Read Alouds are a great way to bring new topics to the table. This video is the song version of the book, Don't Laugh at Me, by Steve Seskin. It is great to use if your library does not have a hard copy of the book.
If you are looking for a resource that your school may already take advantage of, BrainPop is it. This video goes over bullying and, like all of their videos, has discussion questions and a quiz at the end.
