Teacher language
Adapt these prompts to the task and your learners.
Our purpose is: Build on an answer by adding a missing reason, a supporting detail or a justified qualification.
Show the relationship and explain the choice you made.
Try the new case on your own. Show the detail or reasoning that supports your answer.
Which support do you still need, and which part can you now do independently?
Across subjects
Maths: rehearse a method justification. Humanities: rehearse a source-based interpretation.
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.
