More information will be posted soon. Please join our email list to receive a notification when registration opens. You can read information about last summer's program below.

The Summer High School Math Circle is an academically intensive weekday program for students entering grades 9–12 in the fall that runs for three weeks, four hours a day. A typical day consists of a class in the morning, followed by an offline, unsupervised lunch (from 12pm to 1pm), and a problem solving session in the afternoon. Instructors and teaching assistants are very friendly and helpful, and the atmosphere is open and collaborative.

Students are expected to work hard in the program, but also to have fun. Fridays are set aside for unusual activities, mathematical games, team-building, and more.

Our summer program is in its fourteenth year: the first one ran in 2008. The American Mathematical Society has recognized our program with their Epsilon Award for six years now. You can read some of the wonderful comments from past students here.

The Online Summer Program is open to all high school students with an interest in learning and doing mathematics above and beyond the regular curriculum.

Interesting topics and intriguing problems will be explored in a casual setting, providing ample challenges for high school students of varying levels. This program emphasizes problem-solving and posing, through a variety of fascinating topics in number theory, algebra, geometry, and more.

This program is appropriate for students wishing to acquire a deeper insight into mathematics, to develop their reasoning and analytical skills, to practice for a math team, or simply to have fun learning and doing wonderful mathematics.

Students are expected to attend the entire 3-week program.

Attendance Policy

Because we have a limited number of places in our program and out of consideration for students on our waiting list, students should attend the full 3 weeks.


We require all students to be fully comfortable with at least the first year of regular high school curriculum. Priority for the High School Summer Program will be given to students entering grades 9-12 in the fall, and placement into Levels A, B and C will depend on students’ mathematical level rather than grade level. This is an intensive program, and all levels require willingness to work hard.

Online Tools

Google Classroom will be used to manage classroom materials and Zoom will be used for the live sessions. Students are recommended to have a laptop or desktop for these sessions, although a smartphone can be used with limited functionality for the live sessions.
