Welcome to SIGMAA on Math Circles for Students and Teachers!

A math circle is broadly defined as a semi-formal, sustained enrichment experience that brings mathematics professionals in direct contact with pre-college students and/or their teachers. Circles foster passion and excitement for deep mathematics.

The goal of this SIGMAA is to give math circles greater visibility and a permanent presence in the mathematical and educational landscape. This SIGMAA supports MAA members who share an interest in developing, supporting and running math circles. It works to facilitate vertical integration of elementary, middle and high school students, their teachers, undergraduate and graduate students, and faculty up through high-level research mathematicians.
