Book Review: The Greedy Triangle

Posted on Updated on

The Greedy Triangle
Written by Marilyn Burns
Illustrated by Gordon Silveria
Published: 1995, Scholastic Press, 40 pages 
Ages: 5-7
Topic: Educational, Math 

There was a triangle that was very busy as bridge support, sailboat sail, slices of pie, and even as a musical instrument. Triangle loved being in the place right where people put their hand on their hip. The triangle heard all the gossip and told its friends. Well, soon the triangle was tired of being a triangle and wanted new actions. So it went to the shapeshifter. The triangle asked for just one more angle and one more side, which turned the triangle into a quadrilateral. The Greedy Triangle continues as it goes back to the shapeshifter asking for another side and angle. Each new shape is highlighted with activities it does and places where it’s found. Soon it had many sides that were very small and it was difficult to keep its balance. It went back to the shapeshifter asking to be a triangle again.

Marilyn Burns is a former teacher who instructs other teachers to help children understand math concepts. Her principles are well known. I really enjoyed The Greedy Triangle, because it provides shape examples and children can guess what shape will be next with another side and angle. It introduces geometric names (triangle, quadrilateral, pentagon…dodecagon) Math is not boring, but imaginative and fun. The back of the book provides additional information to help teach shapes without being confusing. The book also teaches the importance to be yourself and learn that everyone has something to share.
