Using AI to Create Better Substitute Lesson Plans

One of the most practical ways teachers can use AI is to help create strong substitute lesson plans. We all know how frustrating it can be to write sub plans, especially when we are already sick, attending a meeting, or trying to prepare for being out of the building.

The problem is that many teachers open an AI tool and type something like, “Make me a sub plan for tomorrow.” The result is usually too generic because the AI does not know our room, our schedule, our procedures, our students, or the way our school day works.

The key is to give AI the information it needs in a way that can be reused.

I recommend thinking about substitute lesson plan prompts in two parts:

1. Reusable classroom information
2. Daily lesson information

The reusable information is the material that stays mostly the same every time we are out. This includes things like room number, phone extension, bell schedule, lunch period, off periods, safety procedures, attendance expectations, classroom rules, technology expectations, and where students submit work.

The daily information is the part that changes each time. This includes the date, the lesson topic, the assignment, the learning objective, links students need, what students should turn in, and what the substitute should do if students finish early or technology does not work.

By separating those two pieces, we can make the process much faster. Once the reusable information is saved, we only need to add the daily lesson details each time.

Step 1: Create a Reusable Classroom Profile

The first thing I would have teachers do is create a classroom profile. This is a block of information they can save and reuse every time they need a substitute plan.

Here is the kind of information I would include:

My Classroom Profile:

Teacher Name:
Room Number:
School Name:
Subject(s) Taught:
Grade Level(s):
Phone Extension:
Email:
Neighboring Teachers Who Can Help:
Main Office Contact:
Emergency/Safety Procedures:
Evacuation Route:
Lockdown Procedure:
Attendance Procedure:
Bathroom/Hall Pass Procedure:
Technology Expectations:
Cell Phone Policy:
Classroom Rules:
Behavior Management Notes:
Where Materials Are Located:
Where Students Turn In Work:
Lunch Period:
Planning Period/Off Period:
Bell Schedule:
Special Notes for Substitutes:

This information could be saved in a Google Doc, Word document, Notes app, or another place that is easy to copy and paste. If the AI tool has a memory or custom instructions feature, some of this standard classroom information could also be saved there, as long as it does not include private or sensitive student information.

Teachers should not put confidential student information into an AI tool. That means avoiding details about IEPs, medical issues, discipline history, family situations, or anything else that would be considered private student data.

Step 2: Add the Daily Lesson Information

After the reusable classroom profile is created, the teacher only needs to add the information that changes for that specific absence.

That might look like this:

Date of Absence:
Classes Meeting That Day:
Unit or Topic:
Learning Objective:
What Students Already Know:
Assignment or Activity:
Materials Needed:
Links Students Need:
Canvas/LMS Directions:
Expected Student Product:
What the Substitute Should Say:
What the Substitute Should Do During Class:
What Students Should Do If They Finish Early:
What to Do If Technology Fails:
How Work Should Be Submitted:
Any Assessment or Grading Notes:

This is where the teacher provides the actual instructional content. AI can organize and format the plan, but the teacher still needs to provide the classroom context and the academic purpose of the lesson.

Step 3: Use a Strong Prompt

Once the teacher has the reusable classroom information and the daily lesson information, they can use a prompt like this:

You are helping me create a clear, professional substitute teacher lesson plan.

Use the classroom profile and daily lesson information below to create a substitute plan that is easy for a substitute teacher to follow without needing additional explanation.

The plan should include:

1. Teacher and classroom information
2. Bell schedule and class periods
3. Attendance instructions
4. Safety and emergency procedures
5. Classroom expectations
6. Technology expectations
7. Step-by-step instructions for each class period
8. What the substitute should say to students
9. What students should be working on
10. What to do if students finish early
11. What to do if technology does not work
12. Behavior management guidance
13. Where students submit work
14. Notes for the substitute to leave for me at the end of the day

Write the plan in a format that is organized, direct, and easy to scan. Use headings, bullet points, and numbered steps. Do not make assumptions. If something is missing, create a clearly labeled placeholder for me to fill in.

Here is my reusable classroom profile:

Here is the daily lesson information:

Create the final substitute lesson plan.

A More Advanced Version

For teachers who want an even stronger result, I would recommend a more detailed version like this:

Act as an experienced teacher creating a substitute lesson plan for a secondary classroom.

Your goal is to produce a plan that allows a substitute teacher to manage the class confidently, keep students productive, and avoid confusion.

Use the information I provide below. Organize the plan so the substitute can quickly find what they need during the day.

Requirements:
- Make the plan practical, not overly wordy.
- Use clear headings.
- Include a “Start of Day” section.
- Include a section for each class period.
- Include exact student-facing directions the substitute can read aloud.
- Include classroom management reminders.
- Include emergency and safety information.
- Include a technology backup plan.
- Include an end-of-day note section for the substitute to complete.
- Flag any missing information with this label: [NEEDS TEACHER INPUT].
- Do not invent school policies or student-specific details.

Why This Works

The reason this approach works is that it gives AI the structure and context it needs. AI is very good at organizing information, creating clean formatting, turning rough notes into professional directions, and identifying missing details.

But AI is not in our classroom. It does not automatically know our students, school policies, bell schedules, safety procedures, or classroom routines. That is why the teacher still has to provide the important information.

A weak prompt says:

Make me a sub plan for tomorrow.

A strong prompt says:

Use my classroom profile, schedule, safety procedures, behavior expectations, and lesson objective to create a step-by-step plan a substitute can follow without asking me questions.

That difference matters.

The Workflow I Would Recommend

I would encourage teachers to follow this process:

First, create a reusable classroom profile. This only needs to be done once and then updated when something changes.

Second, save that profile somewhere easy to access.

Third, when a substitute plan is needed, add the daily lesson information.

Fourth, ask AI to create the final plan using a clear prompt.

Fifth, review the plan carefully. The teacher should check links, times, procedures, student directions, and any school-specific expectations.

Finally, the teacher can print the plan, email it, upload it to the LMS, or leave it in the classroom for the substitute.

Final Point

The goal is not to have AI replace the teacher’s professional judgment. The goal is to have AI take the information the teacher already knows and turn it into a plan that is clearer, more organized, and easier for a substitute to follow.

The best substitute plans are specific enough to prevent confusion, simple enough to follow during a busy school day, and complete enough that the substitute does not have to guess what to do next.

Example:

Act as an experienced teacher creating a clear, professional substitute lesson plan.

Create a substitute plan that is easy to follow, organized by period, and written so the substitute can manage the classroom without needing extra explanation. Use headings, bullet points, and step-by-step directions. Include student-facing directions the substitute can read aloud. Do not invent missing information. If something important is missing, mark it as [NEEDS TEACHER INPUT].
