The metal rod expanded because its temperature increased.
But → contrast
The metal rod expanded, but its mass remained the same.
So → consequence
The metal rod expanded, so it no longer fitted the gap.
A model to discuss and adapt to your class.
Science: metal heating
“The metal rod expanded because its temperature increased.” “The metal rod expanded, but its mass remained the same.” “The metal rod expanded, so it no longer fitted the original gap.”
02 · The classroom routine
Teach the move
Prepare · 3 minutes
Choose a short subject statement with enough context for cause, contrast and consequence. Prepare three endings to compare.
1
Start with the same statement and model a because ending that gives a cause or explanation.
2
Use but to introduce a genuine contrast or qualification.
3
Use so to express a consequence supported by the starting statement.
4
Pairs compare endings and reject one that sounds fluent but makes an inaccurate connection.
EAL upgrade
Remove the three labelled choices. Ask for a short explanation that uses whichever relationship the evidence needs.
Keep the subject challenge. Offer one model, visual or language prompt where needed, then check a fresh independent response.
03 · A plan for the next lesson
Try it tomorrow
Prepare one task
Choose a short subject statement with enough context for cause, contrast and consequence. Prepare three endings to compare.
Model and rehearse
Start with the same statement and model a because ending that gives a cause or explanation. Use but to introduce a genuine contrast or qualification.
Collect evidence
Give an unfamiliar statement. Ask learners to choose a connective and explain the relationship, then check that the science remains accurate.
Next time
Remove the three labelled choices. Ask for a short explanation that uses whichever relationship the evidence needs.
What to look for
Give an unfamiliar statement. Ask learners to choose a connective and explain the relationship, then check that the science remains accurate.
04 · Words you can use
Teacher language
Adapt these prompts to the task and your learners.
Launch
Our purpose is: Show how a connective changes the relationship between ideas and the thinking a sentence must express.
Probe the thinking
Does your ending explain a cause, introduce a contrast or show a consequence?
Check independently
Try the new case on your own. Show the detail or reasoning that supports your answer.
Hand over
Which support do you still need, and which part can you now do independently?
05 · Keep the move, change the context
Across subjects
Transfer 1
History: distinguish why an event occurred from what happened as a result.
Transfer 2
Maths: qualify a pattern with but by identifying a condition under which it does not hold.
Adjust language support
Use a small word bank, visuals and partner rehearsal when needed. Extend with precise explanations and qualifications. Judge the support from the response to this task.
Keep the strategy. Change the subject.
Four classroom examples
Adapt the content to your curriculum. These responses model the language and thinking to look for.
Science
Set up the task
Complete three versions of “The metal rod expanded” using because, but and so.
Possible student response
The rod expanded because it was heated; it expanded, but its mass stayed the same; it expanded, so it no longer fitted the gap.
Check the learning
Check cause, contrast and consequence separately.
Humanities
Set up the task
Use three connectors to explore the growth of an industrial town.
Possible student response
The town grew because factories attracted workers. It grew, but housing was overcrowded. It grew, so demand for services increased.
Check the learning
Ask learners what evidence would support each relationship.
English
Set up the task
Connect a character’s silence to three different relationships.
Possible student response
She stayed silent because she feared rejection. She stayed silent, but her gesture revealed anger. She stayed silent, so the others misunderstood her.
Check the learning
Check each claim against the actual passage.
Maths
Set up the task
Use the stem “The triangle is isosceles” with three connectors.
Possible student response
It is isosceles because two sides are equal. It is isosceles, but it is not necessarily equilateral. It is isosceles, so its base angles are equal.
Check the learning
Ask why the contrast statement needs “not necessarily”.
