When I was in 3rd grade, the assistant teacher Mrs. Ware started off the reading of this book by asking generally if anyone had ever been spanked for being late. I was definitely a spank-o by that time, because I enjoyed every minute of that discussion and the story that followed.
Be sure to read "Ping"
The Robert Newton Peck book "Soup and Me" was read aloud two years later and I thoughly enjoyed it too, espcecially the first chapter.
