Author Julie Ellis and illustrator Phyllis Hornung Peacock team up once again to explore Pythagorean ratios in Pythagoras and the Ratios, the 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. Author: Julie Ellis Format: 32 pages, paperback Ages: 7-10 Publisher: Charlesbridge Publishing ISBN: 9781570917769

This review is from: Pythagoras and the Ratios: A Math Adventure (Paperback)
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 review is from: Pythagoras and the Ratios: A Math Adventure (Hardcover)
Um livrinho muito encantador. Ele ajuda a estabelecer relações entre a Aritmética e a Música (duas áreas da Matemática Antiga). E apresenta de modo simples o grande triunfo dos Pitagóricos que conseguiram modelar a harmonia musical por meio de relações numéricas... o que os levaria a acreditar que "Tudo É Número!".

Good on Pythagoras,

This review is from: Pythagoras and the Ratios: A Math Adventure (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.
