Lesson Plan Forge

Spec

Build Lesson Plan Forge — a plan a teacher can run tomorrow, not a unit of busywork.

PRODUCT
Inputs: topic, age/grade, minutes (20 / 45 / 90), constraints chips (no video, mixed ability, no worksheet, no phones, ELL-friendly). Output a timed lesson + analog variant + misconception list.

LESSON STRUCTURE (always)
- Objective: one sentence, observable
- Hook (time-boxed)
- Teach (time-boxed)
- Guided practice
- Independent (or paired)
- Exit ticket (3 items max, actually answerable in 4 minutes)
- Materials: short list, ordinary classroom stuff unless the user named a lab
- Misconceptions: 3, each with the tell and the redirect
- Analog variant: the same lesson with no screens
- Differentiation: one stretch, one support, not a novel

TIMING
Every block has minutes, and they must sum to the selected total ±1. Show a live sum. If the model overruns, the UI refuses to present it until tightened.

SCREENS
1. Brief
2. Plan (print-friendly)
3. Board — a timeline of blocks the teacher can glance at while walking

EMPTY
Sample: “why the moon has phases”, grade 6, 45 min, no video.

VISUAL
Teacher desk. Paper-first. Wide print stylesheet. Mono for times, sans for talk-tracks. No cartoon mascots, no gold stars, no purple.

OUT OF SCOPE
Standards-database sync, LMS export, generating a 20-page worksheet pack, student accounts.

ACCEPTANCE
- 45-minute sample sums to 45.
- Analog variant does not mention a projector.
- Exit ticket has ≤3 items.
- Print is readable in black and white.
