Every summer MathOs runs, we archive it here — sign-ups, what campers told us, and photos from the sessions themselves.

2026 camp

2026 at a glance

July 7 – 30, 2026

2026 was our pilot year, so we ran camp fully online to gauge how the community would react. It was such a hit that we've shifted to a hybrid camp — in person and online — so our out-of-state campers can still join us.
