Teacher language
Adapt these prompts to the task and your learners.
Our purpose is: One learner gives a solution; the checker asks for the reason behind each step.
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
Science: explainer and evidence checker. Humanities: source interpreter and challenge questioner.
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.
