Trusted Resource  As you face some of the most important, lasting decisions
you and your family will make, you'll want to draw upon the support, counsel and
objectivity of a trusted advisor. That's because your financial advisor has the
expertise and access to other professionals who can help you make informed
choices -- choices that affect not only your loved ones today, but those your
legacy will touch in the future.

     Your financial advisor can provide sound financial insight, an integrated
approach to your investments and can serve as a knowledgeable friend with your
family's best interest at heart.

     We are dedicated to helping you and your financial advisor develop a family
wealth management strategy unique to you and your goals and values.

Family Wealth Management  Too often, family wealth management is thought of in
one dimension--as the stewardship of your household's financial resources. At
Nuveen Investments, we think of family wealth management as the map to help you
reach your financial, and your life's, destinations. It's a multi-faceted
strategy to plan for not just your needs, but the needs of future generations.

The Economic Environment  You may be reading this report at the suggestion of
your financial advisor. I want to briefly report on the economic environment in
which your Nuveen investment performed.

     The end of your fund's fiscal period, February 29, 2000, was an important
day in our nation's economic life. It marked the 107th month of continued
economic expansion, the longest period of expansion in history. The only period
to rival that length was the 106-month expansion from February 1961 to December
1969, a peri-

     wealth management strategy unique to you and your goals and values."

                                                           ANNUAL REPORT  page 1

Nuveen is dedicated to providing investors access to a team of highly
experienced investment managers, each overseeing portfolios within their
specific areas of expertise. This select group of asset management firms directs
the investment activities of the Nuveen Mutual Funds. Nuveen has chosen them for
their rigorously disciplined investment approaches and their focus on consistent
long-term performance.

Drawing on decades of experience and specialized knowledge, these skilled asset
managers have earned reputations for excellence in their fields of expertise,
whether it is blue-chip growth stocks, large-cap value stocks, bonds or
international securities.

Nuveen's income-oriented funds feature portfolio management by Nuveen Investment
Advisory Services (NIAS). NIAS follows a disciplined, research-driven investment
approach to uncover income securities that combine exceptional relative value
with above-average return potential. Drawing upon 300 combined years of
investment experience, the Nuveen team of portfolio managers and research
analysts offers:

 . A commitment to exhaustive research
 . An active, value-oriented investment style
 . The unmatched presence and trading leverage of a market leader.


od known best for its military conflicts, domestic unrest and soaring inflation.

     That was then; this is now.

     The vigilant inflationary watch of Federal Reserve Chairman Alan Greenspan,
the growth of the Internet and other technology-related developments and the
globalization of the economy are three reasons for continued economic health.

     In their battle to keep inflation at bay, Greenspan's Fed raised interest
rates on February 2, 2000, and again on March 21, 2000. The latest increase
marked the fifth time the Fed has raised the federal funds rate -- the interest
that banks charge each other on overnight loans -- since June 1999.

     Over the short term, the inflation threat has meant increased price
fluctuations in the equity markets. Part of that is due to the fact that
investors and the various markets have been watching -- and reacting to -- every
announcement concerning economic statistics.

     Longer term, we believe there's still faith in the emerging paradigm, which
holds that improvements in productivity enable us to have both economic growth
and low inflation at the same time. The 1960's 106-month expansion that I noted
earlier was fueled by government spending. Today's economy has been fueled by
consumer spending and improved productivity.

Performance Review  I'm pleased to report that despite market volatility, the
Nuveen Institutional Tax-Exempt Money Market Fund continued to provide investors
with attractive short-term rates. As of February 29, 2000, the fund offered
investors a 7-day tax-free yield of 3.31%, which represented a taxable-
equivalent yield of 4.80% for investors in the 31% federal income tax bracket.
Please see the Fund Spotlight in this report for more information.

In Closing  We believe the potential presence of inflation and price swings in
the markets reinforce the importance of working with an advisor, staying focused
on the long term and adhering to your financial plan. With a sound plan in
place, you may be better positioned to weather the markets' ups and downs. As
you pursue your life's dreams, your financial advisor can serve as a valuable
resource in helping you keep market events in perspective while you focus on
your overall financial plan.

