This lesson focuses on What Money Is: learn what money is and why everyone agrees to accept it.
Learn what money is and why everyone agrees to accept it.
Key ideas
Why money exists
Long ago people bartered, swapping goods directly, but barter needs both people to want what the other offers. Money solved this: everyone accepts it, it divides into small amounts, and it keeps its value. That is why a £5 note is useful even though the paper itself is nearly worthless.
How we pay today
Cash is notes and coins you can hold. Most adults also pay with debit cards, phones or online banking, which move money electronically. However the money moves, the idea is identical: you give up some of your money to get something you want.
Key term — barter: Exchanging goods or services directly without money, such as swapping a toy for a book. It only works if each person wants what the other offers.
Why do people trust a £10 note?
