This book is fun, easy to read, engaging, and catchy. I would definitely use this book to read aloud to my class, at the beginning of the year in grades k-3. After reading it out loud, of course, I would keep it in my classroom library. 

"Pete the Cat too Cool for School" contains a great moral: "If you want to be cool, just be you!". This would be a great book for the beginning of the year. After reading, students could complete an activity writing and presenting to the class how they are cool, giving details about themselves.

This book would be great for a social skills lesson on sharing and making new friends. Great for beginning of school year.In the story Llama meets Gnu girl, he has to learn to share with Gnu girl and to find something to play together that meets both of their different interests. 

The text also rhymes throughout the story, this book could be used to reinforce different word families.
