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 our outreach activities, sign up for our newsletter at the bottom of the 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. One festival early in the year is geared toward girls, and our spring festival is open to everyone.

Sign-ups for our festivals will come soon. Save the date!

Spring Math Festival


We host the San Francisco Math Teachers’ Circle.

Proof School is 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. These engaging and activity-based gatherings are held on Saturdays from 9:30am-12:00pm.
