For the break, we did a "Brain Gym" workout I found on YouTube. Brain Gym is a series of exercises used by practitioners of Accelerated Learning. They're supposed to activate brain areas and give you exercise at the same time (which is also good for thinking skills).
This week I'll follow a similar program, since things went pretty well. Regarding my prize box, initially prizes were supposed to be for once they get 10 stars, but the little kids were getting left out, so I let them all choose something for effort. When they're gone, I think I'll just stick with stars for accomplishing levels. I should have some help tomorrow as well from one of the dads.
