For the past 4 years I have taught students who have been suspended from school due to behavior problems. One in particular was in first grade and in my opinion never should have left Kindergarten. I am not sure if this will apply but what I have found is that often these students are struggling so much academically that they want to take the focus off that by misbehaving. My student only knew 2 sight words and could not add, this was in January when I got him. It took me several weeks before I got him to sit with me and learn. I would recommend the student be put in a class where he could get more one on one or at least small group instruction. Some parents don't want to hear the words "special education" but that doesn't mean the child would have to be in a special ed. class through out his school years but perhaps just to give him the help he needs now. I hope this helps.
