Student lesson
- Credible sources have expertise and evidence.
- Popular does not mean accurate.
- Dates and independence matter.
- Reliability depends on the question.
Words to know
how far a source can be believed
how far a source can be depended on to be accurate and consistent
special knowledge or skill gained through study or experience
checking that information is true
1. Discover: The viral claim
Ms Smith shows a made-up claim shared by thousands: “Rivers in the country will dry up next year.” “How many people shared it?” she asks. “Thousands,” says Abu. “Who wrote it?” Nobody knows. “What evidence does it give?” None. “A national water agency report, from last month, with data and named scientists, says water levels vary by season,” she says. “Which is more credible?” Popular is not the same as accurate.
Think: What are the first three questions you would ask about any claim?
2. Understand: Credibility and reliability
Idea 1: Tests of credibility
Credibility is how far a source can be believed. Tests: Does the author have expertise? Is evidence given? Is it up to date? Is the source independent, or does it gain from the claim? Do other sources agree? Can the facts be checked?
Idea 2: Not just popular
A claim is not true because many people share it, because it sounds confident, or because it comes from someone famous. Verification means checking with trusted sources, original documents or data. Be careful with sources that hide who wrote them.
Idea 3: Reliability
Reliability means a source can be depended on, and it depends on the question. A local elder may be highly reliable about the history of a village but not about world trade. Rate sources high, medium or low and give reasons.
3. Worked examples
Example 1 (I show you): Define
Credibility.
- Think.
- Say.
- Check.
Answer: How far a source can be believed.
Example 2 (We do it together): Define
Verification.
- Think.
- Say.
- Check.
Answer: Checking something is true.
Example 3 (You try): Name
A test of credibility.
Show the steps and answer
- Think.
- Say.
- Check.
Answer: Author expertise.
Did you know?
Fact-checking organisations around the world trace claims back to their original evidence.
Why this matters
Checking credibility protects us from errors and from being misled.
4. Explore: Credibility rating
Rate three made-up sources on one claim using five tests. Give each a rating (high, medium or low) with two reasons. Decide what extra evidence you would seek.
- Test.
- Rate.
- Explain.
- Share.
Think about it: what did you notice?
What did you notice? Evidence beats confidence.

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: “If many people say it, it is true.” Check evidence.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a credibility 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 learns to check claims. Please practise checking sources together. You do not need to be an expert to help.
- Check before sharing.
- Ask for evidence.
- Use trusted sources.
- 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 credibility, reliability, expertise, accuracy, verification; apply credibility tests; distinguish credible from popular; rate sources with reasons.
Prerequisite knowledge. Grade 5 ideas: public issues, research questions, evidence, perspectives and presenting findings.
Materials. Claim 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 claim 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 viral claim story.
Explanation (10 min). Teach credibility.
Guided activity (10 min). Credibility rating.
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 can we decide whether a source can be trusted?
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. “If many people say it, it is true.” Check evidence.
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 credibility 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.
