- Tributaries join larger rivers.
- Major rivers include the Nile, Amazon and Niger.
- Rivers give water, food, transport and power.
Words to know
the place where a river begins
a smaller river that flows into a larger one
the place where a river ends and flows into the sea or a lake
low land formed where a river splits and drops soil near its mouth
1. Discover: From spring to sea
Mr Cole traces a blue line on a map. “This little stream starts in the hills. It joins other streams. Together they make a river, which flows down to the sea.” Mei asks, “Which rivers are in Sierra Leone?” “The Rokel, also called the Seli, the Sewa, the Moa, the Mano and the Scarcies rivers,” says Mr Cole. “Some of them end in estuaries by the Atlantic Ocean.”
Think: Why do towns often grow along rivers?
2. Understand: Rivers
Idea 1: Parts of a river
A river begins at its source, often in hills or mountains. Tributaries join it along the way. It ends at its mouth, where it meets the sea or a lake. Near the mouth, many rivers drop soil to build a delta or widen into an estuary.
Idea 2: Famous rivers
The Nile in Africa (about 6,650 km) and the Amazon in South America (about 6,400 km) are among the longest, and experts debate which is longer. The Niger flows through West Africa for about 4,000 kilometres, starting in Guinea. The Congo, the Yangtze and the Mississippi are other great rivers. In Sierra Leone, the Rokel, Sewa, Moa, Mano and Scarcies rivers run towards the Atlantic.
Idea 3: Using and caring
Rivers give water for drinking and crops, fish, routes for boats, fertile land and power; the Bumbuna Dam on the Seli (Rokel) River produces hydroelectric power. Rivers can flood and can be polluted, so people must keep them clean and stay safe near the water’s edge.
3. Worked examples
Example 1 (I show you): Name
Two rivers.
- Think.
- List.
- Say.
Answer: Nile, Niger.
Example 2 (We do it together): Define
Tributary.
- Think.
- Say.
- Check.
Answer: Smaller river joining.
Example 3 (You try): Explain
One use.
Show the steps and answer
- Think.
- Say.
- Check.
Answer: Water for crops.
Did you know?
The Bumbuna Hydroelectric Project, finished in 2009 on the Seli (Rokel) River, was built to provide electricity for Sierra Leone.
Why this matters
Rivers support farming, towns and trade, and need protecting.
4. Explore: River journey
Draw a river from source to mouth. Add two tributaries, a village, a farm and a bridge. Label each part and one use.
- Draw.
- Add.
- Label.
- Present.
Think about it: what did you notice?
What did you notice? The river joins many places.

If a learner struggles
- Find the misconception: “Rivers flow uphill.” They flow downhill.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a river 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 rivers. Please talk about water safety. You do not need to be an expert to help.
- Look at maps.
- Discuss safety.
- Keep water clean.
- 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 river terms; name major rivers; describe uses; explain safety and care.
Prerequisite knowledge. Grade 3 ideas: reading maps, directions, keys, scale and physical and political maps.
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 river 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 spring to sea story.
Explanation (10 min). Teach rivers.
Guided activity (10 min). River journey.
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 rivers flow and why do people depend on them?
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. “Rivers flow uphill.” They flow downhill.
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 river 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.