     For more information on any Nuveen investment, including a prospectus,
contact your financial advisor. Or call Nuveen at (800) 621-7227 or visit our
Internet site at www.nuveen.com. Please read the prospectus carefully before you
invest or send money.

     Since 1898, Nuveen has been synonymous with investments that stand the test
of time. We are committed to maintaining that reputation and working with
financial advisors to provide investment solutions that help individuals achieve
their lives dreams. Thank you for your continued confidence.

Sincerely,

/s/ Timothy R. Schwertfeger

Past performance is no guarantee of future results.

An investment in the fund is not insured or guaranteed by the Federal Deposit
Insurance Corporation or any other government agency. Although the fund serves
to preserve the value of an investment in the fund at $1.00 per share, it is
possible to lose money by investing in the fund.

Terms To Know

SEC Yield A standardized calculation that the Securities and Exchange Commission
requires mutual funds to use when advertising rates of income return. This
standardized rate ensures that investors are comparing "apples to apples" when
comparing advertisements from different mutual fund companies.

Taxable Equivalent Yield The yield that would have to be earned on a security to
pay as much, after tax, as what is earned from a tax-exempt bond.

Notes to Financial Statements



1. General Information and Significant Accounting Policies

The Nuveen Institutional Tax-Exempt Money Market Fund (the "Fund") formerly, the
Nuveen Tax-Exempt Money Market Fund, Inc., is a series of the Nuveen Money
Market Trust (the "Trust") which was organized as a Massachusetts business trust
on January 15, 1999. Nuveen Tax-Exempt Money Market Fund, Inc. was reorganized
effective after the close of business on June 25, 1999, as previously approved
by shareholders. The Trust (and each series within the Trust) is registered
under the Investment Company Act of 1940 as an open-end, management investment
company.

The Fund invests substantially all of its assets in a diversified portfolio of
high quality, tax-exempt money market instruments for current income, the
stability of principal, and the maintenance of liquidity.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements in accordance with
accounting principles generally accepted in the United States.

Securities Valuation

The Fund invests in short-term municipal securities maturing within one year
from the date of acquisition. Securities with a maturity of more than one year
in all cases have variable rate and demand features qualifying them as short-
term securities and are valued at amortized cost. On a dollar-weighted basis,
the average maturity of all such securities must be 90 days or less (at February
29, 2000, the dollar-weighted average life was 39.6 days).

Securities Transactions

Securities transactions are recorded on a trade date basis. Realized gains and
losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. Any securities so purchased are subject to
market fluctuation during this period. The Fund has instructed the custodian to
segregate assets in a separate account with a current value at least equal to
the amount of the when-issued and delayed delivery purchase commitments. At
February 29, 2000, the Fund had no such outstanding purchase commitments.

Interest Income

Interest income is determined on the basis of interest accrued, adjusted for
amortization of premiums and accretion of discounts.

Dividends and Distributions to Shareholders

Tax-exempt net investment income is declared as a dividend to shareholders of
record as of the close of each business day and payment is made or reinvestment
is credited to shareholder accounts after month-end. The Fund may also
distribute, from time to time, net ordinary taxable income and/or capital gains.

Federal Income Taxes

The Fund intends to distribute all of its tax-exempt net investment income,
taxable ordinary income and/or net realized capital gains from investment
transactions, if any, and to otherwise comply with the requirements of
Subchapter M of the Internal Revenue Code applicable to regulated investment
companies. Therefore, no federal income tax provision is required. Furthermore,
the Fund intends to satisfy conditions which will enable interest from municipal
securities, which is exempt from regular federal income tax, to retain such tax-
exempt status when distributed to shareholders of the Fund. All income dividends
paid during the fiscal year ended February 29, 2000, have been designated Exempt
Interest Dividends. Net ordinary taxable income and net realized capital gain
distributions, if any, are subject to federal taxation.

Insurance Commitments

Effective April 1, 1999, the Fund purchased liability insurance to protect
against a decline in the value of securities held in the Fund's portfolio caused
by the default of securities owned by the Fund. This policy replaces a similar
insurance policy from MBIA Insurance Corp. The insurance covers substantially
all of the Fund's investments except U.S. Government securities. The maximum
total coverage for all Nuveen money market funds is $50 million, with certain
deductibles for each loss. The Fund pays the policy premiums. Coverage under the
policy is subject to certain conditions and may not be renewable upon
expiration. While the policy is intended to provide some protection against
credit risk and to help the Fund maintain a constant price per share of $1.00,
there is no guarantee that the insurance will do so.

