Bud, Not Buddy is a story about an orphaned boy who runs away to find who he believes is his father. The plot follows his journey through northern Michigan during the 1930's. Bud faces many challenges, and overcomes all of them. I would use this book for upper grades, probably around fourth and fifth grade. It could be tied in with a history lesson, the students could learn about how life was during the 1930's while reading the novel. It could also be a writing lesson in which the students write to Bud, or write their own extension of the story itself.
