Iva Sallay, who kindly runs the FindTheFactors mathematics puzzle, is the host of the Playful Math Education Blog Carnival this month. She’s just published the current, 146th, edition.

These carnivals often feature recreational mathematics. Sallay’s collection this month has even more than usual, and (to my tastes) more delightful ones than usual. Even if you aren’t an educator or parent it’s worth reading, as there’s surely something you haven’t thought about before.

And if you have a blog, and would like to host the carnival some month? Denise Gaskins, who organizes the project, is taking volunteers. The 147th carnival needs a host yet, and there’s all of fall and winter available too. Hosting is an exciting and challenging thing to do, and I do recommend anyone with pop-mathematics inclinations trying it at least once.
