You’re sick. It’s 6 AM. You need sub plans in your inbox before the substitute arrives at 7:30. AI generates complete, print-ready sub plans in 10 minutes — including lesson activities, classroom procedures, and student notes.

The emergency sub plan prompt

``` Create a complete substitute teacher plan for [grade level] [subject].

Date: [date] Class periods: [schedule with times] Number of students: [number]

For each period, provide:

• Learning objective (aligned to what we’re currently studying: [topic])
• Activity (self-contained, requires no special materials)
• Materials needed (only what’s in the classroom)
• Step-by-step instructions the sub can follow
• Early finisher activity
• Estimated timing

Also include:

• Classroom procedures (bathroom, water, dismissal)
• Behavior expectations and consequences
• Students who may need extra support: [list without details]
• Emergency contacts: [office number, neighbor teacher]
• Seating chart location: [where to find it]

Format as a clean, printable document with clear headings. ```

Grade-specific examples

Elementary (K-2)

``` Grade 1, full day Morning: Reading — students read independently from book bins (20 min), then partner read (15 min), then draw favorite scene (15 min) Math: worksheet in the blue folder on my desk (already copied) Afternoon: Science — watch BrainPOP Jr video on [topic] (login on sticky note on computer), then draw and label diagram Specials: Art at 1:15 (Ms. Johnson, Room 204) ```

Middle school (6-8)

``` 8th Grade English, 4 periods All periods same lesson:

1. Silent reading (15 min) — books in desk or classroom library
2. Vocabulary worksheet (20 min) — copies in sub folder
3. Journal prompt: “Describe a time you had to make a difficult decision” (15 min)
4. Share with partner (5 min) Early finishers: Read independently or work on any missing assignments ```

High school (9-12)

``` AP US History, 3 periods All periods: Document-Based Question practice

1. Distribute DBQ packet (copies in sub folder, top shelf)
2. Students read documents independently (20 min)
3. Students outline their response (20 min)
4. Peer review outlines in pairs (10 min) No homework assigned. Collect all work at end of period. ```

The “sub plan bank” strategy

Don’t wait until you’re sick. Build a bank of emergency plans at the start of the year:

``` Prompt: “Create 5 emergency sub plans for [grade/subject] that:

• Are self-contained (no prior knowledge needed)
• Require only basic classroom materials
• Cover a full [period length]
• Are engaging enough that students stay on task
• Align generally with [curriculum area]

Make each plan different: 1 reading-based, 1 writing-based, 1 collaborative, 1 video + activity, 1 review game. Label each clearly so I can grab one quickly.” ```

Print these and keep them in a “Sub Folder” on your desk. When you’re sick, just text your sub: “Use Plan #3 from the blue folder.”

Classroom management notes

The part subs need most:

``` Prompt: “Write a classroom management guide for a substitute teacher.

Grade: [level] General behavior: [well-behaved / needs structure / challenging class] Reward system: [describe if any] Consequence system: [describe steps] Students who need extra attention: [first names only, brief notes] Reliable student helpers: [names] Neighboring teacher for help: [name, room]

Keep it to one page. Use bullet points. The sub should be able to read this in 2 minutes.” ```
