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!
Angie - I feel you and Jesse should see this! I'VE BEEN DOING IT WRONG SINCE CHILDHOOD. Genius. Though it's worth noting you should probably clean out your couch first, or put something down on the seat of the couch. Nobody wants crumbs in their knees.
