OH MY WORD! This book is so much fun! I have only known about Pete the Cat for a few months and I knew book after I heard about the series. Pete the Cat is ready to go outside and enjoy his day when all of a sudden, one of his buttons pops off! Pete the Cat loses all of his buttons throughout the book but then realizes he has a button that he forgot he had! This book incorporates math while reading. Each time Pete loses a button, they show a math equation to represent what just happened to his buttons. For example, Pete begins his day with 4 buttons and when the first button pops off, there is a page specifically for the math equation. It will say 4-1=3! I would show this book off by having a students dress up in a yellow jacket with 4 buttons tapped to the jacket and each time Pete loses a button in the book, I would have the student take a button off the jacket. This way, the book can come alive for those students. This book is for kindergarten or first grade. The level of the book is 2.0
