Likely Causes and Likely Effects
A 45-minute Grade 3 lesson on separating what caused a change from what followed it.
Likely Causes and Likely Effects is a free 45-minute Grade 3 to Grade 5 social studies lesson plan for Common Core standard D2.His.14.3-5 — explain the likely causes and effects of an event. It is timed across 5 sections, gives the exact wording to use where the wording carries the mathematics, names 3 misconceptions with the teaching move that addresses each, and ends with an exit ticket and a printable worksheet with its answer key.

D2.His.14.3-5
Explain probable causes and effects of events and developments.
Objective
Students will be able to sort statements into causes and effects of one historical change.
Students are successful when they can
- Sorts statements into cause and effect.
- Uses the dates to check the sort.
- Says why one thing following another is not proof it was caused.
What you need
- Twelve statement cards about the railway
- The dated sources as a check
- The printable practice sheet linked at the end of this plan
The lesson
Warm-up — before or after
5 min- Hold up 'investors expected profit' and 'the workhouse filled'.
- Ask which came before 1846 and which after.
Teach — order first, then argue
15 min- Sort three causes: an Act was passed, rail carried goods faster, towns needed coal.
- Sort three effects: wharf labourers fell to four, admissions rose, streets grew by the station.
- Say the first check: a cause must come before. Use the dates in the sources.
- Then the harder point: coming after is not enough. Bad weather in 1847 also came after.
- Ask what makes the admissions a probable effect: the register records canal work ending.
- Name the word 'probable' and say why historians use it.
“Did it come before, and is there a mechanism connecting them?”
Guided practice — sort twelve
13 min- Pairs sort twelve cards into cause and effect.
- They check three against the dated sources.
- Groups find one card that came after but was probably not caused by the railway.
Independent practice
9 min- Students complete the 'Causes on One Side, Effects on the Other' page.
- Check for the date check being used.
Close
3 min- Ask which effect took longest to appear.
What goes wrong, and why
Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.
Treats anything after as an effect.
Why: Sequence looks like causation.
Fix: Name a mechanism. Without one it is coincidence.
Thinks a change has one cause.
Why: Single causes are easier to remember.
Fix: The Act, the speed and the demand for coal are all causes. List them together.
Avoids the word probable.
Why: It sounds uncertain and therefore weak.
Fix: It is precise. We have strong evidence and not proof, and saying so is the honest claim.
If they are not there yet
- Six cards, three of each kind.
- Give the date and ask which side it falls on.
If they finish early
- Find an effect that became a cause of something else.
- Say which cause was necessary and which merely helped.
- Argue that one listed effect had another cause entirely.
Exit ticket
Workhouse admissions rose after 1846. What makes that a probable effect of the railway rather than a coincidence?
What to look for: The register records canal work ending, which the railway caused. 'It came after' alone means the mechanism step is missing.

Questions about Likely Causes and Likely Effects
How long does the Likely Causes and Likely Effects lesson take?
45 minutes, split across 5 timed sections: warm-up 5 min, teach 15 min, guided practice 13 min, independent practice 9 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 Likely Causes and Likely Effects teach?
D2.His.14.3-5 — D2.His.14.3-5, History for Grade 3 to Grade 5: “Explain probable causes and effects of events and developments.” In plain terms, explain the likely causes and effects of an event.
What do I need to teach this lesson?
Twelve statement cards about the railway, the dated sources as a check 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: treats anything after as an effect; thinks a change has one cause and avoids the word probable. 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: “Workhouse admissions rose after 1846. What makes that a probable effect of the railway rather than a coincidence?.” The register records canal work ending, which the railway caused. 'It came after' alone means the mechanism step is missing. 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 Likely Causes and Likely Effects?
Yes — 1 printable D2.His.14.3-5 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.
Is Likely Causes and Likely Effects free to use?
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.
