What Is a Bank?
A bank is a business that provides services that help people manage their money.
What does a bank do?
Mostly electronic, not a big safe
It's tempting to picture a bank as a giant vault holding physical cash. In reality, modern banking is mostly electronic — your money is recorded as numbers in a system, not stacked as notes in a room. For younger children though, it's easiest to start with the familiar idea of simply keeping money somewhere safe.
From jar to bank
When you're little
You might keep your savings in a jar, where you can see and count the exact coins.
As you get older
You might keep your savings in a bank account instead.
Your money becomes recorded electronically, rather than being physically stored as the exact coins you deposited.
Bank accounts
People keep their money with a bank in an account. An account keeps track of money coming in, money going out, and how much is currently available. We'll look much closer at how an account actually works in the next lesson, What Is a Bank Account?
Banks and money
Banks don't just store money. They provide services that let people and businesses save, pay, receive money, and borrow. Borrowing is a much bigger topic we'll come back to later — for now, it's enough to know that banks can help with that too.
Getting paid $20
Where would you keep $100?
A jar, a bank account, or some of each? What matters to you?
Think about safety, being able to see how much you have, easy access when you want to spend it, and how it might grow if you're saving. There's no single "correct" answer — different things matter to different people.
This is a great moment to explain how your own family uses banks — how money arrives in an account and how payments leave it. There's no need to share sensitive banking details with your child; the goal is just to make the everyday process visible.
Banks usually offer different kinds of accounts — a transaction account for everyday spending, and a savings account for money you're putting aside. Some accounts pay you a small amount of interest, and banks can charge interest on some kinds of borrowing. Many people manage all of this through online banking rather than visiting a branch. We'll cover interest properly in a later lesson.
