Kids love video games. If you can make something seem like a video game, kids eat it up. This is the perfect example. When Pacman eats a cherry, he gets 200 extra points. If he eats a ghost, he gets 500 points. It all makes sense. I don't know why I'm using a video game that kids haven't played in decades, but who doesn't love Pacman? By applying points to chores, kids not only have goals, but they understand the importance of different tasks. Maybe if I use this on myself I will actually do my chores.
I'd be the kid who tries to calculate how to do the least amount of work for the most point value. I'd be done with all five hundred points within an hour. I was always a schemer like that.