Notes to Financial Statements (continued)



Derivative Financial Instruments

The Fund may invest in certain derivative financial instruments including
futures, forward, swap, and option contracts, and other financial instruments
with similar characteristics. Although the Fund is authorized to invest in such
financial instruments, and may do so in the future, it did not make any such
investments during the fiscal year ended February 29, 2000.

Custodian Fee Credit

The Fund has an agreement with the custodian bank whereby the custodian fees and
expenses are reduced by credits earned on the Fund's cash on deposit with the
bank. Such deposit arrangements are an alternative to overnight investments.

Use of Estimates

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities at
the date of the financial statements and the reported amounts of increases and
decreases in net assets from operations during the reporting period. Actual
results may differ from those estimates.

2. Securities Transactions

Purchases and sales (including maturities) of investments in short-term
municipal securities during the fiscal year ended February 29, 2000, aggregated
$1,293,857,568 and $1,404,148,000, respectively. The securities transactions
include the purchases and sales (including maturities) of the Nuveen Tax-Exempt
Money Market Fund, Inc. through June 25, 1999, and the purchases and sales
(including maturities) of the Nuveen Institutional Tax-Exempt Money Market Fund
from such date through February 29, 2000.

At February 29, 2000, the cost of investments owned for federal income tax
purposes was the same as the cost for financial reporting purposes.

At February 29, 2000, the Fund had unused capital loss carryforwards of $44,203
available for federal income tax purposes to be applied against future capital
gains, if any. If not applied, $3,287 of the carryforwards will expire in the
year 2002, $15,535 will expire in the year 2003, $5,800 will expire in the year
2004, $17,809 will expire in the year 2007 and $1,772 will expire in the year
2008.

3. Management Fee and Other Transactions with Affiliates

For the periods prior to the close of business on June 25, 1999, under the
Fund's investment management agreement with Nuveen Advisory Corp. (the
"Adviser"), a wholly owned subsidiary of The John Nuveen Company, the Fund paid
an annual management fee, payable monthly, which was based upon the average
daily net assets of the Fund as follows:

<TABLE>
<CAPTION>
Average Daily Net Assets                                          Management Fee
- --------------------------------------------------------------------------------
<S>                                                               <C>
For the first $500 million                                           .4000 of 1%
For the next $500 million                                            .3750 of 1
For the next $1 billion                                              .3500 of 1
For net assets over $2 billion                                       .3250 of 1
================================================================================
</TABLE>

For the periods prior to the close of business on June 25, 1999, pursuant to the
management agreement, the Adviser was obligated to reduce the management fee or
assume certain Fund expenses in an amount necessary to prevent the Fund's total
expenses (including the management fee, but excluding interest, taxes, fees
incurred in acquiring and disposing of portfolio securities and, to the extent
permitted, extraordinary expenses) from exceeding .45 of 1% of the average daily
net assets of the Fund.

Effective after the close of business on June 25, 1999, as approved by the
shareholders on June 4, 1999, the management fee was as follows:

<TABLE>
<CAPTION>
Average Daily Net Assets                                          Management Fee
- --------------------------------------------------------------------------------
<S>                                                               <C>
For the first $125 million                                           .4000 of 1%
For the next $125 million                                            .3875 of 1
For the next $250 million                                            .3750 of 1
For the next $500 million                                            .3625 of 1
For the next $1 billion                                              .3500 of 1
For net assets over $2 billion                                       .3250 of 1
================================================================================
</TABLE>

Although not obligated to do so pursuant to the new advisory agreement, the
adviser may for limited periods of time voluntarily agree to reimburse certain
expenses of the Fund and had agreed to limit the total operating expenses of the
Fund to .45 of 1% of the average daily net assets through December 31, 1999.

The management fee compensates the Adviser for overall investment advisory and
administrative services, and general office facilities. The Fund pays no
compensation directly to those of its Trustees who are affiliated with the
Adviser or to its officers, all of whom receive remuneration for their services
to the Fund from the Adviser or its affiliates.

