a good that is bought and sold
to exchange goods without using money
money used in a country or region
1. Discover: Kola for salt
Mr Cole sets out cards: gold, salt, kola nuts, iron, cloth and rice. “Forest regions grew kola nuts, which were prized in the savanna,” he says. “Salt came from the coast and the desert. Traders carried goods along rivers and overland routes, exchanging by barter or with currencies such as cowrie shells and iron bars in some places.” Mei asks, “Did ideas travel too?” “Yes,” says Mr Cole, “news, languages, crafts and beliefs travelled with the traders.”
Think: Why is trade more than just buying and selling?
2. Understand: Regional trade
Idea 1: Goods and routes
A trade network is a system of connected routes and markets. West African commodities included gold, salt, kola nuts, iron, cloth, rice, palm oil and craft goods. Rivers such as the Rokel and Sewa, the coast and overland paths linked the forest and coast to the interior and to long-distance routes.
Idea 2: Barter and currency
Traders used barter to swap goods, and many also used currency. In parts of West Africa, cowrie shells, iron bars and, later, coins served as money. Markets set rules for weights, prices and fair dealing, and trusted traders and brokers helped.
Idea 3: Ideas on the move
Trade connected towns, cities and ports. Along with goods, traders carried news, languages, crafts, farming ideas and religions. Cities grew where routes met. Trade also had costs: not everyone gained equally, and some trade, such as the trade in people, caused terrible suffering, which later lessons study carefully.
3. Worked examples
Example 1 (I show you): Define
Barter.
- Think.
- Say.
- Check.
Answer: Exchange without money.
Example 2 (We do it together): Name
Two commodities.
- Think.
- Say.
- Check.
Answer: Kola and salt.
Example 3 (You try): Explain
Why markets grew where routes met.
Show the steps and answer
- Think.
- Say.
- Check.
Answer: Many travellers came.
Did you know?
Cowrie shells from the Indian Ocean were used as money in many parts of West Africa for hundreds of years.
Why this matters
Trade explains why towns grew and how distant peoples learned from each other.
4. Explore: Trade routes
On a map of West Africa, mark the forest, savanna and coast. Draw arrows showing where kola, salt and cloth could travel. Write which goods are exchanged and why each region needs the other.
- Mark.
- Draw.
- Explain.
- Share.
Think about it: what did you notice?
What did you notice? Regions needed each other.

If a learner struggles
- Find the misconception: “There was no trade in early Africa.” Trade was widespread.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a trade web.
- 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 studies trade networks. Please talk about where everyday goods come from. You do not need to be an expert to help.
- Read labels.
- Visit a market.
- Talk about trade.
- 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 trade network, commodity, barter, currency; name goods and routes; explain how trade connected places; explain spread of ideas.
Prerequisite knowledge. Grade 5 ideas: historical enquiry, sources, evidence and perspectives; Grade 4 early societies.
Materials. Maps, goods cards, tokens. 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 goods 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 kola for salt story.
Explanation (10 min). Teach trade networks.
Guided activity (10 min). Trade routes.
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 did trade link the regions of West Africa?
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. “There was no trade in early Africa.” Trade was widespread.
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.
16–19. Remediation, enrichment, homework, teacher reflection
Remediation. Make a trade web. 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.
