D4.2.3-5
Construct explanations using reasoning, correct sequence, examples, and details with relevant information and data.
Objective
Students will be able to explain a change in order with reasoning and a source at each step.
Students are successful when they can
- Puts the steps in order.
- Writes the reasoning between steps.
- Names a source at each step.
What you need
- Step cards for the housing shortfall
- The white paper, broadcast and council report
- The printable practice sheet linked at the end of this plan
The lesson
Warm-up — the explanation backwards
5 min- Read an explanation with the shortfall first and the target last.
- Ask why it is hard to follow.
Teach — order, joins, sources
18 min- Lay the steps: destruction counted, target set, materials short, homes fall behind.
- Ask what is missing between step three and step four: the reasoning that connects them.
- Write the joins in: because bricks and timber ran short, sites stood idle.
- Add a source at each step: white paper, white paper, broadcast, council report.
- Ask why sourcing each step matters: a reader can check the reasoning one step at a time.
- Cut a detail that serves no step and say why cutting improves it.
- Say the difference from an argument: this says how, not what you should think.
“What connects this step to the next, and where would I check it?”
Guided practice — write the joins
17 min- Pairs order five steps for a second explanation.
- They write the join between each pair and name a source.
- Groups cut one unnecessary detail from each explanation.
Independent practice
12 min- Students complete the 'Show How It Came About' page.
- Check the joins are present, not just the steps.
Close
3 min- Read the explanation with the clearest joins.
What goes wrong, and why
Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.
Lists steps with no reasoning between them.
Why: The list looks complete.
Fix: Ask 'and therefore?' between each pair. The answer is the join.
Sources the conclusion and not the steps.
Why: The conclusion is what matters.
Fix: A reader checks steps. Source each one.
Writes an argument instead.
Why: Both use evidence.
Fix: Check what the task asked. Explanation says how; argument says what to think.
If they are not there yet
- Four steps in order with one join to write.
- Choose the join from two options.
If they finish early
- Explain the same change starting from a different first step.
- Add a step the explanation is missing.
- Say which join is weakest and why.
Exit ticket
Explain why 140,000 homes were built rather than 300,000, with the steps in order and a source at each.
What to look for: Target set, materials short, sites delayed, completions fall short — with joins and sources. A bare list means the joins need another run.

Questions about Show How It Came About
How long does the Show How It Came About 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 Show How It Came About teach?
D4.2.3-5 — D4.2.3-5, Communicating Conclusions and Taking Informed Action for Grade 3 to Grade 5: “Construct explanations using reasoning, correct sequence, examples, and details with relevant information and data.” In plain terms, explain something with reasoning, the right order, examples and detail.
What do I need to teach this lesson?
Step cards for the housing shortfall, the white paper, broadcast and council report 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: lists steps with no reasoning between them; sources the conclusion and not the steps and writes an argument instead. 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: “Explain why 140,000 homes were built rather than 300,000, with the steps in order and a source at each.” Target set, materials short, sites delayed, completions fall short — with joins and sources. A bare list means the joins need another run. That tells you whether the class needs a reteach or a thirty-second conversation before you plan tomorrow.

Yes — 1 printable D4.2.3-5 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.
