This is a story about an unlikely friendship between a spider and a pig. Wilbur and Charlotte become the best of friends after Charlotte begins to write letters in her web, drawing an incredible amount of attention to Wilbur. Using this story as a way to introduce diversity is a great idea. This will help students understand that although everyone is different, there is a way to celebrate those differences. Have students come up with three words of their own to describe someone else in the class, and this could be used as a self esteem exercise in the class as well.
