Having read this book when I was in fifth grade, I would have to say that it is a Halloween favorite. Not only does it promote being different, but it also is just a fun read that practically any student would enjoy. With that in mind, I would definitely use this book with students in kindergarten all the way to sixth grade. For the younger grades, kindergarten to second, after reading the book I would have them draw their own pumpkin. I would stress that it could be any shape, color, and size they wanted. Then I would have them write one thing on the pumpkin that they think makes them different. Once everyone had completed their pumpkin, I would allow the students to share and then hang them up in the hall for the school to see.
When it come to the older grades, third through sixth, I would use this and other Halloween picture books to work on summarizing. What I mean is that towards the beginning of the month of October, I would have each of my students read one Halloween picture book. Then on a strip of paper, they would have to write a summary of the book, which they would then slide in a brown paper bag they had decorated. Once everyone's was complete, I would have them share their summaries. After they shared I would use the completed projects in a cute bulletin board for the remainder of the month.
