Learn one hard idea properly in an hour
Builds a one-hour path through a concept you keep bouncing off: the minimum prerequisite, the idea itself, the two places your intuition will be wrong, and a test.
Plans one lesson three ways at once — for the students who are behind, on track, and ahead — without turning it into three lessons you have to run simultaneously.
Plan one lesson. TOPIC: {{TOPIC}} THE RANGE IN THE ROOM: {{SPREAD}} CONSTRAINTS: {{CONSTRAINTS}} Produce: **1. The one idea.** If they remember a single thing in a year, what is it? One sentence, in student language. **2. The misconception.** The wrong belief students at this level reliably arrive with, and the specific moment in the lesson that confronts it. **3. The spine.** A minute-by-minute run of the lesson that works for the middle of the room. Include what I am doing and what they are doing. **4. Two adjustments, not two lessons.** One thing to change for the students who are behind and one for those ahead — each an adjustment to the *same* activity, not a separate task I would have to supervise in parallel. **5. The check.** A question I can ask in the last four minutes that tells me who actually got it. It must be answerable in one sentence and must not be answerable correctly by someone who only half-followed. Rules: - Do not produce a worksheet. Produce a plan. - Do not assume equipment beyond the constraints I gave. - Do not use "differentiation" or "scaffolding" as if naming them explains them — describe the actual adjustment. - If 50 minutes is not enough for this topic, say what to cut.

# A lesson plan for a class that isn't at one level
Plans one lesson three ways at once — for the students who are behind, on track, and ahead — without turning it into three lessons you have to run simultaneously.
## Inputs to collect first
Ask the user for anything below that they have not already given you. Do not
invent values for these.
- `TOPIC` — What you're teaching, and to whom. (e.g. Photosynthesis, Year 8, 50 minutes.)
- `SPREAD` — The honest range in the room. (e.g. Six students still shaky on cell structure; most fine; four already read ahead.)
- `CONSTRAINTS` — Time, materials, room, anything fixed. (e.g. No lab access. One projector. Must include a written assessment.)
## Instructions
Plan one lesson.
TOPIC: {{TOPIC}}
THE RANGE IN THE ROOM: {{SPREAD}}
CONSTRAINTS: {{CONSTRAINTS}}
Produce:
**1. The one idea.** If they remember a single thing in a year, what is it?
One sentence, in student language.
**2. The misconception.** The wrong belief students at this level reliably
arrive with, and the specific moment in the lesson that confronts it.
**3. The spine.** A minute-by-minute run of the lesson that works for the
middle of the room. Include what I am doing and what they are doing.
**4. Two adjustments, not two lessons.** One thing to change for the students
who are behind and one for those ahead — each an adjustment to the *same*
activity, not a separate task I would have to supervise in parallel.
**5. The check.** A question I can ask in the last four minutes that tells me
who actually got it. It must be answerable in one sentence and must not be
answerable correctly by someone who only half-followed.
Rules:
- Do not produce a worksheet. Produce a plan.
- Do not assume equipment beyond the constraints I gave.
- Do not use "differentiation" or "scaffolding" as if naming them explains them
— describe the actual adjustment.
- If 50 minutes is not enough for this topic, say what to cut.
## Notes from people who use this
- Section 4's constraint — adjustments, not parallel tasks — is what makes this survive contact with a real classroom.
- The exit check is the most reusable output. Build a bank of them.
- Give it the honest spread. 'Mixed ability' produces a generic plan; 'six shaky on cell structure' produces a usable one.

Ask for a differentiated lesson plan and you get three lessons, which is useless — nobody can run three lessons at once. The constraint that both adjustments modify the same activity is what makes the output something you could actually teach on Monday.
This is where models genuinely help: they have seen an enormous number of students get the same thing wrong in the same way, and naming that wrong belief before it forms saves the reteach.

Turns your messy notes into a testing session rather than a summary — it quizzes you, marks you honestly, and tells you which parts you only think you know.
