We aim to share our love of math with the broader community.

We think math is irresistibly fascinating and hope that you will agree.

Proof School aims to cultivate a love of mathematics not just in our students, but also in the broader community. Annual student-run math festivals have been a cornerstone of our community outreach since our very first year as a school. Please join us at one of our math festivals if you’re a student, or at a meeting of the San Francisco Math Teachers Circle if you’re a teacher.

To receive up-to-date information about outreach activities open to the community, sign up for our newsletter at the bottom of this page. 



Our math festivals capture the imaginations of curious kids.

Each year, Proof School students and faculty host two math festivals aimed at kids who love math—and kids who want to love math. 

Join us to spend the morning playing math games, tackling math puzzles, trying out mathematical art projects, and more! These festivals are geared toward students in 4th-8th grades.

We host the San Francisco Math Teachers Circle.

Proof School is again hosting the San Francisco Math Teachers Circle. 

If you're a math teacher and want to learn interesting mathematics that leaves the textbook far behind, join the Math Teachers Circle.

The Math Teachers Circle takes place at Proof School and is coordinated by Cornelia Van Cott, Chair of the math department at USF. These engaging and activity-based gatherings are held on Saturdays from 9:30am-12:00pm. Coffee and food are provided.

Please contact Cornelia Van Cott at [cvancott@usfca.edu] for more information and to get on the mailing list.
