Additional information

We use a nationally recognized math curriculum to help kids become better prepared for more demanding classes in high school and college. We teach the same math topics kids learn in schools, but at a deeper and more challenging level, both reviewing and previewing concepts. The teaching is personalized and welcoming, and takes place in small groups with a high teacher-to-student ratio. CMC is for all students, but we emphasize serving students from groups traditionally underrepresented in STEM: girls, Black and Latinx kids, and kids from low-income families.

We offer classes like Saturday Math Circle and Beast Academy / Art of Problem Solving: Math Classes. This program includes: Problem solving, creative math, puzzles, board games. Visit our website to learn more: Our program is aimed at children who love math, as well as those who don’t love it yet, but would like to.
