Agree, Extend, Challenge
Learners choose one move to respond to a peer: agree with a reason, extend the point or challenge it with evidence.
Worked classroom example
Geography
Discuss whether a map supports one explanation of settlement patterns.
Use this example to make the language move visible. Select subject content appropriate to the class’s age and prior knowledge.
Teaching sequence
- Prepare a prompt and three response moves and share the purpose: academic discussion. Keep the source or subject question visible.
- Learners choose one move to respond to a peer: agree with a reason, extend the point or challenge it with evidence.
- Ask learners to show the clue, language choice or evidence they used. Invite one partner to check it, then finish with an independent response.
Materials and purpose
a prompt and three response moves
A small repertoire of moves gives discussion direction without scripting thought.

Prepare
Use a prompt and three response moves. Choose a second example that checks the same language move without repeating the original answer.
Classroom task
Learners choose one move to respond to a peer: agree with a reason, extend the point or challenge it with evidence.
Check independent transfer
Ask learners to show the clue, language choice or evidence they used. Invite one partner to check it, then finish with an independent response.
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
What did you notice about academic discussion, and what evidence helped you decide?
“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.
