A lot of people suggested sticker charts for good behavior, but I'm really not a chart person at all. I hate creating them and for some reason we always forget about them after a week. I like the idea of them though, because the kids actually get to see their progress, so instead of a chart I decided to go with jars that they can put glass stones in and still see how they are progressing.
I picked up these three jars from Michaels and unfortunately they were not on sale so I ended up paying five dollars a jar which I normally would never do. I was in such a hurry to get started with them though that I didn't want to wait. I also had to buy a bag of decorative stones for another six dollars, but the vinyl letters I already had at home so at least one part of them was free. I actually debated between the stones and something soft like those craft puff ball things, but since they are on top of the piano in our living room, I wanted something that could blend in as decor.
Even though it's only been a couple of days the jars are filling up pretty quickly. And the reward for getting the jars filled up is a date with Mom or Dad to get a doughnut, that way we can give lots of stones for good behavior and not worry about breaking the bank.
Thanks again for all your help!
