Sir Cumference and the Dragon of Pi: A Math Adventure

Rating:
Summary: Good Intro to Pi
Review: Sir Cumference and the Dragon of Pi is the story of a boy that must use math to save his father. Most of the character's names are terms found in math, like Sir Cumference and Radius, which cleverly adds to the effect of the story. The use of a dragon gives the story more of a fantasy feel which appeals to the younger audience. The illustrations in the book are done well and add to the medieval setting of the book because they look like oil paintings. The goal of this book is to introduce kids to the concept of pi in a fun and easy to understand way. It pulls this off by having a fairy tale setting and actually having a reason to use pi that kids can understand. This book is not a quick read, yet it's not long enough to lose the attention of a child. Even though this is a children's book, it should only be used for older children since it involves division with fractions. Because of this, it works as a great educational tool for those older children by introducing them to a fundamental math term they will most likely use later in life.

Summary: Excellent Conceptual Intro
Review: The Dragon of Pi is an excellent conceptual introduction to Pi, a concept not even clear to most adults, for children. The ideas are clear and playfully woven into the plot. Using the globally favorite dragon as a character, this book is animated, informative, and an effective educational tool.

Summary: Very disappointing
Review: The story is REALLY silly.
Moreover, throughout the book the value given to Pi
is WRONG (it is stated to be 22/7, and only at the very end is it casually mentioned to be an approximation).
This book is a perfect example of how NOT to attract kids to Math.
