*Playing With Math: Stories from Math Circles, Homeschoolers, and Passionate Teachers*is over. We reached our original goal of $7500 on Sunday, July 6, after only 17 days, giving us the funds we need to publish this fabulous book. Our stretch goal is $4000 more, for the Spanish translation. We are about halfway there, but we only have 3 days left. Can we make it?

If you haven't reserved your copy yet, please do it now!

While I was visiting family and friends in Michigan, I spent some time this past weekend with my friend Chris (who has helped with the book from the very beginning). While our kids played in the pool, we discussed index entries, and which terms might need cross-referencing. For example, Jamylle Carter had students build their own

*inclinometers*, and wrote about it in her chapter on the Oakland Math Circle. If you had read about them, forgotten the word, and wanted to re-read her description a year later, you might think of them as angle-measuring devices, and look up angle. So we’ll cross-reference her inclinometer description under

*angles, measurement*.

Here's a picture of an inclinometer. (The boy was drawn with a photo of my son as the model. He's older now.)
