Blessings Jar

We have, well my wife has, come up with this really neat idea. First you buy some marbles or take them out of your Chinese Checkers game. Then you take a quart jar and as your children bless each other they get to put a marble in the jar. You explain to them what a blessing is or how they can bless other people. Being cheerful, helpful, nice to their siblings, and a whole host of other things. You also explain to them that they will not get to put a marble in the jar every time they bless some one. You need to bless all the time even when you are not rewarded for it. After the jar is full we will go do some thing special as a family.
