Start studying economics with a thousand won?
A very easy financial story between middle school student Yubin and her mother.
Learning the Economics of Allowance Through Key Concepts in Economics Textbooks

Is economics difficult? Easy? Few students would confidently answer "easy!"
The author of this book, expert lecturer Kim Young-ok, discovered that children have a "dual attitude" toward the economy while conducting special economics lectures at elementary, middle, and high schools across the country.
The rich dream, but they hate to study economics.
When 286 middle school students were surveyed about what they wanted to know about the economy, most of them were interested in things related to money, such as how to become rich, part-time jobs, and salary, and were passive when it came to knowing economic concepts and common sense.
Responses were things like, “I’m still a student, do I need to know about economics?” and “I’m not going to major in economics in college later.”

However, the author explains that economics is the most practical knowledge.
"Economics for Teenagers: Starting with a Thousand Won" focuses on the "small allowances" that children encounter in everyday life, for the sake of children who find economics difficult and avoid it.
It combines interesting stories and economic concepts for each amount, such as 1,000 won, 5,000 won, 10,000 won, and 50,000 won.
As the amount of money increases, the scope of concepts covered also expands, so you can naturally draw the big picture of economics.

Actually, we started studying economics in elementary school.
In particular, we learn about scarcity and opportunity cost in the unit 'Production and Exchange of Necessary Things' in the second semester of the fourth grade social studies course.
In fact, if you go to class at an elementary school, everyone has bright eyes and answers well.
Even up to the 6th grade, I easily remember the concepts I learned.
But, strangely enough, when you go to middle school and ask students about scarcity and opportunity cost, not many of them can answer.
I learned it in the 4th grade of elementary school, but when I ask if they remember, only one or two people raise their hands like beans in a drought.
It seems that many students think that economic common sense is not necessary right now.
In fact, it is knowledge that is absolutely necessary in life.

What concepts were students interested in? According to the survey, they expressed interest in interest, how to become rich, stocks, credit and check cards, part-time jobs, and Bitcoin.
The first thing I wanted to know was how to make a lot of money.
But there was less interest in other economic terms.
I thought words like supply and demand, inflation, compound interest, and simple interest only appeared on tests and were difficult to understand.
I'm curious about things related to money, but I don't want to study economics.

Economics may seem daunting, but it actually allows us to think about many things that happen in our daily lives through economics.
The same thing happened when Yubin bought banana milk at a convenience store.
In economics, the desire to buy something, like Yubin's, is called demand.
A person who wants to buy something is called a demander.
If the desire to buy banana milk is a demand, then Yubin, who wants to buy banana milk, can be called a demander.
--- p.18~19

Now that we've covered demand, let's look at its counterpart, supply. If we understand demand from the perspective of consumers who buy goods, we should understand supply from the perspective of sellers who produce and sell goods.
The banana milk company needs to make money by selling banana milk.
Trying to sell something like this is called supply.
A company that makes and sells banana milk is called a supplier.
A banana milk company would want to sell its milk at a fair price, right? They also consider the costs of producing the milk and the profit they hope to make.
Companies that manufacture goods have specific prices and quantities for how much profit they can make if they sell this much at this price.
In other words, supply is the specific quantity that suppliers are willing to sell at a particular price.

"mom.
“I would like to receive an allowance once a month starting this week.”
Mom asked back, wondering what was going on with the sudden suggestion.
“Why did you suddenly think of that?”
Yubin couldn't bring herself to tell the real reason.
“That’s true.
You know the saying, "Three times three times three times," right? We learned about interest in school today, and in economics, they say that "Three times three times three times three times" is more rational than "Three times three times three times three times."
I also think that if I’m going to receive the money anyway, it’s more economical to receive it in advance.”
“Our Yubin thought about all those things.
But what if I spend all my monthly allowance in one go? Then I'll have a hard time getting by for the rest of the year...
“Think again about which is more economical.”
'Oh my! That could be possible.'
Yubin's head became complicated again after hearing her mother's words.
“Which is more economical?”
After much thought, I came to a conclusion.
Rather than deciding whether to receive your allowance once a week or once a month, it's more economical to think about how to receive more.
