Sir Cumference Math Books

Save During Our Sir Cumference Math Books Sale!

Cleverly written and delightfully illustrated, the Sir Cumference math adventure books are very helpful for learning about the basics of geometry. Cindy Neuschwander has written five books in the series to help children learn about pi, angles, shapes, and more.

When I first learned about them, I had my doubts. How can you use geometry to make an interesting children's book? Once I started reading them, I had to finish all five! Each book kept me guessing until the end. These can definitely count for reading AND geometry.
