Sir Cumference and the Dragon of Pi

The Sir Cumference books are amazing. My 9 year old and 5 year old both enjoy them (though the 5 year old is a little young for some of the mathematical concepts just yet). I myself understand pi better since getting this book! I have a grade A at gcse maths but never was taught what pi IS in terms of the relationship between the circumference and the radius.

Fabulous book. Bought it to introduce pi in a fun way to my 11 year old. However my 6 year old loves it too. Who could resist dragons and knights? The story is nicely written with the hero having to complete math problems to save the day.We will be buying other titles in this series for sure.

My kids enjoyed this book, and they will never forget 3 1/7 as a great approximation to pi (I hope). The plot is very similar to the Pixar film BRAVE. Are both stories based on the same story or legend?

This is a great book for introducing mathematics in a fun way. It is a good story for young children and introduces some nice concepts at the same time.

Great book for maths lessons
