Example: a simple lesson cycle using flexible grouping

1. Warm-up (5 min): Quick diagnostic quiz (5 items). Teacher notes patterns.
2. Group formation (2 min): Based on results:
   • Group 1 (remediate): 4 students, focused skill spiral.
   • Group 2 (practice): 5 students, guided worksheets + peer tutor.
   • Group 3 (extend): 3 students, problem-solving challenge.
3. Stations (25 min): Each station is 8–10 minutes. Teacher teaches Group 1 directly, circulates to Group 2, checks thinking in Group 3.
4. Regroup + share (8 min): Groups report one takeaway.
5. Exit ticket (5 min): Short problem that addresses the original objective.

Rotate groups next lesson so membership changes.

Quick decision flow (text version)

• Did a formative check show mixed readiness? → Yes → Consider grouping by readiness for a short reteach cycle.
• Is your goal to build discussion and transfer? → Yes → Use heterogeneous groups with clear roles.
• Is the problem motivational? → Yes → Use interest-based groups and high-success tasks to boost self-esteem.
• Is it about social or emotional skills? → Yes → Create small relational groups and coach soft skills explicitly.
