January 2004

Dear Friends of the Math Circle,

We should like to thank you for your generous support and wonderful encouragement over the past ten years. Our program continues to grow and flourish.

This year's news includes:

We are continuing our teacher-training program for new teachers, and for those interested in establishing their own Math Circles.

Bob and Ellen are writing Out of the Labyrinth: Mathematics Set Free, which is about the Math Circle; it will be published by Oxford in 2004.

As ever, we rely on the generosity of our friends, which allows us to keep our tuition fees low while covering our operating expenses, as well as maintaining a robust financial aid program.

We are applying for grants for teacher training, strengthening our scholarship program, setting up a capital fund, and expanding to new locales. We ask for your help - either a contribution or, if you're able to, assistance in grant-writing.

Thank you again for considering our needs. As always, we would be delighted to welcome you to any of our classes.

Bob Kaplan & Ellen Kaplan, Co-Founders, and Katie Rae, Treasurer
