When I purchase materials for our professional collection, I try to read them. I was intimidated by this book because I have always felt I do not have a math brain. My oldest daughter is a math teacher, and I realized that I, like too many of us, say, "I'm not good at math." As an English teacher, I would never accept the same comments from a student about English, so why should I deem it suitable to speak this way about math? So, I set aside my hesitations, and I read this book.
It's actually easy to read and provides lots of research. I've read many books and articles about brain based learning, and this book applies all of that to how we should teach math for optimal learning. The author provides specific examples and instructions for how to teach. I think the book is more relevant for elementary schools than high schools, but I still recommend high school teachers to read this.
In a world of high stakes testing and companies that are creating new programs every year for English and Math, this book shows that it's not so much what we teach but how and when we teach it and why.
