1. Discover: The honest trader
Kadiatu sells groundnuts. She weighs them honestly, tells the price clearly and counts change carefully. A customer asks if she can lower the price. “Let us agree on a fair one,” Kadiatu says. Mr Cole says, “She earns trust. Buyers come back to honest sellers.” Isatu’s mother compares two stalls before buying.
Think: What makes a trader trustworthy?
2. Understand: Buyers and sellers
Idea 1: Roles
A buyer pays for goods or services. A seller offers goods or services for sale. Each depends on the other and each should treat the other fairly.
Idea 2: Wise buying
Wise buyers make a budget, compare prices and quality, check change and avoid wasting. They buy what they need first and save for wants.
Idea 3: Honest selling
Honest sellers show clear prices, use fair weights, describe goods truthfully and give correct change. Buyers have rights: to safe goods, honest information and fair treatment. Both should be polite.
3. Worked examples
Example 1 (I show you): Compare
Two stalls.
- Look.
- Compare.
- Say.
Answer: Better quality, similar price.
Example 2 (We do it together): Change
Pay 10, cost 7.
- Subtract.
- Say.
- Check.
Answer: 3 (pretend).
Example 3 (You try): Honest
One habit.
Show the steps and answer
- Think.
- Say.
- Check.
Answer: Fair weight.
Did you know?
Consumer protection laws in many countries give buyers the right to safe goods and honest information.
Why this matters
Fair trade builds trust and helps both buyers and sellers.
4. Explore: Buyers and sellers role play
Role-play a stall with pretend money. Sellers use clear prices and fair weights; buyers compare and check change. Swap roles and reflect.
- Set up.
- Trade.
- Swap.
- Reflect.
Think about it: what did you notice?
What did you notice? Honesty made trading easier.

If a learner struggles
- Find the misconception: “Sellers may cheat if buyers do not notice.” Cheating is wrong.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a shopper’s checklist.
- 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 practises wise buying and honest selling. Please practise with pretend money at home. You do not need to be an expert to help.
- Compare prices.
- Be honest.
- Budget together.
- 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

Lesson objectives. Learners will: describe buyer and seller roles; explain wise buying; explain honest selling; use pretend money.
Prerequisite knowledge. Grade 3 ideas: needs and wants, goods and services, and community livelihoods.
Materials. Pretend money, goods. 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 stalls.
Suggested duration. 45–60 minutes. It can be split into two shorter sessions.
6–9. Teaching procedure, explanation notes, guided and independent activities

Key questions. How do wise buyers and honest sellers behave?
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. “Sellers may cheat if buyers do not notice.” Cheating is wrong.
