Mummy Math: An Adventure in Geometry by Cindy Neuschwander. Reviewed by DJ, age 9.
Ages 5 - 10 and older for picture book lovers. Cindy Neuschwander writes the Sir Circumference books so I checked this one out. Turns out I don't like to read it aloud (it reads very much like a script to a Cyberchase episode), but that's no problem, my 9 y/old happily read it to his sisters. They love Cyberchase, so the language fit his taste wonderfully. Amazon has it for 9 to 12, but that's inaccurate imo.
It's about geometric solids, and follows the adventures of a couple kids and their dog through an Egyptian pyramid following clues based on these shapes. Cindy includes notes on the back page to help you extend learning about the ideas through other activities.
There is a lot of math in the chapters that the Mathemagician and the Dodecahedron appear in. If you have my book, page 188 has QUITE an interesting equation, I dare you to do it (no cheating by looking at page 189!)
I recommend this book for readaloud 6 and up, readalone 9 and up. I rate it an 8 out of 10.
