When my kids were younger, I would draw pictures for my grocery list and give half to each kid. This worked about two times. We are horrible around here about doing chores, etc. so I've come up with a similar sort of list to motivate the kids. I've done it a few times now, not every week, so it's still sort of unique and it seems to be working well.
I cut down the middle and hand half to each kid. They think it's great. And if they do them all, they get what ever increment of money I feel they deserve and I check off that they've been paid.
