It’s 5:40 a.m. Your throat feels like gravel, the room is spinning a little, and you already know how today is going to go. You’re not going in. And then the second thought hits — the one that’s almost worse than being sick: I have to write a sub plan.
Let’s just say the quiet part out loud. The worst part of being sick as a teacher isn’t the fever. It’s building a full day of instruction from the couch, with a headache, for a stranger who’s never met your kids. So most of us do the thing we swore we’d never do: drag ourselves in sick, because it feels easier than the alternative.
It shouldn’t be that way. A good sub day should already be done — sitting in a folder — long before you ever need it. Here’s what that actually looks like.
What a sub day actually needs (so a stranger can run it)
The mistake most sub plans make is assuming the substitute can teach your content. They can’t — and they shouldn’t have to. A sub day that truly holds a room together checks four boxes:
- No technology. Wi-Fi goes down, logins fail, the cart is missing. A real sub day works on paper.
- No textbook. If it depends on a book half the class left in their lockers, it falls apart.
- No prep. Future-you should be able to print it (or drop the PDF in the sub folder) in under five minutes.
- No special knowledge from the sub. A substitute with zero ELA background should be able to walk in cold and run a calm, productive period.
That last one is the one everybody forgets. Which brings us to the single most important page in any sub folder.
The “Dear Substitute” letter that does the teaching for you
The secret to a sub day that runs itself is a minute-by-minute letter to the substitute — not a vague “have them read Chapter 4,” but an actual script: First 5 minutes, hand out the packet. Minutes 5–20, silent reading. Minutes 20–45, questions and the written response. Last 5–10, collect on my desk.
When the sub knows exactly what to do and say, the room stays calm. When they’re guessing, it doesn’t. That one page is the difference between coming back to a settled classroom and coming back to chaos.
Build your sub folder once — use it for years
Here’s the move that actually buys back your peace of mind: build the folder before you need it, while you’re well. Print a few complete, self-contained ELA days. Add one “Dear Substitute” letter per day. Drop in a class-info sheet (bell schedule, the reliable teacher next door, where the passes are). Then forget about it until the morning you wake up sick — and discover it’s already handled.
Grab a free sub day right now
If your folder is empty, start here. I made a free, no-prep ELA sub day — a short suspense story called “The Long Way Down,” with comprehension questions, a written response, an early-finisher extension, a “Dear Substitute” letter, and an answer key. Print it, drop it in your folder, and you’re covered for one day. Get the free sub day here.
Or cover the whole week in one move
One free day is a great start. But you don’t get to choose when you go down — so it helps to be covered no matter what. Wake Up Sick & Already Covered is five complete, no-prep ELA days across five genres — narrative, science, biography, paired texts, and argument — each with its own “Dear Substitute” letter and answer key. About 56 pages. Print once, reuse every year. It’s $7, and it’s the cheapest insurance policy a teacher can buy.
Take the sick day. You’ve earned it. Let the folder do the work.
