This is a great book that talks about aspects of the Great Depression. Bud Caldwell is an orphan who gets placed with a foster family and runs away. He meets up with a jazz band and later realizes his grandfather is in the band. I would use this book with my 5th grade class. I would use this book when talking about the Great Depression. This book is filled with tons of figurative language, so you could do a small group lesson on figurative language and use this book.
