Sara,
At age 6, my kids get $2.50 per month (not week) - $2 to keep, 25 cents tithing, 25 cents savings. I don't tell them how they can or can't spend their money that is to keep. It's theirs. I never buy them anything from the store - no candy, no toys, nothing. Gifts are for Christmas and birthdays. I think it is a really bad idea to give children things on a regular basis without them earning it. It sets up bad habits, a poor parent/child relationship and sends an unrealistic message about the real world that doesn't prepare them to be self-reliant adults.
Here's our chore chart for that age...
Morning routine -
Say prayers, get dressed, make bed, dirty laundry to basket, make breakfast, clear your dishes, dust buster the crumbs under the table, unload silverware and plastic plates, bowls and cups from dishwasher, fold clean clothes and put in dressers, brush teeth and hair, clean room, load backpack for school.
Evening routine -
Pick up toys, set table for dinner, clear table after dinner, dust buster under the table, make lunch for school, homework (or reading,) shower, put on pajamas and dirty laundry to basket, say prayers before bed.
We don't pay money for chores, but they earn "screen time" tickets when they do them. Each chore done without reminder equals 2 tickets (or minutes) in front of the computer or TV. 1 reminder means 1 ticket, 2 reminders means no tickets. If they did everything without any reminders, they would earn 30-40 minutes of screen time a day. They can spend it daily when all chores are done or save up for a few days to watch a Disney movie. (A religious children's cartoon on Sunday or family dates to the movie theatre don't cost tickets.)
I made my own chart out of construction paper and drew a little picture next to the words for my littlest boy who can't read. There is a pocket next to each chore to put the tickets in. When I get around to it, I want to get one of those hanging vinal sheets with all of the pockets in it. Then they can use index cards for their tickets and keep track of it that way.
When they ask if they can watch TV or get on the computer I ask, "Is your chart done? Do you have enough tickets?" They count their tickets, pay them and set the kitchen timer so they know when to turn off the screen. They are also responsible for paying themselves tickets when they do their chores. I keep an eye on it and am proud to say that they are so honest in their dealings with the chore chart.
If they want extra cash, they can earn it by doing some of mom and dad's jobs. And sometimes we just ask them to help us out so we have time to do more things with them. They help us with picking up leaves in the yard, weeding the garden and flowers, vacuuming, dusting, wiping mirrors and windows, helping wash the car, sorting laundry and starting the washer and dryer, etc.
Whatever you do, I think the important thing is to send the message that your family is a team and every member is needed. No one gets a free ride and everyone's contribution is important. I am straight with my kids about how much I need their help with the housework and how I couldn't do it all alone. Children don't need to be coddled, they need to feel like a contributor. I also help them see that the more they help me get done, the more time and energy I have to play with them.
Good luck,
S.
