Student lesson
- Exports earn foreign exchange.
- Sierra Leone exports minerals and farm products.
- Processing adds value and jobs.
- Depending on few exports is risky.
Words to know
a good or service sold to another country
a natural material used to make other things, such as ore or cocoa beans
the extra value gained when a raw material is processed into a product
money from other countries that a country earns, used to pay for imports
1. Discover: From bean to bar
Mr Cole holds up a cocoa bean and a chocolate bar. “Most cocoa from Sierra Leone is exported as beans, a raw material,” he says. “When the beans are turned into chocolate, the price rises, because value is added. Iron ore and bauxite are other raw materials. The money earned from exports, called foreign exchange, pays for imports.” Abu asks, “What if the world price falls?” “Then the country earns less,” says Mr Cole. “That is why many countries try to export more kinds of goods.”
Think: What could Sierra Leone make from its raw materials?
2. Understand: Exports
Idea 1: What exports are
An export is a good or service sold to another country. Sierra Leone’s main exports include minerals such as iron ore, rutile, bauxite and diamonds, and farm products such as cocoa and coffee, as well as fish and timber. Exports earn foreign exchange, which pays for imports like fuel and machinery.
Idea 2: Raw materials and value
A raw material is a natural material used to make something else. Exporting raw materials earns less than exporting finished goods because the processing happens elsewhere. Value added is the extra value created by processing, such as turning cocoa beans into chocolate, fish into canned or smoked products or timber into furniture.
Idea 3: Diversifying
Relying on a few exports is risky: if world prices fall, earnings fall. Diversification means producing more kinds of goods and services, such as processed food, crafts and tourism. Good roads, power, training and fair rules help local businesses to add value and export more.
3. Worked examples
Example 1 (I show you): Define
Export.
- Think.
- Say.
- Check.
Answer: A good sold to another country.
Example 2 (We do it together): Name
Two exports.
- Think.
- Say.
- Check.
Answer: Cocoa and iron ore.
Example 3 (You try): Explain
Value added.
Show the steps and answer
- Think.
- Say.
- Check.
Answer: Extra value from processing.
Did you know?
Chocolate is made from the seeds of the cacao tree, which grows only in warm, wet regions near the Equator.
Why this matters
Knowing about exports shows how a country earns money and how it can grow stronger.
4. Explore: Add value
Choose a raw material (cocoa, fish, cotton, timber). Draw a chain from raw material to finished product, listing jobs created. Estimate how price changes at each step with pretend numbers. Explain why processing locally helps.
- Choose.
- Draw.
- Estimate.
- Share.
Think about it: what did you notice?
What did you notice? Each step added value.

If a learner struggles
- Find the misconception: “Raw materials are worthless.” They are valuable but processing adds more.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make an exports 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 studies exports. Please talk about how raw materials become products. You do not need to be an expert to help.
- Look at labels.
- Talk about processing.
- Support local makers.
- 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 export, raw material, value added, foreign exchange; name main exports; explain adding value; explain diversification.
Prerequisite knowledge. Grade 5 ideas: scarcity, choice, producers, consumers, supply, demand and prices.
Materials. Pictures, charts. 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 chain 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 from bean to bar story.
Explanation (10 min). Teach exports.
Guided activity (10 min). Add value.
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. What does Sierra Leone export and how can it earn more?
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. “Raw materials are worthless.” They are valuable but processing adds more.
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 an exports 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.
