Student lesson
- Sierra Leone has about eight million people.
- People are not spread evenly.
- Jobs, services and land shape where people live.
- Towns and cities are growing.
Words to know
the number of people living in a place
the number of people living in each square kilometre
the way something is spread across an area
the growth of towns and cities as more people move to them
1. Discover: Dots on the map
Mr Cole shows a map with dots, each standing for a thousand people. The dots are thick around Freetown and along main roads, and thinner in some inland areas. “Sierra Leone has roughly eight million people,” he says. “The Western Area, including Freetown, is the most crowded. Bo, Kenema and Makeni are other big centres. Many people move to towns for schools, jobs and markets.” Abu asks, “Why do some places have few people?” “Steep land, poor roads, or fewer services,” says Mr Cole.
Think: What would make you choose a place to live?
2. Understand: Population
Idea 1: How many and where
Population is the number of people in a place. Sierra Leone has roughly eight million people. Population density is the number of people per square kilometre. The Western Area, which includes Freetown, is the most densely populated; large populations also live in Bo, Kenema, Makeni and along the main highways.
Idea 2: The pattern
The distribution of people is uneven. People settle where there is water, fertile land, trade, jobs, schools and clinics. Steep highlands, dense forest, poor roads or lack of services mean fewer people. Population density maps use colours or dots to show the pattern.
Idea 3: Urbanisation
Urbanisation means towns and cities grow as people move to them for work, education and services. It can bring opportunity but also pressure on housing, water, roads and waste services. Governments and communities plan for growth by building services and supporting rural areas too.
3. Worked examples
Example 1 (I show you): Define
Population density.
- Think.
- Say.
- Check.
Answer: People per square kilometre.
Example 2 (We do it together): Name
The most densely populated area.
- Think.
- Say.
- Check.
Answer: The Western Area.
Example 3 (You try): Explain
One reason people move to towns.
Show the steps and answer
- Think.
- Say.
- Check.
Answer: Jobs and services.
Did you know?
More than half of the world’s people now live in towns and cities.
Why this matters
Knowing where people live helps governments plan schools, clinics, roads and markets.
4. Explore: Density detective
Use a population density map or table provided by the teacher. Rank five areas from most to least dense, suggest two reasons for the pattern and one service planners should provide in the densest area.
- Read.
- Rank.
- Explain.
- Share.
Think about it: what did you notice?
What did you notice? People gather where services are.
5. Practise

- Population is ___.
- Population density is ___.
- Distribution is ___.
- Urbanisation is ___.

If a learner struggles
- Find the misconception: “People are spread evenly.” They are not.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a population 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 studies where people live. Please talk about services in towns and villages. You do not need to be an expert to help.
- Look at a map.
- Talk about services.
- Respect all places.
- 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, density, distribution, urbanisation; describe where people live; explain reasons; read a density map.
Prerequisite knowledge. Grade 5 ideas: maps, scale, regions and resources from earlier grades.
Materials. Density maps, dots. 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 density maps.
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 dots on the map story.
Explanation (10 min). Teach population distribution.
Guided activity (10 min). Density detective.
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. Where do people live in Sierra Leone and why?
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. “People are spread evenly.” They are not.
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 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.
