Communication Any Way simply means acceptance and responding immediately to a clear communicative intent by a student.
I have a student who uses a communication book. At times he will just point to an item on the snack table instead of using his book in response to a question. Sometimes he will indicate yes or no with a headshake instead of using his book. We keep prompting but then he becomes frustrated and displays other behaviors such as throwing materials or yelling. How can we increase his communication book usage?
