The author's beautiful drawings illustrate basic concepts of mathematics and stimulate a child's curiosity. Parents will want to refer to this book often and in this way they and their children will learn and, most importantly, REMEMBER what they can so easily visualize. If I had had this teaching aid in High School I would have remembered so much more of my lessons. If my teachers had used this book, they would have had much greater success in teaching their students. The author also has two other books in this series, "20 Napkins of Physics" and 20 Napkins of Chemistry."Was this review helpful? Yes NoThank you for your feedback.
