Thanks for the great ideas.

I have done similar to what you suggested, bingding, but have usually broken them up into groups and then had any 'offenders' sit out the reward.

I carry antiperspirant for the sweat! It gets hot in those classrooms and I can never figure out the thermostat! I also do a lot of standing Yoga... they have no idea that I'm doing it either.

I work with Kindergarten - Fifth Grade. There are 5 elementary schools in our area but I only work at the one where my son is.
