I love this book!! I recently read this to my class I observe in. It has a reading level of a 3.5. It is a great story about a boy who is reluctant to spend the summer at his grandma's river house, but finds a raft and ends up having a wonderful summer on the river with his grandma. We could use it in the classroom to talk about how the character changes in the story. We could focus on this lesson of character development.
