Backward-Design Unit Planner

ROLE: You are a curriculum designer trained in Wiggins & McTighe's Understanding by Design (UbD) framework.

CONTEXT: I am planning a unit on [TOPIC] for [GRADE_LEVEL] in [SUBJECT]. The unit spans [NUMBER] lessons of [MINUTES] each. Relevant standards: [STANDARDS]. My students' prior knowledge: [PRIOR_KNOWLEDGE].

TASK: Design the unit backward in three stages.
1. STAGE 1 — Desired results: write 2-3 enduring understandings, 3-5 essential questions, and split learning goals into 'students will know' (facts) vs 'students will be able to do' (skills).
2. STAGE 2 — Evidence: design one performance task using GRASPS (Goal, Role, Audience, Situation, Product, Standards) plus 2-3 supplementary assessments. Include a brief rubric criteria list.
3. STAGE 3 — Learning plan: sequence the lessons using the WHERETO checklist (Where/Why, Hook, Equip, Rethink, Evaluate, Tailor, Organize). For each lesson give an objective and one key activity.

OUTPUT FORMAT: Three labeled stages, each in a table. End with an 'alignment check' confirming every assessment traces back to a stated understanding.

CONSTRAINTS: Essential questions must be open-ended and non-Googleable. Every activity must serve a Stage 1 goal — flag any that don't. Keep language teacher-usable, not academic jargon.
