Welcome to the American Institute of Mathematics Math Teachers' Circle. Founded in 2006, the AIM Math Teachers' Circle is the original member of the national Math Teachers' Circle Network.

Every month from September to April (except December), the AIM Math Teachers' Circle will offer an evening meeting for middle school math teachers interested in exploring accessible, exciting topics in mathematics and learning about a problem-solving approach to teaching math. All teachers are welcome to attend. Meetings include dinner, which is complimentary.