Report of Independent Public Accountants



To the Board of Trustees and Shareholders of
Nuveen Institutional Tax-Exempt Money Market Fund

We have audited the accompanying statement of net assets of the Nuveen
Institutional Tax-Exempt Money Market Fund (a Massachusetts business trust)
including the portfolio of investments, as of February 29, 2000, and the related
statement of operations for the year then ended, the statement of changes in net
assets for each of the two years then ended and the financial highlights for the
periods indicated thereon. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial highlights are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of securities owned as of February 29, 2000, by
correspondence with the custodian. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the net assets of the Nuveen
Institutional Tax-Exempt Money Market Fund as of February 29, 2000, the results
of its operations for the year then ended, the changes in its net assets for
each of the two years then ended and the financial highlights for the periods
indicated thereon in conformity with accounting principles generally accepted in
the United States.

DEAR

Shareholder,


Setting financial goals is an important first step toward building wealth. At
Nuveen Investments, we believe those goals should not be considered ends in
themselves. Rather, you and your financial advisor's focus should be on
realizing your life's dreams - the things that matter most to you and how you
can make them happen - or make them better.

Through a well-crafted financial plan, you have the chance to shape future
generations - to broaden your sphere of influence - to leave your legacy.

As you develop that plan, you'll want to consider the different ways your
success can benefit others. You may find that you want to create a new set of
goals to achieve this. Working with your financial advisor, you have the ability
to make those dreams a reality - for yourself and future generations.


A Trusted Resource  As you face some of the most important, lasting decisions
you and your family will make, you'll want to draw upon the support, counsel and
objectivity of a trusted advisor. That's because your financial advisor has the
expertise and access to other professionals who can help you make informed
choices - choices that affect not only your loved ones today, but those your
legacy will touch in the future.

     Your financial advisor can provide sound financial insight, an integrated
approach to your investments and can serve as a knowledgeable friend with your
family's best interest at heart.

Family Wealth Management  Too often, family wealth management is thought of in
one dimension - as the stewardship of your household's financial resources. At
Nuveen Investments, we think of family wealth management as the map to help you
reach your financial, and your life's, destinations. It's a multi-faceted
strategy to plan for not just your needs, but the needs of future generations.

     We are dedicated to helping you and your financial advisor develop a family
wealth management strategy unique to you and your goals and values.


The Economic Environment  You may be reading this report at the suggestion of
your financial advisor. I want to briefly report on the economic environment in
which your Nuveen investment performed.

     The end of your fund's fiscal period, February 29, 2000, was an important
day in our nation's economic life. It marked the 107th month of continued
economic expansion, the longest period of expansion in history. The only period
to rival that length was the 106-month expansion from February 1961 to December
1969, a period known best for its military conflicts, domestic unrest and
soaring inflation.

     That was then; this is now.

     The vigilant inflationary watch of Federal Reserve Chairman Alan Greenspan,
the growth of the Internet and other technology-related developments and the
globalization of the economy are three reasons for continued economic health.

     wealth management strategy unique to you and your goals and values."



                                                           ANNUAL REPORT  page 1

<PAGE>

     In their battle to keep inflation at bay, Greenspan's Fed raised interest
rates on February 2, 2000 and again on March 21, 2000. The latest increase
marked the fifth time the Fed has raised the federal funds rate - the interest
that banks charge each other on overnight loans - since June 1999.

     Over the short term, the inflation threat has meant increased price
fluctuations in the equity markets. Part of that is due to the fact that
investors and the various markets have been watching -- and reacting to -- every
announcement concerning economic statistics.

     Longer term, there's still faith in the emerging paradigm, which holds that
improvements in productivity enable us to have both economic growth and low
inflation at the same time. The 1960's 106-month expansion that I noted earlier
was fueled by government spending. Today's economy has been fueled by consumer
spending and improved productivity.


