Sir Cumference and the Sword in the Cone

USD $7.99

In Pine and Palm Waldorf teacher and educator Alan Whitehead says, “As an educator, Rudolf Steiner was an ‘integrationist’, an advocate of interweaving and complementing of school subjects. He taught that, through the vehicle of creativity, teachers could bring harmonizing and mutual benefits to subjects as (apparently) disparate math and music, physics and painting, and grammar and games, by a process of synthesis rather than fragmentation. Nowhere is this more vital that in the teaching of math; the study of number in isolation is as currently futile as trying to know the individuality of some long-dead soul by studying their skull.”

This book fits in that description perfectly.

Ages 7-14 (see description below for why)

Although I put this book into the 7th and 8th grade sections of the store I would recommend this book for ages 7 and up. There is no need to explain the mathematical concepts to the child and the stories are really engaging and appropriate for younger children. But imagine their joy and surprise…six years later…when they see these same terms being used in their 7th grade math lessons and instead of being scary terms they are old friends!

Younger kids will enjoy the story and older kids will appreciate the puns and the sense of humor that math can have!

The publisher says: This is 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. Cindy Neuschwander is an elementary school teacher who loves teaching math. She also enjoys traveling, reading, and writing stories. She thought up Sir Cumference while visiting medieval castles in England. Cindy lives in Pleasanton, California.

One fine morning, Sir Cumference, Lady Di of Ameter, and their son, Radius, sat eating breakfast in King Arthur’s castle.

Suddenly, the door flew open and a young knight ran into the room. It was Vertex, Radius’s best friend. “I’ve found out why King Arthur called us all here!” Vertex exclaimed.

“The King wants to choose an heir,” Vertex explained. “Five knights are competing for the honor. I’m one of them.”

 “You would make a fine king,” Sir Cumference said. “That’s right,” agreed Radius. “You helped the King make peace with the Euclideans last year.”

“Yes, but now I have to solve the puzzle on this parchment,” Vertex said. “The King has hidden his sword, Edgecalibur. The knight who finds it will be the next king.”KR
