Math Teachers’ Circles are professional communities of K-12 mathematics teachers and mathematicians. Groups meet regularly to work on rich mathematics problems, allowing teachers to enrich their knowledge and experience of math, while building meaningful partnerships with other teachers and mathematicians.

“Math Teachers’ Circle activities reinforce my feeling of math as a creative endeavor. I try to pass this attitude on to my students.”

The Math Teachers’ Circle Network organizes Math Teachers’ Circles around the country and provides support and resources to new and established Circles. There are currently 115 Math Teachers’ Circles and six regional MTC networks across the U.S. Find a Circle in your area, or learn how to start a new Circle.

“I am more confident than ever that there is a way to reach students.”

The Math Teachers’ Circle Network is a project of the American Institute of Mathematics, one of eight U.S. mathematical sciences research institutes supported by the National Science Foundation. The Math Teachers’ Circle Network is also generously supported by the American Mathematical Society, the Educational Advancement Foundation, the Mathematical Association of America, Math for America, and the National Security Agency.

What’s a Math Teachers’ Circle Meeting Like?

We recommend you check out our videos. We are also happy to help coordinate an in-person or virtual visit to a Math Teachers’ Circle if you contact us.


A Culture of Problem Solving

The article “Be Less Helpful” by Joshua Zucker gets at the mathematical heart of Math Teachers’ Circles.


Meet Our Circles

We invite you to learn more about the MTC of Hawai’i, one of our most successful and innovative groups. And then visit the Philadelphia Area MTC, which beautifully articulates its role in teachers’ lives.


The Bigger Picture

Our vision is to contribute to a broader and more inclusive mathematical community, with the goal of transforming mathematics education in the U.S.


MTC Network Named as Partner in 100Kin10

America needs more excellent STEM teachers, and we have committed to action as a new 100Kin10 partner! Learn more about our role in this national movement.
