D2.Eco.3.6-8: Buyers and Sellers in Product, Labor and Financial Markets
In plain English: D2.Eco.3.6-8 is the C3 Framework economics indicator for grades 6-8 that asks students to explain the roles of buyers and sellers in product, labor and financial markets. Students learn that households buy goods and sell their work, businesses sell goods and hire workers, and savers and borrowers trade the use of money for interest.
Explain the roles of buyers and sellers in product, labor, and financial markets.
C3 Framework for Social Studies (NCSS) · Dimension 2: Applying Disciplinary Concepts and Tools · Discipline: Economics · Exchange and Markets · Official standard
D2.Eco.3.6-8 asks students to explain the roles of buyers and sellers in three kinds of markets. A market is any place or system where buyers and sellers trade, from a store counter to a job website. In the product market, people buy goods and services from businesses. In the labor market, workers sell their work and employers buy it for a wage. In the financial market, savers let others use their money, and borrowers pay interest for that use. The big idea is that the same person or business plays different roles in different markets: a bakery sells bread, but it buys flour, hires workers and borrows money.
Students read part of Benjamin Franklin's 1748 letter of advice to a young tradesman about time, credit and borrowing (Source 1), work with real 2026 data from the U.S. Bureau of Labor Statistics on young people in the summer job market (Source 2), and analyze an invented scenario about one Saturday in a small town (Source 3). The activities ask students to sort roles, run a small market day and map the markets in a business they know.
Learning Objectives
By the end of this lesson, students will be able to:
Define a market, a buyer and a seller, and name what is traded in product, labor and financial markets
Explain what buyers and sellers each do in the product market
Explain why workers are the sellers and employers the buyers in the labor market
Explain the roles of savers, borrowers and banks in the financial market, and what interest is
Show that one person or business can be a buyer in one market and a seller in another, using evidence from sources
Prior Knowledge Required
Students should already be comfortable with:
Explaining how economic decisions affect individuals, businesses and society D2.Eco.1.6-8
Reading information from a table and connecting it to a text RH.6-8.7
Finding a percent of a quantity and multiplying with decimals 6.RP.A.3
"Think of three trades from the past month: something your family bought, a job someone you know was paid to do, and a time someone saved or borrowed money. In each trade, who gave something up, and what did they get back?"
Take a few answers and sort them on the board into three columns, without labels at first. Then label the columns Product market, Labor market and Financial market. Tell students that every trade has two sides, a buyer and a seller, and that D2.Eco.3.6-8 asks them to explain what each side does in each kind of market. Ask: "In the job example, who was the seller?" Many students say the business; the answer is the worker, who sells his or her time and skill.

Part 1: Three markets. Show Diagram 1. In each market, ask the same three questions: What is traded? Who is the buyer? Who is the seller? Buyers decide what they want and what it is worth to them, compare offers, and pay. Sellers decide what to offer, at what price, and try to win buyers. The price has a different name in each market: a price for goods and services, a wage for labor, and interest for the use of money.
Part 2: Switching roles. Stress that roles depend on the market, not on the person. A family is a buyer in the product market and a seller in the labor market. A business is a seller of goods and a buyer of labor. Banks and credit unions are go-betweens: they take in savers' money and lend it to borrowers. Work these examples.
Product market (invented)
Invented example: a school supply store sells graphing calculators for $15 each. In the first week of school, 40 students buy one. Who is the buyer, who is the seller, and what does each one do? How much does the store take in?
Result: 40 x $15 = $600. The store is the seller: it chose to stock calculators, set the $15 price and put them where students would see them. Each student (or family) is a buyer: each decided the calculator was worth $15 and may have compared it with prices elsewhere.
Labor market (invented)
Invented example: a summer day camp hires 6 counselors at $14 an hour for 25 hours a week, for 8 weeks. Who is the buyer and who is the seller of labor? What does each counselor earn, and what does the camp pay in wages?
Result: Each counselor: $14 x 25 x 8 = $2,800. The camp: 6 x $2,800 = $16,800. The counselors are the sellers: they offer their time and skills. The camp is the buyer: it decides how many workers it needs, what to pay and whom to hire. The wage is the price of their labor.
