This distracts from the escalating verbal aspect of the situation and may give him a more socially acceptable way of expressing frustration or anxiety. Another alternative is role-playing the repetitive argument or question with you taking his part and having him answer you as he thinks you might. Since these individuals experience various communication difficulties, do not rely on students with autism to relay important messages to their parents about school events, assignments, school rules, etc., unless you try it on an experimental basis with follow-up or unless you are already certain that the student has mastered this skill. Even sending home a note for his parents may not work. The student may not remember to deliver the note or may lose it before reaching home.
Phone calls to parents work best until the skill can be developed.
If your class involves pairing off or choosing partners, either draw numbers or use some other arbitrary means of pairing. Or ask an especially kind student if he or she would agree to choose the individual with autism as a partner before the pairing takes place. The student with autism is most often the individual left with no partner. This is unfortunate since these students could benefit most from having a partner. Assume nothing when assessing skills.