Performance Review  I'm pleased to report that despite market volatility,
Nuveen's municipal money market funds continued to provide investors with
attractive short-term rates. As of February 29, 2000, Nuveen Municipal Money
Market Fund offered investors a 7-day tax-free yield of 3.01%, which represented
a taxable-equivalent yield of 4.36% for investors in the 31% federal income tax
bracket. The tax-free 7-day yields for the two state money market funds were
2.99% for New York and 2.34% for California. The taxable-equivalent yield for
New York was 4.64% for investors in the 35.5% combined federal and state income
tax bracket. The taxable-equivalent yield for California was 3.74% for investors
in the 37.5% combined federal and state income tax bracket. Please see the Fund
Spotlight in this report for more information.


In Closing  We believe the potential presence of inflation and price swings in
the markets reinforce the importance of working with an advisor, staying focused
on the long term and adhering to your financial plan. With a sound plan in
place, you may be better positioned to weather the markets' ups and downs. As
you pursue your life's dreams, your financial advisor can serve as a valuable
resource in helping you keep short-term market events in perspective while you
focus on your overall financial plan.

     For more information on any Nuveen investment, including a prospectus,
contact your financial advisor. Or call Nuveen at (800) 621-7227 or visit our
Internet site at www.nuveen.com. Please read the prospectus carefully before you
invest or send money.

     Since 1898, Nuveen has been synonymous with investments that stand the test
of time. We are committed to maintaining that reputation and working with
financial advisors to provide investment solutions that help individuals achieve
their lives dreams. Thank you for your continued confidence.

Sincerely,

/s/Tim Schwertfeger

Terms To Know


SEC Yield  A standardized calculation that the Securities and Exchange
Commission requires mutual funds to use when advertising rates of income return.
This standardized rate ensures that investors are comparing "apples to apples"
when comparing advertisements from different mutual fund companies.

Taxable Equivalent Yield  The yield that would have to be earned on a security
to pay as much, after tax, as what is earned from a tax-exempt bond.


Past performance is no guarantee of future results.

An investment in the fund is not insured or guaranteed by the Federal Deposit
Insurance Corporation or any other government agency.

Although the fund serves to preserve the value of an investment in the fund at
$1.00 per share, it is possible to lose money by investing in the fund.

Notes to Financial Statements


1. General Information and Significant Accounting Policies

The money market funds (the "Funds") covered in this report are Nuveen Municipal
Money Market Fund ("Municipal"), formerly, Nuveen Tax-Free Reserves, Inc.,
Nuveen California Tax-Exempt Money Market Fund ("California"), formerly, Nuveen
California Tax-Free Money Market Fund and Nuveen New York Tax-Exempt Money
Market Fund ("New York"), formerly, Nuveen New York Tax-Free Money Market Fund.
Nuveen California Tax-Free Money Market Fund and Nuveen New York Tax-Free Money
Market Fund were reorganized after the close of business on June 25, 1999, as
previously approved by shareholders. As part of the reorganization of the Nuveen
California Tax-Free Money Market Fund, the Service Plan series and the
Institutional series were consolidated and renamed Class A in California. As
part of the reorganization of the Nuveen New York Tax-Free Money Market Fund,
the Service Plan series, the Distribution Plan series and the Institutional
series were consolidated into New York.

Municipal is an open-end, diversified management company incorporated as a
Maryland corporation on July 6, 1982. California and New York are each a series
of the Nuveen Money Market Trust, an open-end management series investment
company organized as a Massachusetts business trust on January 15, 1999.

Each Fund invests substantially all of its assets in a diversified portfolio of
high quality, tax-exempt money market instruments for current income, the
stability of principal, and the maintenance of liquidity.

Each Fund issues its own shares at net asset value, which the Fund will seek to
maintain at $1.00 per share, without a sales charge.

The following is a summary of significant accounting policies followed by the
Funds in the preparation of their financial statements in accordance with
accounting principles generally accepted in the United States.

Securities Valuation

Each Fund invests in short-term municipal securities maturing within one year
from the date of acquisition. Securities with a maturity of more than one year
in all cases have variable rate and demand features qualifying them as short-
term securities and are valued at amortized cost. On a dollar-weighted basis,
the average maturity of all such securities must be 90 days or less (at February
29, 2000, the dollar-weighted average life was 27.37 days for Municipal, 31.52
days for California, and 29.01 days for New York).

