Student lesson
Words to know
the way people use an area of land, such as farming, housing or forest
growing food mainly for the farmer’s own family
growing crops or raising animals mainly to sell
growing trees together with crops or livestock
1. Discover: The terraced hill
Ms Smith shows a photograph of a made-up hill with rows of crops on terraces and trees between them. “Farmers in many places grow rice in swamps and on uplands, cassava, groundnuts, vegetables, cocoa and oil palm,” she says. “When forest is cleared quickly or hillsides are left bare, rain can wash away soil. Terraces, mulch, crop rotation and agroforestry keep soil healthy so harvests continue.”
Think: How can farmers produce food and still protect the land?
2. Understand: Agriculture and land use
Idea 1: How land is used
Land use describes how people use land: farms, forests, towns, roads, mines and protected areas. In Sierra Leone, many families practise subsistence farming for food, and some practise commercial farming of crops like cocoa, coffee and oil palm for sale. Rice is the staple crop, grown on uplands and in swamps.
Idea 2: Pressures on land
Growing populations and the need for income can place pressure on land. Clearing forests and leaving soil bare can cause soil erosion. Using the same plot continuously without rest can reduce fertility. Some farmers practise shifting cultivation, rotating plots to let land recover, but shorter rests cause problems.
Idea 3: Sustainable farming
Methods that protect soil and yields include crop rotation, mulching, compost, terracing on slopes, planting cover crops and agroforestry, which combines trees and crops. Training, fair prices and secure land rights help farmers invest in the land for the long term.
3. Worked examples
Example 1 (I show you): Define
Land use.
- Think.
- Say.
- Check.
Answer: How people use land.
Example 2 (We do it together): Define
Soil erosion.
- Think.
- Say.
- Check.
Answer: Soil being washed or blown away.
Example 3 (You try): Name
A sustainable farming method.
Show the steps and answer
- Think.
- Say.
- Check.
Answer: Crop rotation.
Did you know?
Healthy soil contains billions of living organisms in just a handful.
Why this matters
Protecting farmland keeps food available for everyone.
4. Explore: Plan a plot
On a drawn plot with a slope, plan crops, trees and a path for runoff. Show two sustainable methods and explain how they protect soil.
- Draw.
- Plan.
- Add.
- Explain.
Think about it: what did you notice?
What did you notice? Good planning protects soil.

If a learner struggles
- Find the misconception: “Soil lasts forever without care.” It can erode or lose fertility.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a land use 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 farming and land. Please talk about the food on your table and where it grows. You do not need to be an expert to help.
- Grow a plant.
- Compost scraps.
- Respect 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: define land use, subsistence and commercial farming, erosion, agroforestry; describe farming in Sierra Leone; explain pressures on land; explain sustainable practices.
Prerequisite knowledge. Grade 5 ideas: natural resources, land use, resource management and conservation.
Materials. Plot sheets, markers. 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 plot sheets.
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 terraced hill story.
Explanation (10 min). Teach land use.
Guided activity (10 min). Plan a plot.
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 can farming feed people and protect the land?
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. “Soil lasts forever without care.” It can erode or lose fertility.
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 land use 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.
