*“The Partitions Game” is free on this website for one week only. It’s an excerpt from Let’s Play Math: How Families Can Learn Math Together—and Enjoy It, which is available as an ebook at my publisher’s store (where you get all formats for one low price, and I earn higher no-middleman royalties) or through other online retailers, or by special request through your local library. Read more about my playful math books here.*
