Social Signals ($159.oo) is a series of videos and curriculum are designed to teach adolescent students with autism and intellectual disability about safe relationship skills. There is also a parent curriculum for $23.99. They have a sample video and lesson available for free so you can preview before you purchase. I liked the video. I like to teach about expected and unexpected behaviors and I think these videos could be a good tool. There are also sample lessons that accompany the videos.
