Pete is at a new school and he is somewhat of a bully. Luckily he is in a classroom with students that know how to handle situations with a bully. They learned how to handle bully situations from what went on in 2nd grade ("Spaghetti in a Hotdog Bun"). The teacher and the students have made "The Promise" to not be a bully and to not be a bystander when someone is being a bully. Pete continues to be a bully even after the students share with him "The Promise" that they all have made in their class. He makes a girl named Ruby really mad when he poured his juice box all over her shirt. Ruby get really mad and decides to forget about "The Promise" and she tries to get the rest of the class to do the same. Her classmates choose to not be bystanders and stick to their promise. This is shocking to Pete that someone would stick up for him after he was so mean. This is a great book for K-5th grade. It teaches students that being a bully does not work, but sticking together and helping others out is always the best way to go. I would have 1st-3rd grade students do a character analysis before and after with this book and "Spaghetti in a Hotdog Bun". This will helps students have a better understanding of how "The Promise" changed the students and why they came up with "The Promise".
