Monitoring progress & adjusting pace (practical cues)

• Set two daily checkpoints: mid‑lesson formative check and exit ticket. If >30% fail, pause/retireach next lesson.
• Use quick metrics: % correct on mini‑quiz, number of Post‑its with similar misconceptions, rubric band counts.
• Flexible time blocks: mark one practice block as “flex” (can be shortened or extended).
• Backup plan options: (1) compressed reteach mini‑lesson, (2) extension tasks for fast groups, (3) home practice folder or video.
• When to slow down: when multiple groups show the same conceptual error, low engagement, or repeated procedural mistakes.
• When to speed up: mastery checks show >80% accuracy and students ask for more challenge.

Differentiation & grouping protocols

• Use diagnostic to make initial groups (homogeneous for remedial, heterogeneous for mixed tasks).
• Rotate group roles: researcher, presenter, recorder, quality controller (supports equal participation).
• Offer tiered tasks: core (must master), stretch (deeper reasoning), extension (transfer).
• Use assistant‑teacher model: those who demonstrate mastery act as helpers for weaker groups. Justification: peer help consolidates mastery and scales teacher capacity.
