There are so many books and other resources for understanding and developing social skills, and I have to admit that I have not read much in this area yet. So I am actually looking for recommendations on what people have found helpful, especially as their kids were entering elementary school.
The biggest resource I personally have used so far in this area is Social Stories ™ by Carol Gray, and I can’t even begin to tell you how helpful they have been. Once you learn the guidelines for writing them, you can easily create one for any situation. Visit The Gray Center for Social Learning and Understanding to find information on these, as well as a variety of related topics, such as adolescence and bullying.
At the Penn State Autism Conference last year, Dr. Scott Bellini from the Indiana Resource Center for Autism presented on Building Social Relationships. It was a fascinating workshop, despite the fact that there was a fire drill in the middle of it (many of us thought he was trying to give an example of sensory overload, but it was real)! The IRCA website also has in-depth articles on a wide range of topics, including several contributed by Temple Grandin.