Financial market (invented)
Invented example: Leo puts $500 in a savings account that pays 3% interest a year. The bank lends $500 to a farmer at 8% a year. After one year, how much interest does Leo receive, how much does the farmer pay, and what is left for the bank?
Result: Leo receives 3% of $500 = $15. The farmer pays 8% of $500 = $40. The bank keeps $40 - $15 = $25 to cover its costs, such as wages and loans that are not repaid. Leo, the saver, supplies the use of money; the farmer, the borrower, pays interest for it; the bank connects them.
One person, three markets (invented)
Invented example: Rosa works 30 hours a week at a hair salon for $18 an hour. Each week she spends $120 on groceries and pays $45 in interest on a car loan. Name her role in each market and find her weekly pay.
Result: Weekly pay: 30 x $18 = $540. Labor market: Rosa is a seller of labor and the salon is the buyer. Product market: at the grocery store Rosa is a buyer. Financial market: Rosa is a borrower; the lender is paid $45 a week in interest for the use of its money. One person, three markets, two different roles.
Teacher tip. The labor market is where students most often mix up the roles, because the business hands over the money. Ask, "What is being sold?" The worker's time and skill are being sold, so the worker is the seller. In the financial market, the same question works: the saver gives up the use of money for a time, and the borrower pays interest for it.
Guided Practice15 minutes
Advice from 1748. Context note: Benjamin Franklin was a printer in Philadelphia before he became a scientist and a founder of the United States. In 1748 he wrote this letter of advice to a young tradesman, signed "An Old Tradesman." Money was counted in the British way: 12 pence made 1 shilling, and 20 shillings made 1 pound. The letter gives Franklin's own opinions, from the point of view of a business owner who sometimes borrowed money. Read Source 1 aloud. Glossary: "tradesman" (someone who runs a small business or skilled trade, like a printer or carpenter), "abroad" (out and about), "diversion" (fun or entertainment), "credit" (being trusted to pay later, a kind of loan), "interest" (money paid for using someone else's money), "paymaster" (a person who pays what he owes), "punctually" (on time), "creditor" (the person who is owed money), "tavern" (a place that serves drinks and meals), "in a lump" (all at once).
1Remember, that time is money. He, that can earn ten shillings a day by his labour, and goes abroad, or sits idle one half of that day, though he spends but sixpence during his diversion or idleness, ought not to reckon that the only expence; he has really spent, or rather thrown away, five shillings besides.
2Remember, that credit is money. If a man lets his money lie in my hands after it is due, he gives me the interest, or so much as I can make of it, during that time. This amounts to a considerable sum where a man has good and large credit, and makes good use of it.
[...]
3Remember this saying, "the good paymaster is lord of another man's purse." He that is known to pay punctually and exactly to the time he promises may at any time, and on any occasion, raise all the money his friends can spare. This is sometimes of great use. After industry and frugality, nothing contributes more to the raising of a young man in the world than punctuality and justice in all his dealings: therefore, never keep borrowed money an hour beyond the time you promised, lest a disappointment shut up your friend's purse for ever.
4The most trifling actions that affect a man's credit are to be regarded. The sound of your hammer at five in the morning, or nine at night, heard by a creditor, makes him easy six months longer: but if he sees you at a billiard-table, or hears your voice at a tavern, when you should be at work, he sends for his money the next day; demands it before he can receive it in a lump.
5It shows, besides, that you are mindful of what you owe; it makes you appear a careful as well as an honest man, and that still increases your credit.
Benjamin Franklin, Advice to a Young Tradesman, Written by an Old One (Source 1: time, credit and borrowing, 1748) (1748; this edition 1806). Public domain (published 1806). Source text.
Selling labor. Prompt: in paragraph 1, what is the young man selling, and what does it cost him to sit idle for half a day? Teacher note: he sells his labor, the work that "can earn ten shillings a day." Half a day idle costs the five shillings he did not earn plus the sixpence he spent: 5 x 12 + 6 = 66 pence. This is the seller's side of the labor market: his time has a price.
