I always give the teachers the first 6 weeks to get to know my kids before I throw myself into the situation, if at all possible. My kids have always been in slightly crowded schools, so I figured it takes awhile to actually get to know 20-25 kids.
At that age I reminded them the first month or so of school is basically just play time! There will be lots of playing games, singing songs, learning about the rules in the classroom, meeting all your teachers, and maybe doing a bit of schoolwork so your teacher can see what you remember. It never seems like they get around to serious classwork until nearly halloween.
