This book is great; it not only teaches the life cycle of a butterfly, counting to 5, the names of the days of the week, but also about different types of food. The actual holes in the book create an intriguing imaginative picture of how the caterpillar munches his way through food. The easy-to-read words makes good teaching tool for younger children (preschool or younger). I also read this book in Spanish and I recommend it 100× more than this eng. version.
