Student lesson

  3. Check the link.
  4. Avoid exaggeration.

Words to know

logic
careful reasoning step by step
generalisation
a broad statement based on a few cases
relevant
closely connected to the point
faulty reasoning
reasoning that does not truly support the claim

1. Discover: Good and weak reasons

Claim: Our class should recycle paper.

Strong reason: Recycling saves trees, because paper is made from wood. Weak reason: Everybody likes recycling, (a generalisation with no evidence). Weak reason: Recycling is good because my cousin does it. (faulty reasoning: it is not relevant).

Think: Why is the first reason strong?

2. Understand: Does it follow?

Idea 1: Logic

Logic links each reason to the claim in a way that makes sense step by step.

Idea 2: Relevant reasons

A strong reason is relevant and backed by facts.

Idea 3: Errors

Avoid generalisation (everybody, always, never) and faulty reasoning that does not prove the claim.

Remember: Use relevant reasons that follow logically, and avoid sweeping statements and faulty links.

3. Worked examples

Example 1 (I show you): Strong

Which reason is strong?

  1. Saves trees.

Answer: recycling saves trees because paper is made from wood

Example 2 (We do it together): Generalisation

Which is a generalisation?

  1. Everybody.

Answer: everybody likes recycling

Example 3 (You try): Faulty

Why is the cousin reason weak?

Show the steps and answer
  1. Not relevant.

Answer: what a cousin does does not prove recycling is good

Did you know?

Words such as always, never and everyone often signal an unsupported generalisation.

Why this matters

Logical reasoning makes your arguments trustworthy.

4. Explore: Check the logic

Test reasons.

  1. Write a claim.
  2. Write three reasons.
  3. Mark strong and weak ones.
  4. Improve the weak ones.
Think about it: what did you notice?

You can reason logically.

5. Practise

Use these starters when you talk about the lesson. Say them out loud.

  • This reason is strong because ___.
  • This is a generalisation because ___.
  • It does not follow because ___.
  • A better reason is ___.

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: link reasons to claims; order reasons logically; spot weak reasoning; avoid overgeneralising.

Prerequisite knowledge. Opinion and persuasive writing.

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.
