This is an excellent book that I love! I would want to read this from kindergarten to firth grade. Keeping it in my book library if I had first or second grade. This book would be prefect for the beginning of the school year to show kids how they should and should not behave. Also after reading this book you could come up with a similar deal for your classroom. Then if one of your students is being mean to another you can remind them of their promise.
