This book is based on the legend of King Arthur and the round table which is said in medieval times. During the story, we are introduced to Sir Circumference, Lady Di of Ameter, and their son Radius. Sir Circumference is trying to create a table that would bring unity and promote discussion without having to yell across the room to be heard. When Lady Di heard of this problem she said that Sir Circumference should make a round table. This book introduces readers to basic geometry and encourages the growth of critical thinking and problem-solving skills. ( )

Intermediate
SIr Cumference needs to build a table for all the knights. He tries, squares, triangles, all kinds of shapes, but nothing works! Finally, he discovers that a circle is the best shape.
I'd only use this book if I was doing a specific math lesson about geometry or circumference. If I was doing it with kids older than 6th grade, I wouldn't use it because it is a bit juvenile. The art is good and draws you in, and the characters are funny

This book has a great way of using imagination and creativity to make math fun and interesting and is good to use for middle school students in 6-8 grade. Students in this age groups are learning how to measure the circumference and area of a circle, not only that but it helps with other concepts of shapes as well. ( )

Part of a series of fun, Medieval adventure stories that introduce mathematical concepts for young readers. This one introduces a bit of plane geometry, including the concepts of radii, circumferences, and diameters. ( )

This book tells the story of King Arthur and his knights, but the names of all the characters are mathematical names in this book. This is a fun way for students to see how to use these terms in a way that will stay with them and they can be engaged with. I would use this book to introduce the topic of finding circumference using diameter and radius. ( )
