BTrading one good or service directly for another without using money
CGiving something away for free
DStealing something from someone
Barter is trading goods or services directly without using money. For example, if you trade your apple for your friend's cookies, that is barter. People used this system for thousands of years before money was invented.
Question 2 True / False
Money was invented because bartering can be difficult.
TTrue
FFalse
Answer: True
Bartering has a big problem: both people have to want what the other person has. If you have fish and want bread, but the bread maker does not want fish, you are stuck. Money solved this problem because everyone accepts money — you can sell your fish for money and then use that money to buy bread.
Question 3 Short Answer
Explain why money makes trading easier than bartering.
Think about your answer, then reveal below.
Model answer: Money makes trading easier because everyone agrees on its value. With barter, you have to find someone who wants exactly what you have and has exactly what you want. With money, you can sell anything to anyone and use the money to buy what you need from someone else.
A good answer explains the main problem with barter (you need a 'double coincidence of wants') and how money solves it by being a universal medium of exchange that everyone accepts.
Question 4 Multiple Choice
Which of these is an example of trading?
AFinding a dollar on the ground
BSwapping your sandwich for your friend's crackers at lunch
CThrowing away something you do not want
DBorrowing a book from the library
Swapping your sandwich for your friend's crackers is trading — you are giving something you have in exchange for something you want. Finding money is luck, throwing things away is discarding, and borrowing is temporary — none of those are trades.
Question 5 True / False
Trade only happens inside stores.
TTrue
FFalse
Answer: False
Trade happens everywhere, not just in stores. When you swap snacks with a friend at lunch, that is trade. When a farmer sells vegetables at a roadside stand, that is trade. When your family buys something online, that is trade. Whenever someone gives something in exchange for something else, trade is happening.
