That gives the kids "some" exercise.


The kids can work in groups standing around the edge of the room,
working together at the "board" for instance (you suggested this was a
math class).
Keep them out of their chairs!!! What do they need chairs for? Perhaps
let them return to their chairs as a "reward" for finishing their work
(but you
do not wish to turn it into a race!) I think it works best if you
arrange the groups to consist of students of balanced ability--otherwise
the weakest and the strongest
students seem to end up in the same group. The idea is for the strong
students to help the weaker ones. BTDT.
