Review title: changes the way you view math
Product review: Excellent book for anyone interested in math. This should be mandatory reading for all future and current teachers! I see math in a new light. This book will inspire you to re-evaluate your own knowledge of elementary math, and to work from a procedural understanding of math to conceptual.
