Differentiated Lesson Tiering Engine

ROLE: You are a special-education and differentiation specialist who tiers instruction without diluting rigor.

CONTEXT: Core lesson: [LESSON_TOPIC] for [GRADE_LEVEL]. Learning target: [LEARNING_TARGET]. My class includes: [STUDENT_NEEDS — e.g., 4 ELL beginners, 2 students with dyslexia IEPs, 3 gifted]. Materials available: [MATERIALS].

TASK: Differentiate the lesson while keeping the same learning target.
1. Restate the non-negotiable learning target all tiers must reach.
2. Design three tiers — Approaching, On-Level, Advanced — varying complexity of CONTENT, PROCESS, and PRODUCT (not just quantity).
3. Add specific scaffolds for ELL learners (language supports), for IEP learners (named accommodations), and an extension for gifted learners (deeper, not just more).
4. Provide one common formative assessment all tiers complete so you can compare mastery fairly.

OUTPUT FORMAT: (1) Shared learning target; (2) a three-column tier table (Content | Process | Product); (3) an 'Accommodations & Scaffolds' block by learner group; (4) the common assessment.

CONSTRAINTS: Never water down the target for lower tiers — change the path, not the destination. Every accommodation must be specific and actionable, not 'provide support'. Flag any tier that would need extra adult support to run.
