Is the move to a completely new teacher/class all day and he's not having the original one at all? (confused what you mean by Split)

My kids have split classes where they have a "main" teacher but for math they might have a different teacher and reading they'll have their "main" teacher. Typically they have one teacher for math & science and another for reading & social studies. They do seem to divide the kids up so most are on the same "level".

So didn't know if it's like that or if he's just moved into a completely different classroom/teacher.

I think when you don't have the chance to prepare them, it's harder to deal with the adjustment. The school really needed to let you know in advance that this was going to happen.
