Some people go to a bank, and some people keep their money at home. But lots of smart people go to a credit union. Credit unions are different from banks primarily in the fact that they are not-for-profit. That means that as a member you often get better interest rates, so your money grows faster. Only some people can join a credit union. Usually you have to belong to a special group, live in a certain area, or work at a certain place - or be related to someone who does (like your dad or mom).

The money you put in your savings earns money because the credit union lets another member borrow it. The member who borrows it pays the credit union "interest" for the use of the money. In return, the credit union pays you dividends for the use of your money.
