This book is a great book for students in 1st or 2nd grade. It is easy to read, and the math that is done in the book is at the right level for students in grades 1 or 2. The story is interesting as well, and the students would find it engaging. One other reason I think students would love this book is because they can relate to it, and the main character is the same age as the students. I would use this book as a read aloud for the whole class. I would relate it to math, because that is what it is about. It would also be fun to have students bring in their own collections after reading this book. The math unit I would focus on with this book is addition. The addition that is done in the book is simple, yet could be challenging enough for the kids reading the book. This book has images that the students would love, and images that a teacher would like as well. They are all accurate in the amount of items each collection has. This books math is accurate, and the way it is presented is direct. After reading this book, I think students may be more interested in math, or at least realize that they use math in their everyday lives.
