D4.4.3-5
Critique arguments.
Objective
Students will be able to name the flaw in an argument and say what would repair it.
Students are successful when they can
- Names the flaw in the reasoning.
- Says what would repair it.
- Criticises an argument they agree with.
What you need
- Eight written arguments, all flawed
- A short list of flaw types
- The printable practice sheet linked at the end of this plan
The lesson
Warm-up — agree and still object
5 min- Read an argument the class agrees with, supported by nothing.
- Ask whether agreeing makes it a good argument.
Teach — five ways an argument fails
18 min- 'The programme failed because the government was incompetent.' A cause with no evidence.
- 'The public wanted housing, so the policy was right.' Wanting does not establish a method works.
- 'Private firms would have built faster.' No evidence from where firms did build.
- 'He admitted it, so the government was honest throughout.' One instance, general conclusion.
- 'The 2011 book uses official figures, so it is right.' Both sides use those figures.
- For each, ask what would repair it rather than only naming the fault.
- Then the strength point: an argument that says what would refute it is testable.
“Does the reason actually get you to the claim?”
Guided practice — critique eight
17 min- Pairs name the flaw in eight arguments.
- For four they write the repair.
- Groups critique an argument they agree with.
Independent practice
12 min- Students complete the 'The Reason That Does Not Reach' page.
- Check the flaw is in the reasoning, not the conclusion.
Close
3 min- Ask which flaw the class commits most often.
What goes wrong, and why
Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.
Criticises the conclusion rather than the reasoning.
Why: Disagreement is the available response.
Fix: Ask whether the reason supports the claim. A conclusion you like can be badly argued.
Thinks admitting uncertainty is weakness.
Why: Confidence sounds convincing.
Fix: An argument that shows its limits can be tested. That is a strength.
Generalises from one instance.
Why: The instance is vivid.
Fix: One admission is one admission. Ask what pattern would be needed.
If they are not there yet
- Four arguments with the flaw type given.
- Choose the better of two repairs.
If they finish early
- Rewrite a flawed argument so it works.
- Find a flaw two of the eight share.
- Critique your own argument from the earlier lesson.
Exit ticket
'The 2011 book is right because it uses official figures.' What is wrong with that argument?
What to look for: Both sides use the same figures; the question is what they show. Saying only that it is wrong means the flaw is not yet named.

Questions about The Reason That Does Not Reach
How long does the The Reason That Does Not Reach lesson take?
55 minutes, split across 5 timed sections: warm-up 5 min, teach 18 min, guided practice 17 min, independent practice 12 min, close 3 min. The minutes are stated per section and add up to the stated length, so the plan can be cut or extended at a section boundary rather than abandoned halfway.
Which standard does The Reason That Does Not Reach teach?
D4.4.3-5 — D4.4.3-5, Communicating Conclusions and Taking Informed Action for Grade 3 to Grade 5: “Critique arguments.” In plain terms, judge how good an argument is.
What do I need to teach this lesson?
Eight written arguments, all flawed, a short list of flaw types and the printable practice sheet linked at the end of this plan. Everything listed is either ordinary classroom equipment or a free printable from this site — there is nothing to buy and nothing to prepare beyond photocopying.
What mistakes should I expect in this lesson?
Three, each a reasoning error rather than carelessness: criticises the conclusion rather than the reasoning; thinks admitting uncertainty is weakness and generalises from one instance. The plan gives the thinking behind each one and the teaching move that addresses the thinking rather than the symptom.
How do I know whether the lesson worked?
The exit ticket asks: “'The 2011 book is right because it uses official figures.' What is wrong with that argument?.” Both sides use the same figures; the question is what they show. Saying only that it is wrong means the flaw is not yet named. That tells you whether the class needs a reteach or a thirty-second conversation before you plan tomorrow.
Is there a worksheet to go with The Reason That Does Not Reach?
Yes — 1 printable D4.4.3-5 worksheet, linked at the end of the plan and free like the rest of the site. Each one comes with an answer key and 25 versions, so the practice after the lesson can be a different paper on every desk.

Yes. The plan, its printables and their answer keys are free to read, print and photocopy for your own class, with no account and no email capture. It was last reviewed on 7 September 2026. Please do not resell it or republish it as your own.
