Student lesson
- A claim answers the question.
- Evidence supports it.
- Reasoning links them.
- Events have several causes.
Words to know
a statement that answers a question and needs support
information from sources that supports a claim
the explanation that links the evidence to the claim
something that helps make an event happen
1. Discover: Explaining a change
Mei wants to explain why a market town grew. Her claim: “Bo grew into a busy town because it is a trading centre.” Her evidence: a map shows roads meeting there, and a book says traders bring goods from farms to sell. Her reasoning: “Roads help people and goods reach one place, so many people come to buy and sell, so the town grows.” Mr Cole adds, “Good. Can you think of other causes?”
Think: Which of Mei’s causes is long-term and which is short-term?
2. Understand: Historical explanations
Idea 1: Claim, evidence, reasoning
A strong explanation has three parts. The claim answers the question. The evidence comes from sources. The reasoning explains how the evidence supports the claim. Write them in order and link them with words such as “because”, “this shows that” and “therefore”.
Idea 2: Causes and consequences
A cause helps make something happen. Long-term causes build up over years; short-term causes act close to the event. Most events have several causes and many consequences, some quick and some slow. Sort causes into groups such as people, geography, money and ideas.
Idea 3: Careful and honest
Use careful language: “probably”, “the evidence suggests”, “one important cause was”. Name what you do not know and what evidence would help. Check that each point has a source and that your conclusion answers the question you asked at the start.
3. Worked examples
Example 1 (I show you): Name
The three parts of an explanation.
- Think.
- Say.
- Check.
Answer: Claim, evidence, reasoning.
Example 2 (We do it together): Sort
A cause that builds over years: long-term or short-term?
- Think.
- Say.
- Check.
Answer: Long-term.
Example 3 (You try): Write
A careful phrase.
Show the steps and answer
- Think.
- Write.
- Check.
Answer: The evidence suggests.
Did you know?
Historians often disagree about which cause was most important, and they make their case by weighing evidence.
Why this matters
Explaining with evidence and reasoning helps you think clearly and be convincing and fair.
4. Explore: Build the explanation
Choose a safe historical question. Write a claim, two pieces of evidence with references, reasoning that links them, one long-term and one short-term cause, and a careful conclusion. Swap with a partner for kind feedback.
- Claim.
- Evidence.
- Reasoning.
- Share.
Think about it: what did you notice?
What did you notice? Reasoning made the claim stronger.
5. Practise

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: “Events have one cause.” Most have several.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a CER card.
- 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 writes an explanation from evidence. Please ask them to say how they know. You do not need to be an expert to help.
- Ask how they know.
- Praise clear reasons.
- Look for more causes.
- 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 claim, evidence, reasoning, cause; build a claim-evidence-reasoning explanation; distinguish causes; use careful language.
Prerequisite knowledge. Grade 5 ideas: enquiry, primary and secondary sources, oral history and written records.
Materials. Paper, source cards. 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 cards.
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 explaining a change story.
Explanation (10 min). Teach evidence-based explanations.
Guided activity (10 min). Build the explanation.
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 we build a clear explanation of the past from evidence?
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. “Events have one cause.” Most have several.
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 CER card. 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.
