Some years ago, we stumbled upon these books at the library. They were an instant hit - every single one in the Sir Cumference series! We check out lots of books but this one the children remembered. In fact, we hadn't checked these out for a couple of years when one son started a new geometry section in math and asked me to get these again so he could review! My preschooler thinks of these as fun stories and enjoys the illustrations while the older crew is making the connections to mathematical concepts they are learning. For example, one child always keeps diameter and radius straight because of the book characters (Radius is the little guy!). I highly recommend this series as enjoyable literature that will help your children remember their geometry. The books also have an object or character (jester, seagull, rat, cat, etc.) that appears on most pages which is an extra bit of fun to look for. I love the rich colors and oil painting technique too (I may be wrong about the oil painting but that's the feel of it). I decided these belong in our home library and was especially pleased that was running its buy 3 get 1 free promotion just then.

I purchased the whole set for homeschooling purposes and it really drives home the concepts in a fun way with the kids not realizing they are learning geometry. This is as fun as Cyberchase in a book format. Highly recommend these!

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.

The Sir Cumference books are great for kids interested in math. My 8yo son, who loves math, devours these, though my 8yo daughter who is not interested in math, finds these uninteresting as well. But they teach concepts in a really great, fun way.

As I read this story aloud to my 7th graders, students cut nets to fold and make solid figures. They count the faces, vertices, and edges along with the story-line and even prove the "rule of two" by Euler.

My five year old loves this series and he does not realize he is learning math skills. His vocabulary now includes some interesting math terms ( although he does not realize it). We now have almost all of the books.

I recently read these to my younger brothers and they loved them! They definitely learned a lot too! This book explained faces , edges, and vertices. It also explained the "rule of two" or "Euler's law". Overall this book is great, along with the entire series!

Maybe starting off reading the 6th math adventure in the Sir Cumference series wasn't the best place begin. I appreciated the use of math terms such as: face, points, edges, cylinder and more; but found the math solving pace to be faster than most readers would be able to follow. This would be fun book to create a lesson around for any geometry class though.
