We currently use marbles for behavior and obedience. If we ask the girls to do something and they do it right away they get a marble. (get jammies on, brush teeth, etc...) Or if they have been happy or kind to each other they get a marble, on the other hand if they are mean, unkind, don't do what they are asked or do it slow or with a bad attitude a marble is taken away. When their jar is filled to the line they get a reward of their choice. They have chosen things like going to build a bear, going swimming, a pottery studio and movies. It has been very effective. I can't take credit for this method, I copied it from my sister in law Emily, who I often go to for parenting advice.
So the tickets go something like this....You earn tickets for doing your assigned chores and any other work around the house. Then if you want to play with a friend, have a late over, watch a movie, watch tv, play the wii, computer etc... you have to pay with tickets. The best part of it all....it also teaches responsibility and honesty. The children are entirely in charge of their tickets. When the chore is complete they go to the bank bag and put the correct amount of tickets in their bag. When they want to watch a show they have to put the correct amount of tickets back in the bank bag. It has only been 4 days but it has been as effective as the marble jar. Maybe even more. I haven't heard I am bored for 4 days (a phrase that was said at least every twenty minutes) I hear things like what other jobs can I do? Have the dishes in the dishwasher been unloaded? Can I have some cleaner to wash the walls? Are there any clothes to fold?
