I have started a Points System for my children in which if they collect 100 points they can buy a toy of up to $20. These are two reasons to start this thing.
1) Children to help mom in doing household things such as cleaning, cooking, gardening etc.
2) They start valuing money
For helping mom in kichen children get 5 points. If they clean their rooms they get 10 points, so on and so forth.
Although, its helping me in getting children disciplined, but they still do not value money as much as I want them to be. I will be interested to know what other Topbargains members are doing to make children smart about money.
