Read an Excerpt

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.”

Editorial Reviews

Gr 3-5-Neuschwander retells "The Sword in the Stone" from a mathematical angle. Readers follow along with Sir Cumference and Lady Di of Ameter as their son Radius and his friend Vertex set out to find Edgecalibur. Filled with riddles and puns, the story is sure to delight students with some geometry background. Geehan's bright oil, acrylic, and pen-and-ink paintings include all the visual details that the text needs to help solve this geometrical mystery. If your students have enjoyed the first three books in the series, they will certainly want this one. Make sure to share these gems with your math teachers. The books can be used to support educational initiatives such as multiple intelligences, and students who are strong in verbal/linguistic areas will appreciate the integration of literature into their math lessons.-Christine E.
