This is a hilarious book about a boy and his brother. They encounter many trials and tribulations. I would use this book with 3rd, 4th, and 5th graders. I would use it as a read aloud or in Literature Circles. Students with siblings would find this text easy to relate to. I would use this text as my students were studying compare/contrast. It would lend itself nicely for students to compare/contrast their lives to Peter or Fudge, two of the main characters in the story.
