The Warm Fuzzies Jar

I found this idea today... The Warm Fuzzies Jar  And I really think I'm going out to get me some pompoms! I've tried something very similar with pennies, but then it's pennies, and I don't want to start paying the children to do well. I love the rewarding aspect this presents, as well as instant affirmation. Great Idea! Maybe somebody else will like it as well.
 Here is a direct quote of part of the article I've linked to above, but you can read the rest by following it:
"I went to the kitchen and found a large pickle jar and filled it with the colorful pom-pom balls. Then I set two smaller jars beside it on the kitchen counter. Within minutes, my children noticed the jars and inquired about them.
“This is The Warm Fuzzy Jar,” I explained. “Whenever you do something helpful or kind, you place a pom-pom ball in your designated jar because kind and helpful acts make people feel good, like a warm fuzzy.” The girls looked at each other with wide eyes and big smiles, so I continued. “And if you are doing something helpful together or just getting along nicely, you can put two pom-poms in your designated jar. And when your jar becomes full, you can choose something special for you and I to do together.”
My children had the same reaction as my former students did to filling The Warm Fuzzy jar—pure enthusiasm. They wasted no time being helpful.
They carried in groceries that I typically brought in by myself.
They put away shoes in the hallway that they used to step over for days.
They made their beds in the morning without being told … dirty clothes actually made it to the hamper without my help … dishes made it to the sink (and even got rinsed) with helpful smiles … musical instruments got played without reminders to practice.
There were even a few shockers like a surprise organization of my spice rack and a super clean toilet bowl. But that wasn’t all. The Warm Fuzzy Jar changed the atmosphere of our home. Cooperation and kindness seems to lighten everyone’s moods—most notably mine.
I noticed that she dressed herself and hung the discarded clothes back on hangers—not that the striped socks didn’t match the plaid skirt.
I noticed that she was helping her sister write sentences—not that the Sharpie she was using was turning her fingers black.
I noticed that she prepared a healthy breakfast of cereal and cantaloupe—not the trail of milk that went all the way from the counter to the kitchen table.
I noticed that she helped her sister do her hair—not the twelve barrettes that were secured haphazardly to the back of her head.
I was Noticing the Good, and it was making a huge difference in our day-to-day interactions and my children’s overall well-being."