Credit as a loan. Prompt: in paragraph 2, a man "lets his money lie in my hands after it is due." Who is the lender and who is the borrower? Teacher note: the person owed money is the lender; the one who pays late (the writer) is the borrower. Letting a debt wait is a loan, so the lender "gives me the interest," the value of using the money in the meantime.
What lenders look for. Prompt: in paragraphs 3 and 4, how does a lender decide whom to trust? Teacher note: lenders watch whether a borrower pays "punctually and exactly" and works hard. The sound of the hammer at five in the morning makes a creditor "easy six months longer"; seeing the borrower at a billiard-table makes him ask for the money the next day. Lenders choose borrowers they expect to repay.
Label the roles. Pairs list every buyer, seller, lender and borrower they find in Source 1, with the market each one is in. Keep the lists for Activity 1.

Real data: young people in the labor market. Source 2 is real government data, not invented. It comes from the U.S. Bureau of Labor Statistics (BLS) news release Employment and Unemployment Among Youth, Summer 2026 (August 20, 2026; bls.gov, a US government work). "Youth" means people ages 16 to 24. The labor force is everyone who is working or actively looking for work, so it counts all the sellers of labor. The unemployment rate is the percentage of the labor force that has no job and is looking for one. BLS explains the summer jump this way: "During these months, large numbers of high school and college students search for or take summer jobs, and many graduates enter the labor market to look for or begin permanent employment."

Closure10 minutes
One town, three markets. Introduce Source 3, an invented scenario about one Saturday in a small town, for the quiz and the homework. Students read it once on their own.
1Invented scenario, written for this page. Cedar Bend is a fictional town of about 12,000 people. Here is what three of its people and businesses did one Saturday.
2Ana's Bakery. At 5 a.m., Ana and her two weekend helpers start baking. Ana pays each helper $13 an hour for 8 hours on Saturday. By closing time the bakery has sold 180 loaves of bread at $5 a loaf. On Monday Ana will pay the Riverside Mill for 20 bags of flour at $23 a bag. Last month Ana borrowed $8,000 from the Cedar Bend Credit Union to buy a bigger oven. She agreed to pay 6% interest a year on the loan.
3Jamal's day. Jamal is 16. He works as a lifeguard at the town pool for $12.50 an hour, 12 hours a week. On Saturday he stops at the credit union and puts $300 of his summer pay into a savings account that pays 2% interest a year. Then he buys a used bike at Pedal Shop for $180, after comparing prices at two other shops.
4The credit union. Cedar Bend Credit Union is owned by its members, the people who save there. It pays savers like Jamal 2% a year and charges borrowers like Ana 6% a year. The difference helps pay the tellers' wages, the rent and the cost of loans that are never paid back. On Saturday morning, the credit union's manager posts a sign: "Now hiring: part-time teller, $16 an hour."

Exit ticket: Choose one person or business from Source 3. Name one market where it is a buyer and one market where it is a seller (or a saver or borrower), and say what is traded in each.
Teacher note on the sources: Source 1 is quoted exactly as printed in the 1806 London edition of Franklin's works, with its old spellings, and gives one business owner's advice and opinions from 1748. Source 2 is real 2026 government data. Source 3 is invented. The lesson uses simple interest for one year only; how interest rates change borrowing is the subject of D2.Eco.10.6-8.
Differentiation Strategies
For Struggling Students
Give a three-row organizer (Product, Labor, Financial) with columns for What is traded, Buyer, Seller and Price name
Use the question "What is being sold?" as a sentence frame: "In this trade, ___ is being sold, so ___ is the seller and ___ is the buyer."
Read Source 1 one paragraph at a time and restate each in one plain sentence before answering
For Advanced Students
Explain why a credit union pays savers less interest than it charges borrowers, using the numbers in Source 3, and what would happen if it paid them the same rate
In Source 2, add the employed and the unemployed youth for July 2026 and compare the total with the July labor force. Explain why the two numbers are close but not exactly equal
Rewrite Franklin's paragraph 4 as advice for a teenager today who wants to borrow money for the first time
Assessment Guidance
What to Look For
Strong answers name the market, say what is traded, and identify the buyer and the seller correctly, especially in the labor market (workers sell, employers buy) and the financial market (savers supply money, borrowers pay interest). They show that one person or business can switch roles between markets, and they support each point with a quotation, a number from the data or a detail from the scenario. Watch for two confusions: calling the employer the seller because it hands over the money, and treating a bank as the only buyer or seller in the financial market instead of as a go-between.

