Four-Sentence Explanation
Build a concise explanation through four turns: idea, evidence, reasoning and limitation.
Worked classroom example
Science
A group explains a result, cites a measurement, gives a reason and notes one limitation.
Use this example to make the language move visible. Select subject content appropriate to the class’s age and prior knowledge.
Teaching sequence
- Set up four role or sentence cards; name the subject question and show a short model of the task.
- Learners build a concise explanation through four turns: idea, evidence, reasoning and limitation. Give quiet thinking time before pairs or groups compare what they noticed.
- Ask each learner to share or record one independent response. Use the example from Science to check the idea, then fade one prompt on the next attempt.
Materials and purpose
four role or sentence cards
This gives learners time to prepare a point and a clear reason to contribute. The structure supports participation while leaving the ideas and reasoning in their hands.

Prepare
Use four role or sentence cards. Choose a second example that checks the same language move without repeating the original answer.
Classroom task
Build a concise explanation through four turns: idea, evidence, reasoning and limitation.
Check independent transfer
Ask each learner to share or record one independent response. Use the example from Science to check the idea, then fade one prompt on the next attempt.
Collect a response on fresh content. Note what was achieved without the model, partner or teacher prompt, then choose one next teaching step.
Teacher language
Teacher language
How would this change in a different subject example?
“What would help your listener follow that explanation?”
“How would you revise your response after that question?”
Respond to the learner
Identify one successful meaning or language choice. Ask about one gap, allow thinking time, then invite a revision. Check the revised move again on a fresh example.
Adjust support and challenge
Offer a brief model, useful vocabulary and partner rehearsal where needed. Keep the subject goal; reduce one prompt on fresh content and record what was independent.

More support
Offer thinking time, a small phrase bank and a clear listener role. Collect an individual explanation after paired rehearsal. Allow familiar-language notes or another response mode when checking subject understanding.
Greater independence
Change the content, evidence or audience. Remove the completed model and ask learners to explain a choice. Increase subject complexity only when it fits the curriculum and prior knowledge.
Choose the next step
If subject meaning is insecure, reteach the concept. If the concept is understood but the English is unclear, model one useful language relationship and invite a fresh response.
