Another great Mrs.Gilmore suggestion :) Moon Blake has lived out in the woods since he was 2 years old with his dad. When his dad falls ill and dies, Moon is left to fend for himself. With a crazy constable on his tail, Moon gets sent to a boys home and then breaks out with 2 friends, Hal and Kip. Another survivalist tale but so much more than living in the woods. It focuses on forming friendships and family dynamics, such a great story for upper grades. It would be a great literature circle book but also class study. There is some profanity so you may need to get that cleared with your parents but it is a great story! I would like to watch the movie adaptation and see how it compares, which could also be a good way to close out the study of the book in your classroom.
