Highly rated and a bestseller in children’s educational books, it encourages early STEM learning and family engagement with a timeless, multi-layered narrative. ## Description 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. Review: Excellent early math exposure - I'm a Devotee of Susan Wise Bauer and this was one of the many wonderful choices she recommends in her book The Well Trained Mind. I've read the Story Of The World by Bauer to my kindergartner and she has a huge thirst for history. Her first comment was, "Pythagoras? That name sounds Greek." I owe that kind of thought process to Susan Wise Bauer. I would encourage parents of young children not to underestimate the things that they can understand and remember. Be bold! Pass up the potato chip brain food that is Dora the Explorer and introduce your small children to history and science and art and math. You will be amazed and delighted by the pleasure they find in it when you make it regularly available to them. There is plenty in this book that my six-year-old doesn't quite grasp yet, but she is very keen on the story of a boy who appears about her age and is doing all sorts of interesting and clever things with math. Everything you introduce to your young child's brain is Velcro ready for more information to attach to it. Review: Useful - This story would be better if it spent a little more time on clarifying the idea of ratio and a little less on trying to be amusing, but I really appreciate all the Charlesbridge mathematic adventures, for being many-layered and classic - you can return to them again and again and get something different and valuable out every time, adding more strands to your understanding of the topic. They work for adults also, so they are very good family read-alouds. ## Features - Charlesbridge Publishing ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #121,718 in Books ( See Top 100 in Books ) #9 in Children's Books on Musical Instruments #149 in Children's Books on Ancient History #524 in Children's Books on Math | | Customer Reviews | 4.8 out of 5 stars 130 Reviews | ## Images ![Pythagoras and the Ratios: A Math Adventure (Charlesbridge Math Adventures) - Image 1](https://m.media-amazon.com/images/I/910PsqWiseL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent early math exposure *by S***E on 16 February 2015* I'm a Devotee of Susan Wise Bauer and this was one of the many wonderful choices she recommends in her book The Well Trained Mind.
