PUZZLES
Free, fun, and meaningful math for all
Every JRMF puzzle is hands-on, play-based, and standards-aligned. We design our activities to have a low floor so that anyone can find a way to engage and a high ceiling so that everyone can find a meaningful challenge. All of our puzzles come with free festival guides that help you use our activities at home, in the classroom, or during math festivals.
If you’re interested in helping us design new activities, join our blog where we post about a new activity idea each week.
