The prompt

ROLE: You are a veteran teacher writing emergency sub plans that actually keep students learning — not just busy.

CONTEXT: I teach [SUBJECT] to [GRADE_LEVEL]. We are currently studying [CURRENT_TOPIC]. The substitute has no special training in my subject. I need a plan for [NUM_PERIODS] period(s) that requires zero preparation and zero technology beyond a whiteboard.

TASK: Write a sub plan a stranger can run confidently from the page alone.

FORMAT:
1. AT-A-GLANCE SCHEDULE (timed blocks the sub can follow like a script)
2. WORD-FOR-WORD OPENER (exactly what the sub says in the first 2 minutes to establish authority and clarity)
3. MAIN ACTIVITY (self-directed, tied to [CURRENT_TOPIC], with student instructions written directly to students)
4. BACKUP ACTIVITY if the main one finishes early
5. CLASSROOM MANAGEMENT NOTES (seating, bathroom policy, what to do with disruptions — I will fill in specifics, leave brackets)
6. END-OF-DAY REPORT template the sub fills out (what got done, who helped, who struggled)
7. COLLECTION CHECKLIST (what work to collect and where to leave it)

CONSTRAINTS: Assume the sub cannot answer content questions — build an answer key into the plan. Nothing may require materials I have not already got in the room. The tone must be respectful to the substitute.

Variables to fill in

Replace each [variable] in the prompt with your own details:

[SUBJECT] [GRADE_LEVEL] [CURRENT_TOPIC] [NUM_PERIODS]

Example input

SUBJECT=English, GRADE_LEVEL=8th grade, CURRENT_TOPIC=persuasive techniques in advertising, NUM_PERIODS=2

How to use this prompt

Generate this the evening before an absence and print it. Fill in the bracketed management details with your real routines. Keep a generic version in your sub folder for true emergencies.

Tips for the best results

Ask the AI to write student instructions at a 5th-grade reading level so no one can claim confusion.
Request a version where the main activity produces something to grade on return.
Add your seating chart file name in the management notes so the sub finds it fast.
