Book Description

Feb 2010
Julie Ellis and Phyllis Hornung Peacock team up once again to explore Pythagorean ratios in this humorous sequel to WHAT'S YOUR ANGLE, PYTHAGORAS?

Pythagoras and his cousins want to win a music contest, but first they must figure out how to play their instruments in tune, something that's never been done before.
While trying to fix the problem, Pythagoras makes an important discovery--notes that sound pleasant together have a certain mathematical relationship. When Pythagoras applies this ratio to his cousins' pipes and lyres, the result is music to the ears.

5.0 out of 5 stars a needed topic 2 April 2010
By C. M. Woodworth - Published on Amazon.com
Format:Paperback|Verified Purchase
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!

4.0 out of 5 stars Good on Pythagoras 14 Oct 2011
By M. Heiss - Published on Amazon.com
Format:Paperback
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.

3.0 out of 5 stars Not quite what I expected 10 May 2014
By Priscilla Caporaletti - Published on Amazon.com
Format:Paperback|Verified Purchase
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.

5.0 out of 5 stars Math made simple 24 Feb 2013
By Kath's kudos - Published on Amazon.com

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.
4.0 out of 5 stars Literacy in Math 18 Jun 2014
By Jennine Barrett - Published on Amazon.com
Format:Paperback|Verified Purchase
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.
