Only one student should talk at any time, and no students should work ahead whilst ignoring the discussion. Regular reminders to stop and listen are needed to maintain focus. Accountability for listening requires multiple techniques. [[Cold-Call]] can be used to ask students to repeat what another student said, catching those not paying attention through listening checks. Feedback should address both the student and their work. Follow-up with previously accountable students ensures improvement. ## Discussion techniques Beyond managing attention, effective discussions require gathering and building upon multiple student contributions. Take many answers from different students, ask whether they agree or disagree with previous responses, and build on student thinking rather than immediately evaluating contributions. When students give almost correct answers, ask the class to [[Turn and Talk]] about what could be added to complete the answer. Maintain standards by refusing to [[Don't Round Up|round up]], pushing for precise and complete answers. [[No Opt-Out|Opt-out]] is not permitted; all students must engage with the thinking. ## Implementation guidelines Before discussion, ensure all students are ready to listen and participate. During discussion, monitor for engagement and redirect attention as needed. Afterwards, check that key points were understood across the class. The focus should remain on substance over participation: discussions should advance mathematical understanding rather than just generate talk. ## References Cazden, C. B.
