Identify the special need(s) that the child might be exhibiting. What would you do to help the child? Use a resource room? Inclusion? Be specific. CASE 2-PETER Peter is 9 and is a relatively new pupil to the school, having been expelled from his previous one due to extreme behavior problems. He has quite severe dyslexia and as a result becomes extremely emotional and frustrated when asked to do something which is difficult for him. On one occasion Peter and his ‘girlfriend’ were found hugging and kissing. This behavior was considered inappropriate by the school and he was taken into the principal’s office to be told so. Peter’s reaction was rage and he began to throw chairs, kick and punch the adults around him and throw his head against the walls. On another occasion a new child joined the class. Peter took offense at the new child looking at him and flew into a temper putting his head through the mobile classroom wall.
