Join us for the 2021 National Math Festival, with hands-on, interactive activities for youth of all ages, plenty of booths to stroll around and pick up resources for math play at home or in the classroom, and engaging films and lively math talks to round out the program.

• Expect dozens of simultaneous live, hands-on mathy play sessions for all ages, resource booths staffed for live, on-camera chats with math fun experts from leading math organizations, and a chance to meet math lovers from around the U.S. and around the world and fall in love with math in new and surprising ways together.

• As ever, the NMF is free and open to the public, with activities designed for all ages, from very young children to adults. We invite you to celebrate the fun, beauty, and power of math through games, puzzles, math, magic, uplifting and intriguing talks, beautiful and engaging films and film panels, live performances, and much more.

The National Math Festival is organized by the Mathematical Sciences Research Institute (MSRI) in cooperation with the Institute for Advanced Study (IAS) and the National Museum of Mathematics (MoMath). The 2021 NMF is generously supported by the Simons Foundation, the Alfred P. Sloan Foundation, the National Science Foundation, Schmidt Futures, the Kavli Foundation, and the American Mathematical Society (AMS).
