Learning, up close

We take ideas seriously, with classes built around discussion, collaboration, and problem-solving. Students are known well enough for teachers to support and stretch them. At Proof, curiosity shapes the day, and students struggle meaningfully — together rather than on their own.

Small by design

We started small, and we saw how much that matters. Students learn with peers younger and older, friendships form across grade levels, and students step into leadership naturally. When we think about growing our school, we first ask what makes our kind of community possible.

Thinking, seeing & growing
through mathematics…

…with plenty of time to ā€œstruggle with itā€ ā„¢

Real understanding takes patience, and the willingness to stick with it. Students grapple with unfamiliar problems, derive results, and write formal proofs. Extended class time makes room for inquiry and focus — aĀ­cross the school, we care far more about thinking well than moving quickly.

Love math?

There are many ways to love math. The students who thrive with us enjoy puzzles and patterns, explain their thinking, and care deeply about why things work. A student who excels at computation may still find our math challenging in a different way. At Proof, we value reasoning, clarity, and persistence.

We take ideas seriously, not ourselves.

Outside the classroom

Our space is new, but our culture isn’t. Since our first year, students have rushed to the ping pong table at break, taken sides in good-natured flame wars, and gathered across grade levels to play The Resistance. Out of the classroom, it feels like recess. We keep the work hard and the atmosphere light.ā€ ā€

Outreach

Part of our mission is to positively impact the world around us. We run math festivals and a summer camp, and we host the San Francisco math teacher’s circle, giving Bay Area educators a bevy of professional development opportunities.

Not a school where everything happens,
but a school where anything is possible.
