Student lesson
- Transport networks link places by road, rail, water and air.
- Hubs and ports are key places.
- Modes differ in speed, cost and capacity.
- Safe travel needs rules and care.
Words to know
a system of linked routes
a central place where many routes meet
a place where roads or tracks meet or cross
a place where ships load and unload goods and people
1. Discover: Roads, boats and planes
Mr Cole draws four lines on the board: a road, a railway, a river and an air route. “Each is a way to move people and goods,” he says. “A lorry is flexible. A ship can carry huge loads cheaply. A plane is fast but costly.” Abu asks, “How do people get from Freetown to Lungi airport?” “By ferry or boat across the estuary, or by road around it,” says Mr Cole.
Think: Which type of transport would you choose to send fresh fish a long way? Why?
2. Understand: Transportation networks
Idea 1: Modes
A network links places. Roads suit short and medium trips and reach villages. Railways carry heavy loads on land. Ships and boats move large loads cheaply by water. Aircraft are fastest but cost the most. People choose the mode by speed, cost, capacity and distance.
Idea 2: Hubs, junctions and ports
A hub is a place where many routes meet, such as a big city or airport. A junction is where roads cross. A port loads and unloads ships; Freetown has the main seaport of Sierra Leone, and Lungi has the international airport. Ferries and boats link Freetown with Lungi across the estuary.
Idea 3: Effects and safety
Good roads help farmers reach markets and let health workers reach villages; towns grow at junctions and ports. Poor roads cut off places in the rainy season. Travel safely: use footpaths, cross roads with adults, wear seat belts and life jackets, and follow rules.
3. Worked examples
Example 1 (I show you): Name
Three modes.
- Think.
- List.
- Say.
Answer: Road, boat, plane.
Example 2 (We do it together): Define
Hub.
- Think.
- Say.
- Check.
Answer: Where routes meet.
Example 3 (You try): Compare
Plane and ship.
Show the steps and answer
- Think.
- Say.
- Check.
Answer: Plane faster, ship cheaper.
Did you know?
Sierra Leone had a railway from 1898 to 1974, and its route helped towns such as Bo and Kenema to grow.
Why this matters
Transport networks decide how easily people, food and goods can move.
4. Explore: Network map
Draw a map with six places. Join them with roads, a river route and an air route. Mark one hub and one port, and write which mode carries food, passengers and heavy goods.
- Draw.
- Join.
- Mark.
- Explain.
Think about it: what did you notice?
What did you notice? Hubs gather routes.

If a learner struggles
- Find the misconception: “All transport is the same.” Modes differ.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a transport 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 studies transport networks. Please practise road and water safety together. You do not need to be an expert to help.
- Practise road safety.
- Look at maps.
- Talk about travel.
- 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: name transport modes; explain hubs and ports; compare modes; explain safety.
Prerequisite knowledge. Unit 4 ideas: continents, landforms, climate regions and where people live.
Materials. Maps, paper, pencils. 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 transport 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 roads, boats and planes story.
Explanation (10 min). Teach transport networks.
Guided activity (10 min). Network 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. How do transport networks link places and shape settlement?
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. “All transport is the same.” Modes differ.
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 transport 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.
