Student lesson
- Smallpox was eradicated by 1980.
- Cooperation, shared goals and local knowledge were essential.
- Methods included surveillance and ring vaccination.
- Success depended on trust and resources.
Words to know
the complete and permanent removal of a disease from the world
vaccinating people around a case to stop the spread
a set of approved documents, maps and data for research
facts or information that support a conclusion
1. Discover: Closing the case
Ms Smith opens a source pack with a map of countries, a timeline from 1967 to 1980, short facts about surveillance and ring vaccination, and a chart showing falling case numbers. “Your task is to understand how this succeeded,” she says. “Look for who worked together, what they did and what made trust and teamwork possible. Also notice what was hard: reaching remote places, rumours, and funding. Write a conclusion using evidence.” Pupils record facts and their own reasons in a two-column chart.
Think: What would be the first fact you would look for in the pack?
2. Understand: International cooperation case study
Idea 1: The problem and the plan
Smallpox was a serious disease with high risks. In 1967 the WHO began an intensified eradication programme. Countries shared data, trained health workers, supplied vaccine and organised surveillance to find cases quickly. Ring vaccination protected people around each case.
Idea 2: Why it worked
Factors included a clear shared goal, a vaccine that worked well, cooperation between countries and local communities, reliable reporting, training and funding. The last natural case was in 1977, and in 1980 the world was declared free of smallpox. Eradication is rare: only smallpox in humans, and a livestock disease called rinderpest in 2011, have been fully eradicated.
Idea 3: Writing the case study
Use the source pack to state the problem, order events, list who cooperated, explain methods, describe success factors and challenges and give a balanced conclusion using evidence. Name the sources so others can check.
3. Worked examples
Example 1 (I show you): Define
Eradication.
- Think.
- Say.
- Check.
Answer: Permanent removal of a disease.
Example 2 (We do it together): Define
Ring vaccination.
- Think.
- Say.
- Check.
Answer: Vaccinating around a case.
Example 3 (You try): State
The year smallpox was declared eradicated.
Show the steps and answer
- Think.
- Say.
- Check.
Answer: 1980.
Did you know?
Rinderpest, a disease of cattle, was declared eradicated in 2011, the second disease ever to be eradicated.
Why this matters
Case studies show how cooperation can solve real global problems.
4. Explore: Smallpox case file
Use the teacher’s source pack to build a timeline, fill a who-did-what table, list four success factors and two challenges, and write a 120-word balanced conclusion with sources. Compare with another pupil.
- Read.
- Build.
- List.
- Write.
Think about it: what did you notice?
What did you notice? Evidence and teamwork won.

Courseversity badge thresholds (overall quiz score): Gold = 90–100%; Silver = 80–89.9%; Bronze = 70–79.9%. A badge is never a full record of progress.
If a learner struggles
- Find the misconception: “One country eradicated smallpox alone.” Many cooperated.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a case study 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 the world worked together to end smallpox. Please talk about teamwork. You do not need to be an expert to help.
- Discuss teamwork.
- Ask about evidence.
- Stay hopeful.
- 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: trace a timeline from a source pack; identify who cooperated and how; identify success factors and challenges; write a balanced conclusion.
Prerequisite knowledge. Grade 6 ideas: why countries cooperate, international organisations, the United Nations, the African Union and ECOWAS.
Materials. Source packs, tables. 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 source packs.
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 closing the case story.
Explanation (10 min). Teach case study skills.
Guided activity (10 min). Smallpox case file.
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 did countries work together to end smallpox?
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. “One country eradicated smallpox alone.” Many cooperated.
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 case study 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.
