When we first tried this, I went first to start things rolling. I asked a student what their favorite color was and then gave the visual supports so that he could answer.
After the student answered, a silent prompter pointed to the visual cue with the question "Mrs. Shamberger, what is your favorite color?" The student then asked me the question.
We had to work a lot on the students looking toward each other when they asked and answered the questions. Since we started working on this about a month and a half ago, we have started to take the visuals away. The students are now looking at each other, using their names to get attention, and then asking questions without the visuals! It has been a great activity to use with our students with ASD that are in self-contained classrooms.
