Classes (Winter 2024)

You can see our planned schedule for Winter 2024 on this page. To stay updated every term, sign up for our mailing list to find out when registration opens. 


We run two kinds of classes. Math Circle classes encourage the love of mathematics, develop problem solving skills, and explore math that isn’t covered in the mainstream public school curriculum. Beast Academy/Art of Problem Solving classes (including PreAlgebra, Algebra 1 and Algebra 2) are in-depth and fun ways to do curriculum-related math. Check out our FAQ for more. Registration is on a first-come, first-served basis, and classes often fill up.

Your student might need an evaluation before they can participate. See our evaluations policy below.

For Fall 2023, Beast Academy/Art of Problem Solving classes will be held after school on Zoom. Math Circle classes will be in-person on Saturdays, with a choice between morning or afternoon time slots for each age group.

Evaluations policy


You can expect an email from us about scheduling an evaluation before enrollment if you're in either of the following situations:

1. If this is your student's first time in Beast Academy or Art of Problem Solving, or they're coming back after a long gap, we need to evaluate them. In rare cases, students are far enough behind that we determine they would do better in another program, but in general this evaluation determines placement, not admissions. If your student requires evaluation for Beast Academy/Art of Problem Solving, the deadline for applications is December 31st.

2. If your student is in 1st grade and applying to Saturday Math Circle classes, we will need to evaluate them first. Only students with strong reading and math skills can join in first grade, because both the problems and the social environment can be very challenging. We reserve the right not to admit a first grader for any reason. If your student requires evaluation for Math Circle, the deadline for applications is January 10

To be evaluated, all you need to do is fill out an application by the deadline and wait for us to get in contact with you to schedule it. Apart from 1st graders, no evaluation is needed to participate in Saturday Math Circle—we will place your child in a small group with similar children.

If you miss these deadlines, you can still apply, and you will be put on the waitlist. We will try to admit you in the following weeks, but cannot guarantee admission.



The email you receive after applying is not a confirmation of admissions; it's an acknowledgment that we've received your application. If your child is admitted, you will receive at least two more emails from us: one welcoming you and letting you know your child's time slot and financial aid award, and one with your invoice.

Registration for Summer Camp 2023 is open! Click the link below to register. For school-year classes, see here.

Cambridge Math Circle Summer Camp


Who is this for: kids who like puzzles, board games, and want to learn fun math.

Age range: kids entering grade 3-8.

I have a very bright child who isn't a rising 3rd grader yet. What do I do?

We are very glad that you've found us, and we thank you for your interest! However, many of our students are very passionate mathematicians, and therefore our problems tend to be quite challenging and many years ahead of what the kids are learning at school, so our camp is not a good fit, even for the brightest kids younger than rising 3rd grade. We look forward to seeing your kids in our regular classes when they reach the required age. In the meantime, you might want to look into Beast Academy Level 1 online or in book format!


Regular times below. Extended day available upon request (early drop off (starting at 8:30 and late pick up at 5 pm))

  • 1 Day - June 23, 9 am - 2:00 pm (waitlist for all grades)

  • Week 1: June 26 - June 30, 9 am - 2:00 pm (waitlist for grades 3-5, available for grades 6-8)

  • No Camp for 4 weeks in July

  • Week 2: July 31 - August 4, 9 am - 2:00 pm

  • Week 3: August 7 - August 11, 9 am - 2:00 pm

Location: Harvard University (near Harvard Square)

Cost: $120/day, $600 for full week. Scholarships are available for low-income families, with a focus on Cambridge residents.

$150/week for extended day until 5:30 pm (not available for Week 2).

Join us for an in-person summer camp, where kids will solve logic puzzles, learn problem solving techniques, play board games, and learn about the lives of mathematicians. Every 45 minutes or so there will be a movement break. Space is extremely limited. Need-based financial aid is available, with a focus on Cambridge residents. Registration closes 1 week before the start of the session in question. First come, first-served.


Space is very limited, and we keep groups very small, so please only fill in the application form if you are sure your child will be able to come to camp. 

Note: a $30 application fee is added per child per summer. Need based waivers available ($0 fee for low-income families).
