The Sir Cumfrence series

“The Sir Cumfrence series” is a series of 9 books. Each book turns “difficult” math concepts into very fun stories, such as in one of the stories, they said the word “radius” (half the diameter of a circle) was named after a person called “Radius”. Even though that these books are quite easy for me, I think that this book is still very fun. I’m sure that many other kids out there will really like this series, because it is very childish and it uses very simple words AND a lot of pictures. Each book is about 34 pages long, so I wouldn’t really call it a book. I would rather call it a booklet. There are 306 pages in total. I would recommend you to start reading this at the age of 5.
