Sir Cumference and the Dragon of Pi (A Math Adventure)
Posted on March 7th, 2010 in CHARLESBRIDGE PUBLISHING | No Comments »
This is a great book. It has lots of mathematical elements while also being fun for middle school students. I, as a math teacher, enjoyed reading this book to my students. The math terms that tie the book together are very creative in the way they are presented. If you are reading this book to a class of middle school students, it will take from ten to fifteen minutes to read completely if the class is attentive. The math described in the book can help students to remember those terms later.

Great Product!!!
The book was in better condition than I expected of a used book. It looked like new!!

Great Book!
I used this book on Pi Day in my middle school math classroom. My students loved it! I think that it really helped explain why Pi is a constant number and it works for every circle!

Fun, Funny, and For a Big Age Range
As a fifth/sixth grade teacher, I find all of these "Sir Cumference" books to be interesting to students at every stage of learning about the math concepts they present. This is the one mathematically-flawed book in the series, however, which accounts for the 3 star rating. The young boy, Radius, searches for a cure for his father's unexpected transformation into a dragon, and 3 and 1/7 works as the value for pi needed to restore him to human form. It's a bit nit-picky of me, perhaps, but one of the most essential things a student should learn about pi is that it is a non-terminating decimal value which got a name because it couldn't be accurately quantified. That said, any teacher (or interested parent) could clear up the fuzzy definition. The books are funny, brief, written on a relatively easy level, and -- while most likely to be appreciated fully by students who have already learned the math -- could be enjoyed as stories by even the youngest listeners, as other parent/teacher reviewers have affirmed. This book, like the others, does a good job of using verbal jokes to help secure math vocabulary.

We love this series!
A great resource for homeschoolers or parents of high ability kids who need a different approach -
My children (8 and 4 yr.) love every story in this series.
Bravo to Cindy Newschwander - Creative, engaging, problem solving, and Dragons! What more does a young math student need?
We own the entire Sir Cumference series and revisit them regularly as the concepts take root in our daily lives.
Great books, every one.
