Sir Cumference and the Isle of Immeter (Book 5)

Sir Cumference and the Isle of Immeter by Cindy Neuschwander, illustrated by Wayne Geehan

When young Per visits her uncle Sir Cumference and his family, she learns how to play the game, "Inners and Edges." After she finds a clue linking the game to the mysterious castle on the island of Immeter, she must figure out how to find the perimeter and area of a circle to unlock the island's secret. Math skills taught include finding the area and perimeter of a rectangle and a circle. Introduces an underlying concept of calculus — using straight lines to measure curves.

"Sir Cumference returns in this tale that introduces readers to the concepts of perimeter and area. As in previous books, Neuschwander's characters have names that play with mathematical terminology. In this adventure Per visits her uncle and aunt (Sir Cumference and Lady Di of Ameter). After learning a game involving "inners and edges," she and her cousin Radius become embroiled in a mystery with a secret message and a threatening sea serpent. To solve it, the youngsters must travel to the Isle of Immeter and use a series of geometric formulas to tame the sea serpent and bring peace to the "area." Readers already familiar with these formulas will have the most ease understanding and solving the mystery. Teachers introducing the concepts of perimeter and area might find the book useful. Libraries that own the four earlier books in the series will want to consider adding this latest adventure to their collections." - School Library Journal

Why We Love It
