Geometry, of all the branches of mathematics, is the one that is most easily visualized by making something. However, it is all too easy to reduce it to reams of formulas to memorize and proofs to replicate. This book aims to take geometry back to its practical roots with 3D printed models and puzzles as well as demonstrations with household objects like flashlights and paper towel tubes.
This is not a traditional geometry textbook, but rather builds up understanding of geometry concepts while also bringing in elements of concepts normally learned much later. Some of the models are counterintuitive, and figuring out how and why they work will both entertain and give insights. Two final chapters suggesting open-ended projects in astronomy and physics, and art and architecture, allow for deeper understanding and integration of the learning in the rest of the book.

Great resource for my granddaughter.
Liviu Dan Serban –
This book helped me to remember and fix in my memory many of the math concepts learned more than 15 years ago. I recommend this book to anyone who wants to learn complicated geometry notions in a logical way with examples from common objects and printed models
William F. Adams –
Highly recommended for anyone who wishes to learn more about geometry, or to improve their skills at using it in a practical fashion.

Well organized, decorated, and fun. I can’t wait to get the other ones.
