The San Joaquin Math Teachers’ Circle is part of a growing national network of Math Teachers’ Circles established by the American Institute of Mathematics (AIM) in San Jose, CA. In June 2012, our team attended a “How to Run a Math Teachers’ Circle” workshop. Since then, we have been providing monthly opportunities for middle school math teachers to broaden their expertise with problem solving. The San Joaquin Math Teachers’ Circle enlists the support of local mathematicians from the University of the Pacific, as well as experienced MTC facilitators from the American Institute of Mathematics.
