Don’t Miss Playful Math Carnivals #158 and #159!


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:

Alexa Kapor-Mater put together an awesome carnival, with fun facts, activity ideas, puzzles, videos, problem-solving tips, and interesting stuff you should know. Wow!

John Golden found a delightful assortment of playful tidbits from around the internet, fun songs, games, activities, puzzles, math art, and the #Mathober challenge prompts. Love it!

Help Us Keep the Carnival Going

The Playful Math Blog 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. 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.

Check the details on the carnival’s home page, and then leave a comment here on the blog or email me directly to let me know when you want to host.
