This book is so good and important that I read it in two days and wrote the song in a few hours! The beat is similar to the Black Eyed Peas song "Where is the Love" and I think students will enjoy rapping and singing. It sounds like a song that could be on the radio or itunes now.
The song includes a Choose Kind exercise where students have to pick someone they don't normally talk to and face them, smile, keep eye contact while the Star Wars Theme plays (just a few measures) and give them a compliment.
I also include a lyric sheet if you have a smartboard it would work nicely, along with several creative writing activities such as: reflecting on how they can choose kind; is there a character they would want to write a chapter about; has there been an event that inspired them to write a story like RJ Palacio had when she encountered the little girl with a similar difference as Auggie?
They can also draw themselves as an animal like in the book.
