I wrote this suggestion to another question on this forum, but it could be helpful in a number of different situations, so I'm re-posting it as a separate message.
I read a wonderful book that was being passed around by the parents at a special ed meeting, "Tales from Time-Out" by Dr. Henry Roth. He runs a school for kids who have emotional and behavior problems, elementary through high school. It is illustrated with cartoon drawings, but the stories and his discussions of the kids' problems is terrific.
