My name is Jisu, and I am in the fourth grade. Last Friday, our school held a special market day in the gym. All the kids brought old toys and books to sell to their classmates. In Korea, our money is called won, so all the prices were in won.
Before the market opened, our teacher told us an interesting story. Long ago, there was no money, so people had to trade one thing for another. For example, a farmer might give rice to a fisher to get some fish. But what if the fisher did not want any rice? Because trading was often difficult, people started to use money instead.
At my table, I sold my old puzzle first. Its price was 500 won. A boy gave me a 1,000-won bill, so I gave him 500 won in change. I felt happy because it was my very first sale.
Later, I noticed a cute pencil case that cost 2,000 won. I really wanted it, but I did not need it, because I already had one at home. So I decided not to spend my money on it.
When I got home, I put my money into my piggy bank. Mom said, "If you save a little every week, you can buy something special later." Now I am saving for a new book about space. I learned that money is a useful tool when we stop and think before we use it.
