The Complete Adventure of Curious George
These are a series of books involving "George" who is a monkey living with a man in a yellow hat. George is always curious and that curiosity always causes him to get into trouble but not so much that he can't learn a lesson from it!
Any grade up to 2nd i should say is good for this book series. I would most likely use it to plan a series of lessons involving following the rules and doing what you are supposed to. Most likely at the very beginning of the year.