Securities Transactions

Securities transactions are recorded on a trade date basis. Realized gains and
losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. Any securities so purchased are subject to
market fluctuation during this period. The Funds have instructed the custodian
to segregate assets in a separate account with a current value at least equal to
the amount of the when-issued and delayed delivery purchase commitments. At
February 29, 2000, New York had an outstanding when-issued purchase commitment
of $1,002,450. There were no such outstanding purchase commitments in either
Municipal or California.

Investment Income

Interest income is determined on the basis of interest accrued, adjusted for
amortization of premiums and accretion of discounts.

Dividends and Distributions to Shareholders

Tax-exempt net investment income is declared as a dividend to shareholders of
record as of the close of each business day and payment is made or reinvestment
is credited to shareholder accounts after month-end. The Fund may also
distribute, from time to time, net ordinary taxable income and/or capital gains.

Income Taxes

Each Fund is a separate taxpayer for federal income tax purposes. Each Fund
intends to distribute all of its tax-exempt net investment income, taxable
ordinary income and/or net realized capital gains from investment transactions,
if any, and to otherwise comply with the requirements of Subchapter M of the
Internal Revenue Code applicable to regulated investment companies. Therefore,
no federal income tax provision is required. Furthermore, each Fund intends to
satisfy conditions which will enable interest from municipal securities, which
is exempt from regular federal income tax and designated state income taxes for
the California and New York Funds, to retain such tax-exempt status when
distributed to the shareholders of the Funds. All income dividends paid during
the fiscal year ended February 29, 2000, have been designated Exempt Interest
Dividends. Net ordinary taxable income and net realized capital gain
distributions, if any, are subject to federal taxation.

Notes to Financial Statements (continued)


12b-1 Plan

Effective after the close of business on June 25, 1999, each Fund pays a fee to
reimburse John Nuveen & Co., Incorporated ("Nuveen"), a wholly owned subsidiary
of the John Nuveen Company, the Funds' principal underwriter and distributor,
for compensating authorized dealers of record, including Nuveen, for providing
ongoing services to the Fund or its shareholders. Nuveen may pay additional
amounts to such firms from its own resources at its discretion, and may retain
any portion of the 12b-1 fees not paid to such firms.

Insurance Commitments

Effective April 1, 1999, the Funds purchased liability insurance to protect
against a decline in the value of securities held in the Funds' portfolio caused
by the default of securities owned by the Funds. This policy replaces a similar
insurance policy from MBIA Insurance Corp. The insurance covers substantially
all of the Funds' investments except U.S. Government securities. The maximum
total coverage for all Nuveen money market funds is $50 million, with certain
deductibles for each loss. The Funds pay the policy premiums. Coverage under the
policy is subject to certain conditions and may not be renewable upon
expiration. While the policy is intended to provide some protection against
credit risk and to help the Funds maintain a constant price per share of $1.00,
there is no guarantee that the insurance will do so.

Derivative Financial Instruments

The Funds may invest in transactions in certain derivative financial
instruments, including futures, forward, swap, and option contracts, and other
financial instruments with similar characteristics. Although the Funds are
authorized to invest in such financial instruments, and may do so in the future,
they did not make any such investments during the fiscal year ended February 29,
2000.

Custodian Fee Credit

Each Fund has an agreement with the custodian bank whereby the custodian fees
and expenses are reduced by credits earned on each Fund's cash on deposit with
the bank. Such deposit arrangements are an alternative to overnight investments.

Use of Estimates

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities at
the date of the financial statements and the reported amounts of increases and
decreases in net assets from operations during the reporting period. Actual
results may differ from those estimates.

2. Securities Transactions

Purchases and sales (including maturities) of investments in short-term
municipal securities during the fiscal year ended February 29, 2000, were as
follows:

<TABLE>

- ----------------------------------------------------------------
</TABLE>

*The securities transactions include the purchases and sales (including
maturities) of the Nuveen California Tax-Free Money Market Fund through the
close of business on June 25, 1999, and the purchases and sales (including
maturities) of the Nuveen California Tax-Exempt Money Market Fund from such date
through February 29, 2000.

