String, Straightedge and Shadow - The Story of Geometry by Julia E. Diggins is one of the books we are reading in order to learn high school geometry. The conversational style and clear illustrations as well as the historical background help to make geometry come alive. We are using it in conjunction with Patty Paper Geometryby Michael Serraand an online site, Learning Math: Geometry, an online, interactive Geometry Course. We have found many videos on YouTube to reinforce the new vocabulary ter ...more

The path to discovery by early civilizations is fascinating. I really enjoyed this book which begins with the discovery of the circle and ends with a synopsis of Euclid's famous book Elements. I was amazed that the pyramids and the Parthenon were built with no more technology than a string and an understanding of the 3-4-5 triangle. The well constructed narrative brings these people and their excitement over these discoveries to life. I learned about the patterns in math from a new perspective a ...more
An accessible history of ancient geometry, aimed at older elementary or junior high students. The premise of the book--that all early geometry is based upon the three titular objects--necessarily keeps the text simple to follow. The sections on the Greeks, supplemented with clear diagrams and simply explained proofs of basic geometric theorems, are fascinating. Sections on earlier "prehistoric" and even Egyptian geometry are less so both because they lack detailed content and because they repeat ...more
This gem is about ancient Geometry that has definite application today. Knowing the stories behind many great discoveries make them so much more interesting and really helps math to come alive. I highly recommend and have already started sharing he stories with even my youngest kiddos.

I did learn from reading this book but I was highly frustrated by the leaps and suppositions that this author chose to make. I do realize that some suppositions have to be made when trying to tell a story from prehistoric times, but she seemed to be too open to making huge leaps that made me uncomfortable. This was good for my boys to read and get a feel for the importance of geometry. I would recommend it for that purpose.
Her writing captivated me from the beginning paragraph. This is a wonderful book, well worth the read!
I'm definitely having my kids read this for learning geometry. It is a story of the history of geometry and the famous people and philosophers in their probable situations and observations. I love the context for learning and tying everything into historic progression. Fun to follow along in historic progress and try the same observations and experiments as a class.
Pitiful attempt to make learning into a story. You could tell that they were trying to but just didn't work out at all. Baaaaaad!

They say, "This engrossing book will captivate you and hold you breathless on the edge of your seat from the first page to the end" NOOOOOT!
So I got made fun of reading this book during a family camping trip, but hey, I can't help it, I LOVE math! :) The caveman stuff was pretty lame, but I loved reading about the history of why we now have geometry.
This book started off a bit dull. But as it progressed, it was so interesting to read about the history of geometry.
A good look at this history of Math and Geometry This book has been flawed due to evolutionary content.
Great, great, history of geography for a child.
