The Secret of Coins: Why We Use Money
Ages 3–9
Key Insight
Money is a 'medium of exchange' that everyone agrees has value. It solves the problem of 'double coincidence of wants,' making it easier to buy and sell anything.
📖 Explanation
🧒 For 3-5 Years Old
Imagine you have a toy car but you want an apple. If the boy with the apple doesn't want your car, you are stuck! Money is a magic token that everyone wants, so you can always get what you need.
🎒 For 6-9 Years Old
The Problem with Barter
Trading items directly is called Barter. It’s hard because you have to find someone who has exactly what you want AND wants exactly what you have. This is called the 'double coincidence of wants.'
Functions of Money
Money works because it is a Unit of Account (you can give things a price tag) and a Store of Value (you can save it for later, unlike a banana which will rot). Today, most money is digital, meaning it's just information stored in a bank's computer that we all trust!
❓ Frequently Asked Questions

- When there is too much money around or things become hard to make, the prices go up. This means your money can buy fewer things than before.
- Who prints the money?
