Arte, this was always going to be the problem with him when he started school. Unfortunately, he is going to have to learn that school doesn't move at his pace, and that he will have to adjust to the flow of school. I wouldn't be upset that he is the only one in his reading and maths 'group' - that shows that he's going to get work to his ability when they are doing maths and literacy activities. And of course he will be the only one in that group because no one else would even be close to where he is up to. It sounds to me like the reality of school has set in for him. he's never really spent this much time there in a formal school setting (remembering that kinder is nothing like school, even if they spend time there) and now the excitement has settled, he doesn't like it. The first few weeks, heck, even the first term of school for kids in their first year of school is pretty full on with assessing where all the kids are at and starting them off on their learning. I think his issues are going to be his undoing. He probably can't understand that school has a routine and that it changes often, and that being taught doesn't always mean having the teacher's undivided attention all the time and that learning has to be done at a pace that suits the majority of the class, not just him. I would talk to the teacher and maybe the Dr/OT (is that who is was?) and try to come up with some strategies for him to help him adjust to the change of pace and the routine of school. You know he's never been a kid that has adjusted easily to change and i can imagine that the regular changes in lessons and breaks etc would be getting to him. Ask his teacher if she can have some other type of activity for him as a 'fast finisher' so he can do that while she is helping the other kids finish their work. And I'd be following up on the principals gifted program as well.
