Ditto our experience, kimck. The smarter the kid in the 1st grade class, the more likely the child was to lose recess time and the less recess time the child was allowed when s/he actually got some. So the behavior problems were the kids' problems? Or d'ya think maybe the teacher had some issues with GT kids?
Yeah, that's what I thought, too.

K was a breeze by comparison. The K teacher differentiated the work and tried to teach every child, regardless of what they came in knowing. The 1st grade teacher bored the fool out of the bright kids and then tried to punish/bribe them to good behavior.
I think the behavioral *expectations* for K and 1st grade were similar, but I think our K teacher did a much better job of managing the classroom, so she actually got better behavior out of the younger kids.
I guess the biggest difference I saw was that our K class was only half a day, while 1st was all day. So the K kids only had to control themselves using "school behavior" for 3.5 hours instead of 7 hours or so. Otherwise, both the K and the 1st grade teachers expected kids to raise hands and be called on before speaking, sit still and listen when spoken to, stay in seats unless asked to get out, etc.
