Substitute Days
AI Sub Plans Generator
Create complete, self-running substitute plans for any class in minutes — a schedule, activities, and instructions a sub can follow without knowing your subject. Wake up sick and have a real plan ready, not a scramble.
Create sub plans freeBeing sick shouldn’t be harder than going in
Every teacher knows the cruel math of a sick day: it’s often more work to be absent than to drag yourself in. You’re running a fever at 5 a.m., and instead of resting you’re trying to write plans a stranger can run, for a class they don’t know, in a subject they may not teach. The result is usually a movie or a worksheet that wastes the day. The sub plans generator builds a complete, self-running plan in minutes — schedule, activities, and a substitute can actually follow it — so you can close the laptop and go back to bed.
Give the basics
Enter the subject, grade, period length, and the topic or skill you want students to work on while you’re out.
Get the full plan
You get a timed schedule, self-running activities, and clear step-by-step instructions written for someone who doesn’t know your class.
Add your notes and save
Add room-specific notes — seating, tech, the helpful student — then print it. Keep a copy in your emergency folder for any day.
What makes a sub plan actually work
A sub plan fails for predictable reasons: it assumes knowledge the substitute doesn’t have, the activity needs the regular teacher to run it, or the instructions are too vague to follow. A plan that works is built around the opposite principles — and the generator bakes them in.
Self-running activities are everything
The golden rule of sub plans: the work has to run without you. That means independent tasks a student can do solo or in pairs — a reading with questions, a review worksheet, a structured writing assignment, a project work-period — not a lesson that requires expert instruction or live facilitation. A substitute should be a calm presence and a monitor, not a stand-in teacher of your subject. Ask for a sub day and the generator builds activities designed to be completed independently, so the class stays productive whether or not the sub knows a thing about your content.
Write instructions for a total stranger
The instructions can’t assume the sub knows your routines, your students, or your room. A strong plan spells out the obvious: where materials are, how to take attendance, what the bathroom policy is, what to do with finished work, and who to call if something goes wrong. The generated plan gives the substitute a clear, ordered script of the day; you just add the room-specific details only you know. The clearer the plan, the fewer the surprises — for the sub and for you when you return.
Emergency plans vs. planned absences
There are two kinds of sub days. A planned absence — a conference, an appointment — lets you tie the sub work to your current unit so the day moves learning forward. An emergency — you wake up sick — calls for a generic, low-prep plan that reinforces skills without needing the next lesson to be ready. The smartest move is to keep a generated, ready-to-go emergency plan in a folder (digital or a literal folder on your desk) so a sick day means grabbing a plan, not building one at dawn. Generate one all-purpose review day now and your future sick self will thank you.
Keep it on-topic, not a throwaway
A movie or a word search signals to students that the day doesn’t count, and behavior follows that signal. A sub plan built on a real, on-skill activity — review of what you’ve been studying, practice that consolidates, a reading that extends — keeps the day productive and the class settled. You can build the underlying materials with the worksheet generator or a reading passage, and a worked example left behind lets a sub with no subject background still support students who get stuck.
Review before you file it
Read the generated plan before you rely on it. Confirm the activities truly run without expert help, the timing fits your period, and nothing assumes a resource your room doesn’t have. A few minutes now — while you’re well — turns a generated draft into a plan you can drop in place on your worst morning with total confidence.

Sub plans, answered
Is the sub plans generator free?
Yes — create substitute plans free with Education Copilot. It’s part of the same toolkit as the lesson planner, worksheet and reading tools, so you can build the plan and the materials it needs in one place.
What’s included in a generated sub plan?
A timed schedule for the period, self-running activities students can do independently, and step-by-step instructions for the substitute. You add room-specific notes like seating, tech access and emergency contacts.
Can I make an emergency plan to keep on file?
Absolutely — that’s the smartest use. Generate a generic, skill-reinforcing day now and keep it in your emergency folder so a sick morning just means grabbing the plan instead of writing one while ill.
Will the activities run without the sub knowing my subject?
That’s the design goal — the activities are built to be student-driven and independent, so the substitute supervises and supports rather than teaches. Add a worked example or answer key and a sub with no subject background can still help students who get stuck.
Be ready for the day you can’t come in
