Words to know
looking at two or more things to see how they are alike and different
a close study of one example to understand something bigger
a broad statement based on a few examples
the points used to compare things fairly
1. Discover: Two trading cities
Ms Smith asks groups to compare Timbuktu and Venice (approved profiles). “Use the same criteria,” she says: location, trade goods, government, learning, links to other places. “Both were centres of trade and learning,” says Mei. “Timbuktu lay on the edge of the Sahara and the Niger, Venice on a lagoon,” says Abu. “But be careful,” says Ms Smith. “Two cases do not prove a rule about all cities. Say ‘in these two cities’, not ‘all cities’.”
Think: What new insight does comparing give that studying one city does not?
2. Understand: Comparative historical investigation
Idea 1: How to compare
A comparison examines how two or more cases are alike and different. Agree on criteria first (for example location, economy, government, culture and links). Collect evidence for each case, fill a matrix, then look for patterns.
Idea 2: Writing a balanced claim
Write claims such as “Both cities grew because of trade, but Timbuktu relied on caravans while Venice relied on ships.” Support with evidence from sources. A case study is a close look at one example. Be careful with generalisation: two cases do not prove a rule for all.
Idea 3: Reflecting
Comparison can reveal causes that a single case hides, challenge stereotypes and show connections. It can also mislead if cases are chosen unfairly or criteria favour one. Always say what the comparison cannot show and what else you would investigate.
3. Worked examples
Example 1 (I show you): Define
Generalisation.
- Think.
- Say.
- Check.
Answer: A broad statement from few examples.
Example 2 (We do it together): Define
Criteria.
- Think.
- Say.
- Check.
Answer: Points for fair comparison.
Example 3 (You try): Write
A balanced claim starter.
Show the steps and answer
- Think.
- Say.
- Check.
Answer: Both… but…
Did you know?
Historians who compare societies across the world are practising a field called comparative or world history.
Why this matters
Comparing teaches us that human societies share challenges and find different solutions.
4. Explore: Comparison matrix
Choose two approved cases (cities, empires, routes or technologies). Make a matrix with five criteria and evidence. Write three balanced claims and one caution about generalising. Present to the class.
- Choose.
- Fill.
- Write.
- Present.
Think about it: what did you notice?
What did you notice? Fair criteria make fair comparisons.

If a learner struggles
- Find the misconception: “The more different two cases are, the less they can be compared.” Difference is part of comparing.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a comparison 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 compares two societies from history. Please encourage fair thinking about similarities and differences. You do not need to be an expert to help.
- Compare fairly.
- Ask for evidence.
- Avoid stereotypes.
- 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 comparison, similarity, difference, case study, generalisation; plan a comparison; write balanced claims with evidence; avoid unfair generalisation.
Prerequisite knowledge. Grade 6 ideas: chronology, early societies, civilisations, trade routes and migration.
Materials. Profiles, matrices. 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 profiles and matrices.
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 two trading cities story.
Explanation (10 min). Teach comparison.
Guided activity (10 min). Comparison matrix.
Independent activity (10 min). Present.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. What can we learn by comparing societies from different places?
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. “The more different two cases are, the less they can be compared.” Difference is part of comparing.
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 comparison 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.
