Welcome to Washington, D.C.!

Welcome to the largest, most exciting annual gathering of mathematics educators in the world. The 87th Annual Meeting and Exposition of the National Council of Teachers of Mathematics brings together outstanding classroom teachers, mathematics educators, and mathematicians to share what they know and to exchange ideas in support of helping every student learn challenging mathematics. On behalf of the Board of Directors, Program and Local Arrangements committees, staff, and the many volunteers who have worked long hours to put together a spectacular set of opportunities for you, welcome to Washington, D.C.

Equity, the theme of the conference, provides just a glimpse of what the conference will offer. Our Program Committee has put together an exceptional group of presentations for you to explore and consider the complexities of teaching mathematics so that all students will learn. You will find presentations that challenge you to examine your own teaching, your connections

to your students and their community, and your perspectives on mathematics.

There is much more to the conference than the more than 825 presentations planned for your professional enrichment. Over the next three days, take advantage of the extraordinary opportunities you'll have to meet new colleagues and to form stimulating professional and personal relationships that can last a lifetime. To really experience Washington, make sure you visit the Mall, the Smithsonian, Capitol Hill, and the nearby Spy Museum and downtown area. Enjoy the local culture and cuisine, and get out and see the beautiful springtime blossoms. You may be surprised at how mathematical Washington is, in addition to being a vibrant hub for history, art, dining, and shopping.

Our hope is that after your Washington, D.C. experiences you will return to your classroom and colleagues brimming with new ideas and questions that will expand your thinking about the mathematics you teach and the students whose lives you influence every day.

On behalf of the NCTM Headquarters staff, it is my great pleasure to welcome you to the Council's 2009 Annual Meeting and Exposition. We assemble in the capitol city of the United States to learn, to network, and to advocate. In this dynamic and ever-changing setting, we can gain new insights on helping all children achieve success in mathematics. We can discover new ideas and approaches from session and workshop leaders. We can examine the latest educational materials, and network with teachers from across North America and the rest of the world. At a time when science, technology, engineering, and mathematics (STEM) education is on the minds of this nation's policymakers and legislators, it is appropriate to gather together in Washington, D.C. All around us we can see and hear

the challenges of a busy urban setting, the discussion of global competitiveness and its environment, and the desire to meet the needs of the world's peoples. This venue is, indeed, symbolic of the challenges we collectively and individually face in making a brighter future for all children. Again, welcome, grow, and enjoy NCTM's Annual Meeting and Exposition.
