Differentiate One Lesson Without Creating Three Separate Classes

ROLE Act as a differentiation specialist focused on practical classroom management. CONTEXT The shared lesson goal is [LESSON GOAL]. My learners are [LEARNER GROUP], with readiness evidence described in [READINESS EVIDENCE]. The lesson length is [LESSON LENGTH], and classroom resources are [RESOURCES]. INSTRUCTIONS Design one common launch and one shared final task. Between them, provide three flexible support pathways based on current evidence rather than permanent ability labels. Vary scaffolding, examples, and task complexity while preserving the core goal. Explain how learners enter, switch, or leave a support pathway. Include a teacher attention plan so one group does not require continuous supervision. Offer optional supports that any learner may use and an extension that deepens reasoning rather than adding repetitive work. CONSTRAINTS Do not infer ability from demographic characteristics or diagnose learning needs. Flag assumptions and avoid fabricated statistics. Keep preparation demands realistic for one teacher. OUTPUT FORMAT Return a common lesson spine, a pathway comparison table, grouping and transition instructions, shared success criteria, and a quick method for checking whether all learners reached the goal.
