A funny and pun-filled retelling of "The Sword and Stone" that introduces readers to mathematical angles. King Arthur has hidden his sword, Edgecalibur and issued a challenge to the knights. The first knight to find the sword will be the next king. Can Sir Cumference and Lady Di point Radius's best friend, Vertex in the right direction? Will Vertex's sharp thinking give him the edge? Join Sir Cumference, Lady Di of Ameter, and their son, Radius, in this new adventure where they race to help Vertex find the sword and discover the secrets of cubes, pyramids, cylinders, and cones.
We are enjoying this fun book as a way to illustrate geometry. Similarly, the other books in the series are just as good. Simple presentation of math concepts in a fairy tale format.
Sir Cumference a great way to entertain and teach

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!
