Elementary & Middle School Mathematics: Teaching Developmentally, 5th edition

This book has always been more than a textbook. It is resource for teaching mathematics. If you are taking a course, you will almost certainly not "cover" the entire book. However, whether you are now in a course or are currently teaching, I think you will find that the book will be a well-used reference. The chapters are separated into two distinct sections. The first section of eight chapters deals with important ideas that cross the boundaries of specific areas of content. The second section of 16 chapters offers teaching suggestions for every major topic in the K-8 curriculum.