**The securities transactions include the purchases and sales (including
maturities) of the Nuveen New York Tax-Free Money Market Fund through the close
of business on June 25, 1999, and the purchases and sales (including maturities)
of the Nuveen New York Tax-Exempt Money Market Fund from such date through
February 29, 2000.

At February 29, 2000, the cost of investments owned for federal income tax
purposes was the same as the cost for financial reporting purposes for each
Fund.

At February 29, 2000, California had unused capital loss carryforwards of
$25,566 available for federal income tax purposes to be applied against future
capital gains if any. If not applied, $18,364 of the carryforwards will expire
in the year 2003 and $7,202 will expire in the year 2008.

3. Composition of Net Assets

At February 29, 2000, the Funds had common stock authorized of $.01 par value
per share. The composition of net assets as well as the number of authorized
shares were as follows:

4. Management Fees and Other Transactions with Affiliates

Prior to the close of business on June 25, 1999, under the Funds' investment
management agreement with Nuveen Advisory Corp. (the "Adviser"), a wholly owned
subsidiary of The John Nuveen Company, each Fund pays an annual management fee,
payable monthly, at the rates set forth below which are based upon the average
daily net assets of each Fund as follows:

For the next $500 million         .475 of 1     .375 of 1
For net assets over $1 billion    .450 of 1     .350 of 1
- ----------------------------------------------------------
</TABLE>

Prior to the close of business on June 25, 1999, pursuant to the management
agreements, the Adviser was obligated to reduce the management fee or assume
certain expenses of each Fund, in an amount necessary to prevent the total
expenses of each Fund (including the management fee and each Fund's share of
service payments under the Distribution and Service Plans, but excluding
interest, taxes, fees incurred in acquiring and disposing of portfolio
securities and, to the extent permitted, extraordinary expenses) in any fiscal
year from exceeding .75 of 1% of the average daily net assets of Municipal, and
 .55 of 1% of the average daily net assets of California and New York.

Effective after the close of business on June 25, 1999, as approved by
shareholders, the management fee was as follows:

- ------------------------------------------------------------
<S>                               <C>            <C>
For the first $125 million        .5000 of 1%    .4000 of 1%
For the next $125 million         .4875 of 1     .3875 of 1
For the next $250 million         .4750 of 1     .3750 of 1
For the next $500 million         .4625 of 1     .3625 of 1
For the next $1 billion           .4500 of 1     .3500 of 1
For net assets over $2 billion    .4250 of 1     .3250 of 1
- ------------------------------------------------------------
</TABLE>

Although not obligated to do so pursuant to the new advisory agreements, the
Adviser may for limited periods of time voluntarily agree to reimburse certain
expenses of the Funds and has agreed to limit the total operating expenses of
the Funds to .75 of 1% of the average daily net assets of Municipal and .55 of
1% of the average daily net assets of California and New York through December
31, 1999.

The management fee compensates the Adviser for overall investment advisory and
administrative services, and general office facilities. The Funds pay no
compensation directly to those of its Directors/Trustees who are affiliated with
the Adviser or to their officers, all of whom receive remuneration for their
services to the Funds from the Adviser or its affiliates.

Report of Independent Public Accountants


To the Board of Directors/Trustees and Shareholders of
Nuveen Municipal Money Market Fund
Nuveen California Tax-Exempt Money Market Fund
Nuveen New York Tax-Exempt Money Market Fund:


We have audited the accompanying statements of net assets of Nuveen Municipal
Money Market Fund (a Maryland Corporation), Nuveen California Tax-Exempt Money
Market Fund and Nuveen New York Tax-Exempt Money Market Fund (each a series of
the Nuveen Money Market Trust) (a Massachusetts business Trust), including the
portfolios of investments, as of February 29, 2000, and the related statements
of operations for the year then ended, the statements of changes in net assets
for each of the two years then ended and the financial highlights for the
periods indicated thereon. These financial statements and financial highlights
are the responsibility of the Funds' management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. Our procedures included confirmation of securities
owned as of February 29, 2000, by correspondence with the custodian and brokers.
As to securities purchased but not received, we requested confirmation from
brokers, and when replies were not received, we carried out alternative auditing
procedures. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the net assets of each of the
respective funds constituting the Nuveen Municipal Money Markey Fund, Nuveen
