Student lesson

- The WHO was founded in 1948.
- Smallpox was eradicated through cooperation.
- Hygiene, vaccines and trusted information protect communities.
Words to know
a sudden increase in cases of a disease in a community or region
an epidemic that spreads across many countries and continents
protecting people from disease, usually through vaccines
careful watching and reporting of disease to respond quickly
1. Discover: The disease that disappeared
Ms Smith tells the story of smallpox. For thousands of years it was a serious disease. In 1967 the World Health Organization launched an intensified programme, with countries sharing information, training health workers and vaccinating people. The last natural case was in 1977, and in 1980 the world was declared free of smallpox. “That took cooperation across the whole world,” she says. “In 2020 Africa was certified free of wild polio. Today health workers still watch for new outbreaks and share information.”
Think: Why does sharing information quickly help stop a disease?
2. Understand: Global public-health cooperation
Idea 1: Diseases cross borders
People travel and trade, so diseases can cross borders. An epidemic is a sudden rise in cases in a region; a pandemic spreads across many countries. Surveillance means watching and reporting disease so that responses can be quick.
Idea 2: The WHO and success stories
The World Health Organization (WHO), a UN agency, was founded on 7 April 1948, now marked as World Health Day. Smallpox, a deadly disease, was declared eradicated in 1980 after worldwide vaccination and surveillance. The WHO African Region was certified free of wild polio in 2020. Immunisation through safe vaccines protects people.
Idea 3: Keeping communities safe
Everyday protection includes handwashing, clean water, safe food, vaccination, staying home when unwell and seeking trusted health advice. Health workers, schools, families and governments cooperate. Fair access to medicines and trusted, clear information matter for everyone.
3. Worked examples
Example 1 (I show you): Define
Epidemic.
- Think.
- Say.
- Check.
Answer: Sudden rise in cases.
Example 2 (We do it together): Define
Immunisation.
- Think.
- Say.
- Check.
Answer: Protection by vaccines.
Example 3 (You try): Name

Answer: Smallpox.
Did you know?
World Health Day is celebrated every year on 7 April, the anniversary of the WHO’s founding.
Why this matters
Health cooperation keeps communities safe and strong.
4. Explore: Health cooperation timeline
Using a given fact sheet, build a timeline of smallpox eradication (1967 programme, 1977 last natural case, 1980 declaration). Write three sentences about how cooperation helped and list three everyday habits that protect health.
- Read.
- Build.
- Write.
- List.
Think about it: what did you notice?
What did you notice? Many people had to work together.

If a learner struggles
- Find the misconception: “Diseases stop at borders.” They can cross borders.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a health cooperation 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 how countries cooperate on health in a calm way. Please practise handwashing together. You do not need to be an expert to help.
- Wash hands.
- Ask health workers for advice.
- Avoid scary talk.
- 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 epidemic, pandemic, vaccine, immunisation, surveillance; describe the WHO; explain cooperation using smallpox and polio; explain how communities stay safe.
Prerequisite knowledge. Grade 6 ideas: why countries cooperate, international organisations, the United Nations, the African Union and ECOWAS.
Materials. Fact sheet, timeline. 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 timelines.
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 disease that disappeared story.
Explanation (10 min). Teach health cooperation.
Guided activity (10 min). Health cooperation timeline.
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 countries cooperate on health?
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. “Diseases stop at borders.” They can cross borders.
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 health cooperation 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.
