This book is written in an interesting narrative, and couples the story with the math concept of ratio and proportion. Pythagoras gets distracted from his chores, as he works on how to construct musical instruments that will harmonize. The ending is very humorous! I had been searching for a book that addressed the topic of ratio, and this book serves the need well. A must add to a teacher's literacy library!

This story introduces your children to the ancient Greek philosopher-mathematician Pythagoras in a way that isn't such a yawner as they get in the blurb in their math textbook.

But...

The story has more to do with the ratios of musical tones in a chord, than with ratios in real life.

In addition to this book, which will help your child remember the still-brilliant Pythagoras, try "Beanstalk: The Measure of a Giant" by Ann McCallum.

This is a cute, fun read. However, I did not like this book as much as What's Your Angle Pythagoras? That book did an excellent explaining how/why the Pythagorian Theorem works. I was expecting the same from this book. It semi explains what ratios are,but I felt the story lacked the mathematical explanation that was so prominent in the first book.

A very nice treatment of ratios that math students can easily relate to. Kid-friendly illustrations round out this book. Pair it with the Sir Cumference books.

Good way to add literary content to math...thinking of creating a reader's theater from it!
The last page/inside back cover containing information about Pythagoras is a great starting point for a special project on the Old Greek (Math) Guys, too.
