- [0](https://md.mova.elamur.ai/free/en/corpora/school/money/4-swaps-and-barter-in-the-playground/0/) — Barter is swapping things without using money, like two football cards for one Pokémon card in the playground.
- [1](https://md.mova.elamur.ai/free/en/corpora/school/money/4-swaps-and-barter-in-the-playground/1/) — A swap is good when both people freely agree and each values what they get more than what they give, like Ella's old scooter for her neighbour's skateboard: win-win.
- [3](https://md.mova.elamur.ai/free/en/corpora/school/money/4-swaps-and-barter-in-the-playground/3/) — A swap made with a threat is not a swap at all but bullying, and a "swap" where you give far more than you get is really a gift, so call it one if that is what you want.
- [4](https://md.mova.elamur.ai/free/en/corpora/school/money/4-swaps-and-barter-in-the-playground/4/) — Barter means swapping goods or help without using money.
- [5](https://md.mova.elamur.ai/free/en/corpora/school/money/4-swaps-and-barter-in-the-playground/5/) — Barter only works when each person has what the other wants; this is called a double coincidence of wants.
- [6](https://md.mova.elamur.ai/free/en/corpora/school/money/4-swaps-and-barter-in-the-playground/6/) — A fair swap is one both people agree to freely; forcing someone with a threat is bullying, not trading.
- [7](https://md.mova.elamur.ai/free/en/corpora/school/money/4-swaps-and-barter-in-the-playground/7/) — A good swap can leave both people happier, because each values the other's thing more; this is called win-win.
- [9](https://md.mova.elamur.ai/free/en/corpora/school/money/4-swaps-and-barter-in-the-playground/9/) — If one person knows much more about what things are worth, they can get the better deal, so find out values before you swap.
- [10](https://md.mova.elamur.ai/free/en/corpora/school/money/4-swaps-and-barter-in-the-playground/10/) — A gift is something you give for nothing back; a swap should be about equal value unless you mean it as a gift.
- [11](https://md.mova.elamur.ai/free/en/corpora/school/money/4-swaps-and-barter-in-the-playground/11/) — You can swap time and help as well as things, like neighbours who babysit for each other.
- [12](https://md.mova.elamur.ai/free/en/corpora/school/money/4-swaps-and-barter-in-the-playground/12/) — Many schools ban swapping food because some children have allergies, which can make them very ill.
- [13](https://md.mova.elamur.ai/free/en/corpora/school/money/4-swaps-and-barter-in-the-playground/13/) — Schools sometimes ban card swapping when it leads to fights or tricks.
- [14](https://md.mova.elamur.ai/free/en/corpora/school/money/4-swaps-and-barter-in-the-playground/14/) — When money stops working, for example after a war, people go back to barter, using things everyone wants like eggs or cigarettes.
- [15](https://md.mova.elamur.ai/free/en/corpora/school/money/4-swaps-and-barter-in-the-playground/15/) — "Got done" is British slang for being tricked in a deal.
