Student lesson

The lesson in 60 seconds

  1. Find the claim.
  2. Check the reasoning.
  3. Name any fallacy.
  4. Repair it.

Words to know

fallacy
a flaw in reasoning
hasty generalisation
a broad claim from too little evidence
personal attack
attacking the person instead of the argument
either/or thinking
pretending there are only two options

1. Discover: Flawed arguments

Kemi hears: “Two pupils from Class A were late, so Class A is always late.” (hasty generalisation) “You cannot argue about homework; you never do yours!” (personal attack) “Either we ban all phones or the school will fall apart.” (either/or thinking) “I wore my lucky socks and we won, so the socks caused it.” (false cause)

Each is a fallacy: a flaw in reasoning. Kemi fixes them with evidence and fairness.

Think: Why are these arguments weak?

2. Understand: Spotting weak reasoning

Idea 1: Fallacies

A fallacy is a flaw in reasoning that can fool readers.

Idea 2: Common ones

Hasty generalisation, personal attack, either/or thinking, false cause.

Idea 3: Repair

Repair fallacies with more evidence, fair claims and attention to the argument itself.

Remember: Evaluate reasoning by spotting fallacies and repairing them with evidence and fairness.

3. Worked examples

Example 1 (I show you): Generalisation

Which is hasty?

  1. Class A always late.

Answer: two late pupils so class a is always late

Example 2 (We do it together): Attack

What is a personal attack?

  1. You never do homework.

Answer: attacking the person not the argument

Example 3 (You try): Either/or

What is wrong with either/or?

Show the steps and answer
  1. Only two options.

Answer: it pretends there are only two options

Did you know?

Learning fallacies helps you spot weak adverts and speeches.

Why this matters

Evaluating reasoning makes you a critical thinker.

4. Explore: Fallacy finder

Spot fallacies.

  1. Read arguments.
  2. Name the claim.
  3. Name any fallacy.
  4. Fix the reasoning.
Think about it: what did you notice?

You can evaluate reasoning.

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

  1. Find the misconception: Rushing without checking. Slow down and check your work.
  2. Explain another way: use real objects, pictures or actions first, then words.
  3. Show a simpler example: Re-read the examples slowly and use the sentence frames.
  4. Guided practice: work through one example together and let the learner try the next one.
  5. Reassess: use the quiz again or the worksheet.
  6. Move on when the learner shows Silver-level evidence independently.

For parents and guardians

In this lesson your child practises a key Grade 3 English skill with clear examples and a quiz. You do not need to be an expert to help.

  • Listen while your child explains the idea.
  • Ask for one new example.
  • Praise effort and careful work.
  • 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 fallacy; spot common fallacies; explain why they are flawed; fix flawed reasoning.

Prerequisite knowledge. Revising arguments.

Materials. Chart paper or board, pencils, picture or word cards, a reading book if available. 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. Write the key words and examples on the board or on cards before the lesson.

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). Introduce the idea with the opening example.

Explanation (10 min). Teach the key words.

Guided activity (10 min). Practise together.

Independent activity (10 min). Check understanding with the quiz.

Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.

Key questions. What is the key idea? Can I give my own example?

Teacher explanation notes. Move from the spoken word to pictures and then to print. Read aloud often, point to the words, and let learners hear and say before they read and write.

10–12. Differentiation, formative assessment, common misconceptions

Support. Use the sentence frames and work with a partner. Extension. Create a harder example of your own.

Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.

Misconceptions. Rushing without checking. Slow down and check your work.

13–15. Assessment questions, answer keys, marking scheme

Use the quiz, the 11-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. Re-read the examples slowly and use the sentence frames. Enrichment. Make up your own example and teach it to someone at home. 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.
