1. Discover: Salt for grain
Ms Smith tells of two villages. One lives near a salty lake and has plenty of salt. The other farms rich land and has extra grain. “We have too much salt and too little grain,” say the first. “We have too much grain and too little salt,” say the second. So they meet at a crossing place and swap. Soon travellers bring shells, cloth and stories too. “That is how trade begins,” says Ms Smith.
Think: What is fair when two groups swap goods?
2. Understand: Trade beginnings
Idea 1: Why trade began
When people had a surplus and needed things they could not make or find, they began to trade. At first this was barter: swapping goods for other goods. Gifts between families and leaders also built friendships and agreements.
Idea 2: What was traded
Goods included salt, grain, cloth, pottery, stone for tools, copper, shells and obsidian, a glassy volcanic rock that can be chipped to a very sharp edge. Obsidian travelled hundreds of kilometres in early times. In West Africa, salt, dried fish, cloth and kola nuts were traded for many centuries.
Idea 3: Routes and ideas
A trade route followed rivers, coasts, forest paths and desert tracks. Traders carried more than goods: they carried news, skills, crops and beliefs. Trade could link distant peoples, but it also needed trust and fair dealing.
3. Worked examples
Example 1 (I show you): Name
Two traded goods.
- Think.
- List.
- Say.
Answer: Salt, cloth.
Example 2 (We do it together): Explain
Why barter?
- Think.
- Say.
- Check.
Answer: Need what others have.
Example 3 (You try): Route
One route type.
Show the steps and answer
- Think.
- Say.
- Check.
Answer: River.
Did you know?
Obsidian, a glassy rock formed by volcanoes, was traded over long distances in early times because it can be chipped to a very sharp edge.
Why this matters
Trade connected distant peoples and spread ideas that changed societies.
4. Explore: Barter game
Use pretend goods on cards, such as grain, salt, cloth and shells. Barter with partners, record each swap, and decide whether each swap felt fair and why. Draw a map of the trade route.
- Prepare.
- Swap.
- Record.
- Reflect.
Think about it: what did you notice?
What did you notice? Both sides must want the swap.
5. Practise

If a learner struggles
- Find the misconception: “Early people never traded.” They traded widely.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a trade route map.
- 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 learns how trade began. Please talk about markets and where goods come from. You do not need to be an expert to help.
- Visit a market.
- Discuss fairness.
- Look at labels.
- 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 and barter; name early traded goods; describe trade routes; explain spread of ideas.
Prerequisite knowledge. Grade 4 ideas: how historians use evidence, chronology and timelines.
Materials. Cards, pictures, paper. 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 pretend 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 salt for grain story.
Explanation (10 min). Teach trade beginnings.
Guided activity (10 min). Barter game.
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 begin and what did it spread?
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. “Early people never traded.” They traded widely.
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 route map. 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.