Role Card Sort
15 minPairs
Pairs sort 12 trade cards into three piles, Product market, Labor market and Financial market. On each card they write B next to the buyer and S next to the seller (in the financial market, they mark the saver or lender and the borrower).
The 12 Trade Cards (invented)
A family pays $60 to fill the car's gas tank.
A hospital hires a nurse at $45 an hour.
A grandmother puts $1,000 into a savings account.
A pizza shop buys 50 pounds of cheese from a food supplier.
A college student takes out a $5,000 student loan.
A teenager works the weekend shift at a movie theater.
A city borrows money by selling bonds (IOUs that pay interest) to investors.
A farmer sells strawberries at a roadside stand.
A software company pays a programmer a yearly salary.
A family pays a plumbing company $150 to fix a leak.
A bakery gets a bank loan to buy a new oven.
A shopper buys a phone case online.
Sample Answers for the Teacher
Product market: cards 1, 4, 8, 10 and 12. On card 4 the buyer is a business, the pizza shop. Card 10 is a service, which is still sold in the product market; the plumbing company's own workers are in the labor market.
Labor market: cards 2, 6 and 9. The worker is the seller each time; the hospital, theater and software company are buyers.
Financial market: cards 3, 5, 7 and 11. The grandmother and the investors are savers or lenders; the student, the city and the bakery are borrowers.
Discussion Questions
On which cards was a business the buyer? What was it buying?
Card 10 is a family paying for a plumber's work. Why is it in the product market and not the labor market?
Modification for English Learners
Add a small picture to each card, and post the words buyer, seller, saver, borrower, wage and interest with a one-line definition in English and the student's home language.

Market Day Simulation
20 minWhole class, in three rounds
The class becomes a small economy. About two-thirds of students are households, about one-quarter run two or three businesses (for example, a bookmark shop and a paper-crane shop), and two students run the bank. Each round opens one market.
Rounds
Labor market (5 min): each household has 2 work tickets. Businesses need work tickets to make products and offer play-money wages. Households sell their tickets to whichever business offers the best deal.
Product market (5 min): businesses make one product for each work ticket they bought (a bookmark or a paper crane) and set prices. Households spend their wages on the products they want.
Financial market (5 min): households may deposit leftover money at the bank, which promises 1 play dollar of interest for every 10 saved. A business that wants to grow may borrow from the bank, which charges 2 play dollars for every 10 lent.
Debrief (5 min)
In which round were households sellers? In which were they buyers?
Why could the bank promise savers interest? Where did that money come from?
What did businesses do to attract workers in round 1 and buyers in round 2?
Modification for a Shorter Class
Run only rounds 1 and 2, and describe round 3 with the board example from Direct Instruction.

Directions: Part 1 is about roles in markets; use invented people, not private family details. Part 2 uses Sources 1-3 in the lesson plan. Answer in complete sentences and show any arithmetic.
Part 1: Roles in Markets (Problems 1-3)
For each trade, name the market and identify the buyer and the seller (or the saver or lender and the borrower): (a) a school district buys 30 laptops from a computer company; (b) a 17-year-old is hired as a grocery bagger; (c) a family borrows money from a bank to buy a house.
In three or four sentences, explain how the same person can be a seller in one market and a buyer in another. Use an invented person as your example and name both markets.
Invented example: Maya, 15, works 10 hours a week for 6 weeks at a farm stand for $12 an hour. She puts half of her total pay into a savings account that pays 4% interest a year. (a) What is her total pay? (b) How much does she save? (c) How much interest does she earn in one year? (d) Name her role in the labor market and in the financial market.
Part 2: Using the Sources (Problems 4-6)
Use Source 2. About how many employed young people worked in education and health services in July 2026? Show your work. Then name two kinds of employers that were the buyers of their labor.
