Words to know
growing crops and raising animals
a crop grown mainly to sell
changing farm products into other forms
having enough safe food to eat
1. Discover: From cocoa pod to chocolate
A farmer in the east grows cocoa. After harvest he opens pods, ferments and dries the beans and sells them to a trader. “The trader sends them to a factory far away,” he says. “There they become chocolate.” “You grow food, too?” asks Isatu. “Yes, rice and cassava for my family,” he says. “Cocoa brings money; rice brings food.”
Think: Why do farmers grow both food crops and cash crops?
2. Understand: Agriculture
Idea 1: Agriculture
Agriculture is growing crops and raising animals. It supplies food, raw materials and income. In Sierra Leone, most people depend directly or indirectly on agriculture.
Idea 2: Two kinds of crops
Food crops, like rice and cassava, feed the family. A cash crop, like cocoa, coffee or oil palm, is grown mainly to sell. Farmers often grow both. Processing changes farm products, such as turning cassava into gari or cocoa into chocolate.
Idea 3: Food security
Food security means everyone has enough safe, nutritious food. It depends on good harvests, storage, transport, fair prices and protecting soil and water. Wasting food harms food security.
3. Worked examples
Example 1 (I show you): Sort
Food or cash crop?
- Think.
- Sort.
- Say.
Answer: Rice food; cocoa cash.
Example 2 (We do it together): Process
One example.
- Think.
- Say.
- Check.
Answer: Cassava to gari.
Example 3 (You try): Secure
One way.
Show the steps and answer
- Think.
- Say.
- Check.
Answer: Good storage.
Did you know?
Sierra Leone exports cocoa and coffee, and cocoa from the east of the country is sold to chocolate makers around the world.
Why this matters
Food and income from agriculture support families and the nation.
4. Explore: Farm to market chart
Choose a crop. Draw its path from field to processing to market. Mark where value is added and where food could be wasted.
- Choose.
- Draw.
- Mark.
- Share.
Think about it: what did you notice?
What did you notice? Processing added value.
5. Practise

Courseversity badge thresholds (overall quiz score): Gold = 90–100%; Silver = 80–89.9%; Bronze = 70–79.9%. A badge is never a full record of progress.
If a learner struggles
- Find the misconception: “Cash crops cannot be eaten.” Some can; their main use is to sell.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a crop journey poster.
- 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 about agriculture. Please avoid wasting food together. You do not need to be an expert to help.
- Visit a farm.
- Save food.
- Support farmers.
- 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: explain agriculture; compare food and cash crops; describe processing; discuss food security.
Prerequisite knowledge. Grade 3 ideas: needs and wants, goods and services, and community livelihoods.
Materials. Paper, crayons. 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 crop pictures.
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 cocoa pod to chocolate story.
Explanation (10 min). Teach agriculture.
Guided activity (10 min). Farm to market chart.
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 does agriculture provide food and income?
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. “Cash crops cannot be eaten.” Some can; their main use is to sell.
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 crop journey poster. 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.
