I've tried reward charts, tickets, fake money, marbles in a jar, you name it. It always seem to work wonderful for a month or so. Then it starts to get tedious and it doesn't work so well after the novelty wears off. Suddenly the reward that worked so well doesn't seem so appealing, or it's time for a reward and it doesn't work with our schedule. We'd also forget to mark chores off when we were in a hurry. We had trouble keeping track of marbles in the jar (one time the cat knocked the jar off the counter and broke it and the hard-earned marbles went everywhere!) and the fake money seemed to get lost.
The easiest system for us was a Control Journal for my daughter. We have a page for each day and her routines for that day are listed. Her chores are also listed as well. Each page is in a plastic sleeve and put in a binder. She uses a wet-erase marker to cross off her duties as she does them. This is her responsibility, not ours. (she is 9)
At the end of the week on Allowance day we review her journal. She is awarded $1.00 per day for completing all her tasks. If all of her tasks are not complete for that day, she earns nothing.
Now, you may not want to do that part, you may want to pay for partial tasks. However, we did that system for a while and she'd do maybe 50% of her chores and then she'd say "well, I did SOME of them" and act as if the rest didn't matter. She knew she'd get some money for that day so she didn't care. She's older now, so she knows that cleaning 1/2 of the bathroom is not okay. In the real working world, if you do 50% of your job you get fired.
This has worked for us and is easier for everyone than charts and tickets.
I also want to mention the House Fairy. This worked for helping her keep her room clean! Check out the website www.housefairy.org. You don't have to join to have the house fairy visit. She comes unexpectedly, so you never know! She comes to see if little children's bedrooms are clean. If they are, she leaves a surprise. If it is not, she leaves fairy dust. This worked wonderful for a long time as you do not have to have a chart. Every night they need to make sure their bedroom is clean just in case she shows up! (Our house fairy came once a week but you never knew which day and she shopped the dollar aisles at Target for surprises).
My daughter no longer believes in the House Fairy :( but it worked for many years. If your children are young, they will love the house fairy!
