Don’t Miss Playful Math Carnivals #155 and #156!


Each monthly carnival brings you a new collection of ideas for playing math from preschool to high school. It’s like a free online magazine of mathematical adventures, helpful and inspiring no matter when you read them.

Explore with your kids or on your own:

John Golden put together an awesome carnival, featuring puzzles, games, slow-reveal graphs, geometry, algebra, math art, puzzles, videos, mobius strips with zippers, and lots more fun. Wow!

Johanna Buijs found a delightful assortment of math tidbits from around the world, inspirational quotations, games, activities, videos, books to check out, and all sorts of mathy fun. Love it!

Help Us Keep the Carnival Going

The Playful Math Blog Carnival wants you!

The carnival is a joint effort. We depend on our volunteer hosts to collect blog posts and write the carnival each month.

Putting together a blog carnival can be a lot of work, but it’s a great opportunity to share the work of bloggers you admire and to discover new math-friends online. I love that part of being a host!

Classroom teachers, homeschoolers, college professors, unschoolers, or anyone who likes to play around with math — if you would like to take a turn hosting the carnival, please speak up!
