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. We are offering FREE trial classes for a limited-time only. Spots fill up fast. Please complete this form to pre-register for a free trial class. Final registration will be confirmed via email, if space is available. 

Currently, we offer two types of classes:

- Math circles: these are enrichment math classes that focus on developing logic, having fun with math, and experiencing it in a way grown-up mathematicians do. There are classes for students in grades 1-2 and 3-5 and are taught by Harvard and MIT students and alums. Price: $75 for a three-week session. Financial aid is available.

- School math with Beast Academy: we are offering classes to deepen your child's understanding of school math topics. Every enrolled student will have full access to Beast Academy online. In class, expert teachers will explain the more challenging concepts, answer questions, and make sure every child is making progress. Price: $150 for a 3-week session. Financial aid is available.

New Resources

We are adding fun puzzles from our archive to our Resource page, for families to use while school is out.

Our Staff

  • Nataliya Yufa received her bachelor’s degrees from MIT in mathematics and physics, followed by a PhD in physics from the University of Chicago. It was in Chicago that she started teaching, working with people of all ages -- school children, undergraduates, and adults. She served three years as a teacher/director of STEM afterschool programs within the Chicago Public Schools, and one year in Houston. These experiences inspired Nataliya to become a full-time math educator, following work as a math education researcher. Since then, Nataliya has taught math at several Boston-area schools, including co-teaching the CSUS math club. She has an M.Ed. from Lesley University in Math Education. 

  • Mira Bernstein received her PhD in math from Harvard University, taught at Wellesley College for ten years, and then left academia to pursue her dual interests in data science and math enrichment education. She runs Canada/USA Mathcamp, an international summer program for mathematically talented high-school students, and helped found Proof School, a school for kids who love math in San Francisco. Her work at a summer math program for underserved middle-school students was featured in the New York Times. Mira’s experience with older students has convinced her of the importance of creating STEM pathways for underserved students, starting in elementary school. She lives in Cambridge and is excited for this opportunity to contribute to her city’s community.

  • Edith Hurwitz is a Harvard undergraduate studying Applied Mathematics. She has been the volunteer coordinator at the the Cambridge Math Circle since 2018. When she graduates, Edith plans to attend law school.

  • Chris Ternoey is a senior instructor with the Cambridge Math Circle. Prior to moving to Cambridge, Chris has lived with his family in Switzerland for many years, running a software company with his wife. Chris has taught with us in many settings and for all age ranges: from kindergarten to adults! 

  • Laura Pierson is a Harvard undergraduate studying Mathematics. Laura has many years of experience teaching mathematics to young people. She has taught at Girl's Angle, as well as the Canada/USA Math Camp. Laura is an exceptionally strong mathematician, as well! 

  • Sophie Woodward is a Harvard undergraduate studying Mathematics. Sophie loves working with kids and they respond in kind!

  • Ben Goldberg is a teacher with over 20 years of experience in working with students of all ages, including many who are neurodivergent. Ben enjoys working with students and is always excited about learning new games.

  • Sasha Brownsberger is a Harvard graduate student working in Physics. Sasha has many years of teaching experience under his belt. He loves working with kids and solving new problems, when not working on his astrophysics research.

  • Noah Olsman is a postdoc at the Harvard Medical School. Noah has taught enrichment mathematics in California, prior to moving to Cambridge. Noah delights in pushing student thinking by exposing them to new problems.
