I work for the Boone HSAP - So I teach a variety of classes K-12. The one class is K-2 enrichment. I could start teaching financial literacy by setting up a fake store and giving the children fake money to buy things in that store (of course grade and ability considered). This will start to make children aware that if they don't have the money for something they can't buy it. This could be great going forward in teaching them to stay out of debt.
