This lesson accompanies the story "The Day the Monster Came to School." This not a book you can buy, but a story that I found just by googling the title. I read this book on the first day of school to my preschoolers, and it is a huge hit. After reading the story, we talk about rules and what rules we should have in our classroom. Then, each student colors a monster and tells me a rule to write down on the monster's stomach. We hang the monsters up in the classroom for the entire school year. It's fun to see the students refer to the monster rules throughout the year.
