Join us for the 2021 NMF Live Online Weekend starting Friday, April 16 through Sunday, April 18, 2021!

Enjoy hands-on, interactive activities, 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.

The NMF is a youth-centered environment, with moderated chat, live support staff at the online help desk during Festival hours, and dedicated activities for every age group: 2-4, 5-7, 8-10, 11-13, 14-18, 18+, and All Ages.

This is family math inspiration at its best. Drop in and out throughout the weekend. Stay a few minutes, or a few hours. Take it easy, or dive deeply: Both approaches will be fun during this exciting community-building weekend. As ever, the NMF is free and open to the public.

You can also check out the event schedule in advance, or simply join us April 16-18 and see what's live!
