Words to know
how much of a product buyers want and can pay for at a given price
how much of a product sellers offer at a given price
when demand is greater than supply
when supply is greater than demand
1. Discover: Mangoes at the market
Ms Smith runs a pretend market. At first, ten sellers each have five mangoes and few buyers come. Mangoes pile up, so sellers lower the price to 3 tokens. Later, a festival brings many buyers while mangoes are few, so prices rise to 7 tokens. “Demand and supply moved prices,” she says. “A fair market also needs honest scales and clear prices so buyers and sellers can trust each other.”
Think: What might sellers do if they have many unsold mangoes?
2. Understand: Markets and prices
Idea 1: Markets
A market is any place or system where buyers and sellers meet to exchange goods and services. Markets can be village markets, shops, or online platforms. The amount of a product that buyers want and can pay for is demand; the amount sellers offer is supply.
Idea 2: How prices move
When demand is higher than supply there is a shortage, and prices tend to rise. When supply is higher than demand there is a surplus, and prices tend to fall. At the balance point, called equilibrium, the amount buyers want equals the amount sellers offer. Competition among sellers can keep prices fair.
Idea 3: Fair markets
Fair markets need honest weights, clear prices, truthful descriptions and consumer protection rules. Governments, market committees and consumer groups help protect buyers and sellers. People can compare prices and quality to make informed choices.
3. Worked examples
Example 1 (I show you): Define
Demand.
- Think.
- Say.
- Check.
Answer: How much buyers want.
Example 2 (We do it together): Define
Surplus.
- Think.
- Say.
- Check.
Answer: Supply greater than demand.
Example 3 (You try): Name
A way markets stay fair.
Show the steps and answer
- Think.
- Say.
- Check.
Answer: Honest scales.
Did you know?
Online markets let sellers reach buyers in other towns or countries, though prices still follow demand and supply.
Why this matters
Understanding markets helps us make informed choices as buyers and sellers.
4. Explore: Pretend market
Run a pretend mango market with tokens. In round one there are many sellers and few buyers; in round two many buyers and few sellers. Record prices each round and explain why they changed.
- Prepare.
- Trade.
- Record.
- Explain.
Think about it: what did you notice?
What did you notice? Prices follow demand and supply.

If a learner struggles
- Find the misconception: “Prices are set by one person only.” Demand and supply matter.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a price chart.
- Guided practice: work through one example together and let the learner try the next one.
- Reassess: use the quiz again or the worksheet.
- Move on when the learner shows Silver-level evidence independently.
For parents and guardians
In this lesson your child runs a pretend market with tokens. Please talk about fair prices. You do not need to be an expert to help.
- Discuss fair prices.
- Compare prices.
- Use pretend money.
- Ask “how do you know?” after each answer, and listen.
- Praise effort, not only right answers. Mistakes are how we learn.
- Ten to fifteen minutes a day is better than one long session.
Teacher package
1–5. Objectives, prerequisites, materials, preparation, duration
Lesson objectives. Learners will: define market, demand, supply, price, shortage, surplus; explain how prices change; describe local and online markets; discuss fairness in markets.
Prerequisite knowledge. Grade 5 ideas: needs and wants, goods and services, producers and consumers, why people trade, imports and exports.
Materials. Tokens, goods cards. Low-resource options: use chalk or charcoal on a board or wall, drawings in the sand, and objects from the classroom instead of printed materials.
Preparation. Prepare tokens and cards.
Suggested duration. 45–60 minutes. It can be split into two shorter sessions.
6–9. Teaching procedure, explanation notes, guided and independent activities
Introduction (5 min). Tell the mangoes at the market story.
Explanation (10 min). Teach markets and prices.
Guided activity (10 min). Pretend market.
Independent activity (10 min). Discuss.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. How do demand and supply set prices?
Teacher explanation notes. Start with a picture, story, map or local example. Then talk about what was seen, then draw and write. Always ask “how do you know?” and invite more than one view. Treat every family, culture and community with respect, and never ask learners to share private information.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use pictures, maps, real objects and short sentences, and let learners work with a partner. Let learners point, show, act or draw instead of writing. Extension. Ask learners to find a new example from their own community and explain how they know.
Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.
Misconceptions. “Prices are set by one person only.” Demand and supply matter.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz, the 10-mark exam practice and the worksheet on this page. All answers and marking guides are in the answer sections above. Re-check every answer before use.

Remediation. Make a price chart. Enrichment. Find one new example near your home or school, draw or write about it and explain it to someone. Homework. See above.
Teacher reflection. After teaching, record: which ideas learners understood; which misconceptions occurred; which activities worked; which learners need more practice; and what to improve next time.