Use Source 3. The credit union charges Ana 6% a year on her $8,000 loan. (a) How much interest does Ana pay in one year? (b) If the credit union pays savers 2% a year on the $8,000 that funded the loan, how much does it pay them? (c) How much is left over, and what does the credit union use it for?

0 of 20 answered · 0 correct
Question 1 of 20 · Multiple Choice
In Source 1, paragraph 1, what does the young man sell when he "can earn ten shillings a day"?
Answer: B
He earns the ten shillings "by his labour," so he is a seller in the labor market: he sells his time and skill. Choice A describes a merchant in the product market, which the paragraph does not mention. Choices C and D describe the financial market, the subject of paragraph 2, not paragraph 1.
Question 2 of 20 · Multiple Choice
Use the reasoning in paragraph 1. Invented example: a worker who can earn 8 shillings a day takes a whole day off and spends 9 pence at a fair. Counting both costs, how much does the day really cost him? (12 pence = 1 shilling.)
Answer: C
Franklin counts the lost earnings as well as the money spent: 8 x 12 = 96 pence not earned, plus 9 pence spent, is 105 pence. Choice A counts only the spending, the mistake Franklin warns against ("ought not to reckon that the only expence"). Choice B counts only the lost earnings. Choice D treats it as half a day off: 4 x 12 + 9 = 57.
Question 3 of 20 · Multiple Choice
In paragraph 2, a man "lets his money lie in my hands after it is due." What role does that man play?
Answer: A
The money is owed to him, and he lets the writer keep it past the due date, so he is lending it; Franklin says "he gives me the interest," the value of that use. Choice B reverses the roles: the writer is the borrower. Choices C and D describe the labor and product markets, but no work or goods change hands here.
Question 4 of 20 · Multiple Choice
What does Franklin mean in paragraph 3 by "The good paymaster is lord of another man's purse"?
Answer: D
The next sentence explains it: a man "known to pay punctually and exactly" can "raise all the money his friends can spare." Repaying on time earns a borrower trust in the financial market. Choice B reads "lord" too literally. Choices A and C are not in the paragraph.
Question 5 of 20 · Multiple Choice
In paragraph 4, why does "the sound of your hammer at five in the morning" make a creditor "easy six months longer"?
Answer: B
A lender wants to be repaid, so he watches how the borrower behaves. Hard work suggests the borrower will earn the money to pay; seeing him at a billiard-table makes the creditor ask for his money "the next day." Choice A invents a payment. Choice C misses that the creditor becomes more patient, not less. Choice D is not in the source.
Question 6 of 20 · Multiple Choice
Use Source 2. About how many employed young people worked in retail trade in July 2026?
Answer: A
Retail was 18% of the 21.3 million employed youth: 0.18 x 21.3 = 3.834, about 3.8 million. Choice B treats 18% as 18 million. Choice C takes 18% of the 23.5 million labor force, which includes people who have no job. Choice D is the number of unemployed youth.
Question 7 of 20 · Multiple Choice
Use Source 2. How did the youth unemployment rate change from July 2025 to July 2026?
Answer: C
It went from 10.8% to 9.1%: 10.8 - 9.1 = 1.7, a fall. A lower rate means a smaller share of young sellers of labor could not find a buyer. Choice A gets the direction wrong. Choice B gives the 2026 rate itself as the change. Choice D adds the two rates instead of subtracting.
Question 8 of 20 · Multiple Choice
In Source 2, how are the 2.1 million unemployed young people best described in labor-market terms?
Answer: D
To be counted as unemployed, a person must be in the labor force: available and looking for work. They are offering their labor but have not been hired. Choices A and B put workers on the buyers' side. Choice C describes people outside the labor force, whom the unemployment count leaves out.
Question 9 of 20 · Multiple Choice
According to the BLS sentence quoted in Independent Practice, why does the youth labor force grow from April to July?
Answer: B
BLS says that in these months "large numbers of high school and college students search for or take summer jobs, and many graduates enter the labor market." More sellers of labor enter the market. Choice A invents a law. Choices C and D describe the product and financial markets, which the sentence does not mention.
