Radius, son of Sir Cumference and Lady Di of Ameter, takes on a Math Adventure by Degrees!
More than anything, Radius wants to be a knight. To earn his knighthood, he needs to venture alone on a heroic quest.
With only a circular family medallion (protractor), a mysterious poem, and his own wits to guide him, he must find and rescue a missing king. But he must also watch out for dangers and dragons!
The ultimate challenge lies in a mysterious castle with a maze of many angles. Which way would you go if you were Radius? With the medallion included at the back of the book, you can join in on the adventure!
Though your math student will read this book for fun, there's much to learn here about angles, such as the different types of angles (acute, right, obtuse, and straight angles) and how to measure them with a protractor.
Use this book as an enjoyable introduction to angles, or as a fun reward for good math work!
