 How to Use This Book The book could be used as the framework for a discussion on "what equal means." The book could be used as a introduction for individual writing/drawing assignments with the prompt, "Describe or draw equal groups and explain why they are equal." The book could lead into a discussion of even numbers and the idea of "half." This book could help in a discussion of why 1/2 of one thing does not necessarily equal 1/2 of another thing. The book could also be used before an activity in which students are to divide into equal groups for various purposes: equal numbers on teams, equal heights, etc.
 Highlights and Insights This book clearly illustrates that, when we say two things are "equal," we must specify how they are equal. For example, two groups may be equal in number but not in weight. Too often we see "equal" as meaning "the same on both sides," as in an equation. This book makes us consider different circumstances, and therefore, different meanings of "equality."
