Books to Teach Circumference and Pi
You cannot go wrong with geometry series Sir Cumference by Cindy Neuschwander. Math Geek Mama has a post explaining how to get most of Sir Cumference books and she also has a great free printable activity for Sir Cimference and a Dragon of Pi.

A little off topic, but what kind of a compass do your kids have? Smarty hates cheap compass thingies with a pencil, because they slip and it's difficult to draw a perfect circle with them. Since my husband does not want to share his precious compass with her, I want to give her a good quality compass as the beginning of a school year gift.
