My son found a cute artistic check on the ground at the supermarket the other day. He was so excited because he thought it was money. I told him the right thing to do is to turn in the check or just rip it up and throw it away. I started getting into how to handle a bank account and what you need to do with your checks to keep them safe. He was really interested in learning about money and how to write checks so when he was old enough to have an account he could do it right.
