What's Your Angle, Pythagoras?


by Julie Ellis
illustrated by Phyllis Hornung

A fictionalized story about how a curious boy named Pythagoras first learned about right angles and then, through experimentation and observation, discovered his famous theorem. Full of clever puns and vibrant cartoon illustrations depicting ancient Greece.  This book is a superb way to introduce the Pythagorean theorem in the classroom!

There is quite a bit of text for a picture book but not too much as to take away from the overall success of the book. Indeed, School Library Journal called this book a "clear and interesting explanation of the theorem [and] a wonderful read."
