My boys are 4 and 6 and are obsessed with all things Star Wars. They haven't seen the movies yet and they are full of questions about the characters. This book is perfect to introduce them to the characters and their strengths and weaknesses. It has also been very helpful to me since my memory of the Star Wars movies is a bit hazy and they ask very specific questions. It rates each character's strengths in various categories and then you guess who you think will win the battle. Then you look in the back to find out the answer. It shows their ratings in graph form which translates perfectly to my kindergarteners math lessons. We read several of the matchups each night and they never get tired of them.