Question 10 of 20 · Multiple Choice
In Source 3, when Ana pays her two weekend helpers, she is a buyer in which market?
Answer: A
The helpers sell their work and Ana buys it for $13 an hour, so she is a buyer of labor. Choice B confuses this trade with selling bread, where Ana is a seller. Choice C is the market for her oven loan. Choice D is wrong because an owner who hires workers is still a buyer in the labor market.
Question 11 of 20 · Multiple Choice
Use Source 3. How much does Ana pay her two helpers in all for Saturday?
Answer: D
Each helper earns $13 x 8 = $104, and there are two: 2 x $104 = $208. Choice A is one helper's pay. Choice B is two helpers for one hour (2 x $13). Choice C doubles the hours, as if each helper worked 16 hours (2 x $13 x 16).
Question 12 of 20 · Multiple Choice
Use Source 3. How much interest will Jamal's $300 earn in one year?
Answer: C
2% of $300 is 0.02 x 300 = $6. Jamal is a saver: he lets the credit union use his money, and interest is the price it pays him. Choice A uses 20% instead of 2%. Choice B uses 0.2%. Choice D is his weekly lifeguard pay (12 x $12.50), not interest.
Question 13 of 20 · Multiple Choice
Which pair correctly names two of Jamal's roles in Source 3?
Answer: A
Jamal works as a lifeguard, so he sells his labor and the pool buys it; at Pedal Shop he pays $180, so he is a buyer in the product market. Choices B and D reverse his labor-market role. Choices C and D also make him a borrower, but he deposits $300, so he is a saver.
Question 14 of 20 · Multiple Choice
The credit union posts a sign: "Now hiring: part-time teller, $16 an hour." What does the sign show about the credit union?
Answer: D
By offering $16 an hour, the credit union is trying to buy someone's work, so it is a buyer in the labor market, even though in the financial market it is a go-between for savers and borrowers. Choice A reverses the roles. Choices B and C describe other markets; the sign is about hiring.
Question 15 of 20 · Short Answer
Using paragraphs 3 and 4 of Source 1, explain what a lender wants from a borrower. Name two kinds of behavior that make a lender trust a borrower.
Model answer: A lender wants to be repaid on time, with the interest it is owed. Franklin says a borrower who pays "punctually and exactly to the time he promises" can borrow again, and that a creditor who hears the borrower's hammer "at five in the morning" becomes patient, because hard work suggests the money will be earned. Seeing the borrower at a billiard-table or a tavern has the opposite effect. Rubric: 1 point for what the lender wants; 1 point for two behaviors supported from the source.
Question 16 of 20 · Short Answer
In Source 3, Ana's Bakery is both a seller and a buyer in the product market, and it also takes part in the financial market. Explain each of these three roles with one detail from the source.
Model answer: As a seller in the product market, the bakery sells loaves of bread to the town's shoppers. As a buyer in the product market, it buys 20 bags of flour from the Riverside Mill, another business. In the financial market it is a borrower: it borrowed $8,000 from the credit union, at 6% a year, to buy a bigger oven. Rubric: 1 point for each role with a correct detail (3 points).
Question 17 of 20 · Short Answer
Use Source 2. In July 2026, 25% of employed youth worked in leisure and hospitality, 18% in retail trade and 14% in education and health services. What percent worked in all other industries combined, and about how many young people is that? Show your work.
Model answer: 100% - 25% - 18% - 14% = 43%. 0.43 x 21.3 million = 9.159 million, about 9.2 million young workers in all other industries. Rubric: 1 point for 43%; 1 point for about 9.2 million (accept 9.1-9.2 million) using the 21.3 million employed.
Question 18 of 20 · Short Answer
Use Source 3. How much money did Ana's Bakery take in from bread on Saturday? What did Ana decide as the seller, and what did each customer decide as a buyer?
Model answer: 180 x $5 = $900. As the seller, Ana decided what to bake, how much, and the $5 price. Each customer decided whether a loaf was worth $5 to them and chose to buy it there. Rubric: 1 point for $900; 1 point for a seller decision and a buyer decision.
