#spiral-bound This book gives explicit examples of how to use manipulatives to foster the learning of math concepts. The lessons are clearly and concisely written for easy implementation. Each lesson uses manipulatives that are typically found in schools so that no additional cost should be needed to purchase materials. After each lesson, there is a section called “Mathematical Potential “ in which the author clearly explains how the lesson can be extended to a deeper level (and/or higher grade level). The book is 88 pages in length and comes in a three ring binder.
