Absolutely. I am an "algorithm" person. I can follow directions, follow a formula, but have little understanding of the "why" behind the math. Reading that book was like a giant light bulb. Now I am looking further into it both for my kids at home and for students at work. My school is about half asian and half westerners but my teachers are ALL westerners and teach american-style, algorithm-only math. That needs to change.I am thinking of getting copies of this book for all my teachers and using it for PD. But then I want to get a good curriculum to use at home for my boys (and look into one that could be used in a classroom setting for my students).
This book should be required reading for all elementary teachers!
