I’ve always been a fan of the circumference books. I think they are a great play on words and a great way to learn math skills. They put all of these skills into a story form that makes them more memorable for any age. The new additions have a boring cover, and I wish they would make them more interesting for kids to check out. What really matters is the material inside and it is excellent.

"Sir Cumference and the Dragon of Pi" is an illustrated book that follows Sir Cumference as he is turned into a dragon by a magic potion and his son, Radius, on his journey to turn his father back into a knight. Radius must use his knowledge of circumference and pi to solve the magic math riddle and save the day!
Math content area and medieval culture are shown in this book, as well as many opportunities for themed math activities to engage students and teach them about circles and how to find the circumference or diameter/radius by using pi. It can be used to introduce the concept of pi to students, as well as the connection between pi and circles. The book stresses that pi is a constant and holds the same value in all circles, which is why it can be used to find circumference and area.… (more)

A great introduction on what pi is for kids. Unfortunately, pi is estimated at one seventh, which is a rational number; pi is an irrational number. The names of the characters are creative and pun-ny.
