This inventive illustrated book uses the metaphor of a train to teach the basic conventions of conversation to children with autism spectrum disorders (ASDs). Engines are like greetings; they get the train moving. Freight cars are like the different "turns" of speakers; it's good to have at least a few during a conversation. A set of points guides a train from one track to another and resembles a subtle change of subject in conversation. When a conversation veers off topic, it's like a train that's derailed. In addition to the engaging color photographs of trains, the book also contains interesting photocopiable worksheets and coloring pages to help promote the generalization of skills. This visually rich approach to conversation is ideally suited for children with ASDs aged approximately 5-13 years.
