Ok..I had a great response from my chore charts so I wanted to give you a little more detail on how it works.
The Allowance hook holds the paper quarters that I down loaded from the internet. At the end of each day, if all the chore cards are on the done side, the children are given a quarter to place on their hook. At the end of the week we get out our envelopes(kept out of reach) and add up all of our money. At that time they can exchange currency. Like five dollars for a five dollar bill...buy the way, I use fake money I bought at Walmart for $1.29. It has enough in it for my four kiddos, but if you have five I would buy two packs. The kids love counting the money and exchanging it.
If they choose not to complete a chore, they do not recieve the quater for the day. It usually hits them when we are adding up at the end of the week and one has earned more than another. It is the perfect time to remind them that money is earned. I never make a big deal about a chore not being completed, I just give a reminder like, "Oh, that's sad, I guess you will not earn your quarter for the day. That's so sad."
