Our Story


The Cambridge Math Circle was established in 2018 by math and physics PhD's with a combined 40 years of teaching experience at K-12, undergraduate and graduate levels, to give elementary and middle school students in Cambridge and surrounding towns a chance to experience deep, fascinating math and meet others who like solving puzzles and stretching their minds.​​

CMC aims to serve all students, with a special focus on those who are traditionally underrepresented in STEM fields.

What We Do


As of March 2020, our instruction is exclusively online. In Spring 2020, we offered a variety of math circles online -- ones accessible to any student in grades 1-8, which had a cost, as well as free circles for residents of Cambridge, MA, both citywide and for students at certain schools. We served approximately 140-150 students each week in about 15 sessions each week. 

In the summer of 2020, we offered a number of camp sessions to fit the needs of families: we have camps lasting 1, 2 and 3 weeks. There are also two types of camps: one that is more extensive, and has 3 meetings of 3 hours each week, and another that meets twice a week for 45 minutes, with an online system students can use between classes to "play math."
