The chore system we used at our old house (Punch Cards) just hasn't been working for us since we moved. So, we recently made new chore charts and they've been a HIT with the boys! It's really just a different way of keeping track of what needs to be done and tallying all those check marks for what we call "The Reward Basket". John keeps little goodies in there that the boys can shop for with their chore points. It's been a great incentive! At one point there was a question about whether we should reward chores, but we are seeing the boys' work ethic growing quite a bit, so we think it's working well! Besides, positive reinforcements are much more pleasant for everyone than the negative kind. :)
I really love seeing them get excited to mark a chore completed!
