Buy Sir Cumference and the Dragon of Pi: A Math Adventure Illustrated by Neuschwander, Cindy, Geehan, Wayne (ISBN: 9781570911644) from desertcart's Book Store. Everyday low prices and free delivery on eligible orders. Review: Clever tale with interwoven maths. - 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. Review: Brave approach to pi - 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?

Clever tale with interwoven maths.
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.

Best math story book so far.
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.

子供が腹痛の父親のために持ってきた薬が、な・な・なんとドラゴンにかわる薬だった。父親を元に戻すための薬の量がわからない。それを解き明かすうち、円周率を発見するというお話。なかなか、おもしろいお話でした。話の内容が、おもしろいので５歳の子供でも楽しめました。
