Fun with shadow puppets! You can do these with kids of all ages. I did them with two and three year olds. While the cognitive ability to figure out the idea of the shadow, etc, was very different, everyone still had fun doing them.
Rewarding kids with things they get to do instead of things they get to have. When they do something good, they pick from the jar and get things like to stay up a little later or play outside a little longer etc. Cute idea!-
