Student lesson
- Population is the number of people.
- A census counts people.
- Some areas are crowded; some are sparse.
- People settle where land, water and work are.
Words to know
the number of people living in a place
an official count of the people in a country
how crowded a place is
moving from one place to another to live
1. Discover: Counting people
Every few years, officials carry out a census. Abu’s teacher explains, “They visit homes and count people so the government can plan schools and clinics.” Ms Smith shows a map with dots. In Freetown the dots are crowded. In the north-east they are fewer. “Density shows how crowded a place is,” she says. “People gather where there are jobs, schools and roads.”
Think: Why might more people live in a city than in a village?
2. Understand: Population
Idea 1: Population
Population is the number of people living in a place. A census is an official count of people. Sierra Leone has several million people. Census information helps plan schools, clinics, roads and food.
Idea 2: Density
Density tells how crowded a place is. A densely populated place has many people in a small area; a sparsely populated place has few. The Western Area, including Freetown, is densely populated, while some northern and eastern areas have fewer people per square kilometre.
Idea 3: Why people live there
People settle where they can find jobs, water, farmland, roads, schools and clinics. Migration is moving to live in a new place, such as from a village to a town. Moves can bring opportunities, but also crowding and pressure on services.
3. Worked examples
Example 1 (I show you): Define
Census.
- Think.
- Say.
- Check.
Answer: An official count.
Example 2 (We do it together): Compare
Dense or sparse?
- Look.
- Compare.
- Say.
Answer: City dense; forest sparse.
Example 3 (You try): Explain
Why migrate?
Show the steps and answer
- Think.
- List.
- Say.
Answer: For jobs and school.
Did you know?
The first modern census in Sierra Leone was carried out in 1963, soon after independence, and censuses are used to plan services for the whole country.
Why this matters
Knowing about population helps governments and communities plan fairly.
4. Explore: Dot map
Make a dot map: one dot for 100,000 people (teacher data) on an outline map. Compare dense and sparse areas and give reasons.
- Plot.
- Compare.
- Reason.
- Share.
Think about it: what did you notice?
What did you notice? People gathered near the coast.
5. Practise

If a learner struggles
- Find the misconception: “Population is the same everywhere.” It varies.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a population 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 population and settlement. Please talk in general terms about why people move. You do not need to be an expert to help.
- Talk about moving.
- Look at maps.
- Avoid stereotypes.
- 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 population; explain a census; compare dense and sparse; explain settlement patterns.
Prerequisite knowledge. Grade 3 ideas: location, boundaries, regions, capital and landforms.
Materials. Outline map, stickers. 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 population data.
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 counting people story.
Explanation (10 min). Teach population.
Guided activity (10 min). Dot map.
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. Why do people live where they do?
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. “Population is the same everywhere.” It varies.
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 population 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.