Question 19 of 20 · Short Answer
In Source 3, Jamal "buys a used bike at Pedal Shop for $180, after comparing prices at two other shops." What does this show about the role of a buyer, and how does it affect the shops as sellers?
Model answer: Buyers choose among sellers and pick the offer that gives them the most for their money. Because buyers like Jamal compare, each shop has a reason to keep its prices fair and its bikes in good shape, or it will lose the sale to another shop. Rubric: 1 point for the buyer's role; 1 point for the effect on sellers.
Question 20 of 20 · Short Answer
Compare Franklin's young tradesman in Source 1 with Ana in Source 3. What do both of them owe a lender, and how could Franklin's advice help Ana keep borrowing in the future?
Model answer: Both are borrowers who must repay what they borrowed plus interest on time; Ana owes the credit union 6% a year on $8,000. Franklin's advice, to pay "punctually and exactly" and to be seen working hard, would help Ana build trust, so the credit union would be willing to lend to her again when she wants to grow. Rubric: 1 point for what both owe; 1 point for applying a specific piece of Franklin's advice to Ana.

Frequently Asked Questions
10 Questions
What does D2.Eco.3.6-8 mean?
D2.Eco.3.6-8 asks middle school students to explain what buyers and sellers do in three kinds of markets. The full text is "Explain the roles of buyers and sellers in product, labor, and financial markets." It belongs to the Exchange and Markets part of the C3 Framework's economics standards for grades 6-8.
What is the difference between product, labor and financial markets?
They trade different things. Product markets trade goods and services, such as groceries or a haircut. Labor markets trade work, and the price is a wage. Financial markets trade the use of money for a period of time, and the price is interest. Many textbooks call product markets "goods and services markets."
Why is the worker the seller in the labor market?
Because the worker is the one offering something, his or her time and skill, and the employer pays for it. Students often guess the opposite because the business hands over the money. A quick test for any trade is to ask, "What is being sold, and who is giving it up?"
Who are the buyers and sellers in a financial market?
Savers and lenders supply money they do not need right now, and borrowers pay interest to use it. Banks and credit unions usually stand in the middle: they pay savers some interest and charge borrowers more, which covers their costs. Some books describe savers as "suppliers of funds" and borrowers as "demanders of funds"; the idea is the same.
Is D2.Eco.3.6-8 about supply and demand?
Not directly. D2.Eco.3.6-8 is about who the buyers and sellers are and what each one does. How changes in supply and demand move prices, wages and interest is the subject of D2.Eco.6.6-8, and the role of competition in setting prices and wages is D2.Eco.4.6-8. Knowing the roles first makes those lessons easier.
Why does this lesson use a letter from 1748?
Franklin's short letter talks about earning by labor, being trusted to pay later and repaying lenders, so it shows the labor and financial markets in plain words from a real business owner. It is also a primary source, so students practice reading an older text and noticing that it gives one person's opinions. The old money (shillings and pence) is explained in a context note.
Is the youth jobs data on this page real?
Yes. Source 2 comes from the Bureau of Labor Statistics release on youth employment for summer 2026, a US government work, and the page names the release and its tables. The figures are rounded, as BLS publishes them. The town scenario in Source 3 and every worked example marked invented are not real data.
How is D2.Eco.3.6-8 different from D2.Eco.3.9-12?
The grades 6-8 indicator asks students to explain the roles of buyers and sellers in three markets. The grades 9-12 indicator asks them to analyze how incentives influence what is produced and distributed in a market system. Knowing who buys and who sells prepares students to study why sellers decide to produce more of one thing and less of another.
Can students learn this without talking about their family's money?
Yes, and they should. Every activity on this page works with invented people and businesses, and the market map can be about any local business or an invented one. Teachers can model with their own invented examples so that no student has to share family income, savings or debts.
What is a good quick check for D2.Eco.3.6-8?
Give students a new trade, such as "a hotel hires a cook" or "a teen opens a savings account," and ask for the market, what is traded, the buyer and the seller. If students get the labor and financial cases right and can show one business in two different roles, they are meeting the indicator.
