- Names what is missing.

The lesson
Warm-up — because of the war
5 min- Read: 'the target was missed because of the war'.
- Ask what a reader still does not know.
Teach — four ways an explanation fails
18 min- Order: the admission stated before the shortfall it admits.
- Missing steps: 'because of the war' skips which materials and why that slowed building.
- Missing sources: every step asserted and none checkable.
- Too much detail: every figure in the council report, and the reasoning buried.
- Ask what makes an explanation with two causes honest rather than vague.
- Answer it: saying which is which, and that the evidence cannot separate them.
- Then the distinction again: explanation says how; argument says what to think.
“Which step could a reader not follow, or not check?”
Guided practice — repair eight
17 min- Pairs name what is missing from eight explanations.
- For four they write the missing step or source.
- Groups find the one that is really a faulty argument.
Independent practice
12 min- Students complete the 'Reasoning You Cannot Follow' page.
- Check the repair supplies reasoning rather than more words.
Close
3 min- Ask which fault is hardest to spot in your own writing.
What goes wrong, and why
Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.
Thinks more detail improves an explanation.
Why: Detail signals effort.
Fix: Detail with no step to serve buries the reasoning. Ask what each figure is for.
Judges an explanation by agreement.
Why: Agreement is the habitual response.
Fix: An explanation is not asking for agreement. Ask whether the steps follow.
Treats an explanation with two causes as vague.
Why: One cause is tidier.
Fix: Saying which is which, and that they cannot be separated, is precise.
If they are not there yet
- Four explanations with the fault named.
- Choose the missing step from two options.
If they finish early
- Rewrite a faulty explanation completely.
- Turn one into an argument and say what changed.
- Critique your own explanation from the earlier lesson.
Exit ticket
'The target was missed because of the war.' What is missing, and what would you add?
What to look for: Which materials ran short, why that slowed building, and a source for each step. Saying only that it is vague means the repair step is missing.

Questions about Reasoning You Cannot Follow
How long does the Reasoning You Cannot Follow 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 Reasoning You Cannot Follow teach?
D4.5.3-5 — D4.5.3-5, Communicating Conclusions and Taking Informed Action for Grade 3 to Grade 5: “Critique explanations.” In plain terms, judge how good an explanation is.
What do I need to teach this lesson?
Eight explanations, each faulty, the white paper, broadcast and council report as checks 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: thinks more detail improves an explanation; judges an explanation by agreement and treats an explanation with two causes as vague. 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 target was missed because of the war.' What is missing, and what would you add?.” Which materials ran short, why that slowed building, and a source for each step. Saying only that it is vague means the repair step is missing. That tells you whether the class needs a reteach or a thirty-second conversation before you plan tomorrow.
