Students make up their minds about a sub very quickly. They notice whether the room looks ready, whether the adult at the front seems to know what happens next, and whether that adult is calm. You can't bring years of experience into a room you have never seen. You can bring a prepared opening, and that is most of what students are checking.
This lesson covers the half hour before the bell and the first five minutes after it. The opening has the same parts every time, in the same order: the office, the room, the board, the door, the introduction, attendance, and the plan said out loud. Do them in that order every morning and they become automatic, which frees your attention for the class.
At the office
Go to the front office first, even if you know the way to the room. Sign in, show your ID, and pick up whatever the school gives subs: a badge, a key, a folder. Then ask the questions you wrote down the night before. Keep it short and friendly. Office staff are busy at this hour, and a sub who asks a few clear questions is a sub they are glad to see.
Try: "Hi, I'm subbing for Ms. Rivera in room 14 today. Could I ask two quick things? How do I call you from the room, and how is attendance sent?"
Learn the name of the person who helped you and thank them by name. The office is often the place that decides whether a sub comes back, and it remembers who was easy to work with.
In the room, before the bell
Unlock the room, turn on the lights and look around before you sit down. You are looking for a short list of things, and the order matters, because the first few are about safety.
- The drill map by the door, and the route your class takes out of the building.
- The emergency folder, if there is one, with the class list for drills.
- The classroom phone or call button, and how to reach the office in one step.
- The plans: on the desk, in a folder marked Sub, in the teacher's planner or on the screen.
- The seating charts and the class list.
- Any health notes the teacher left, which you read and then keep private.
Then read the whole plan once, start to finish, without acting on any of it yet. Mark the times, any duties and anything you don't understand. After that, read the first hour of the plan twice and just skim the rest. You only need to know the opening well. You can read the afternoon while students work in the morning.
If there is time, introduce yourself to the teacher next door. Ask one question: what should I know about this class? A neighbor who knows your face is far more likely to help when you knock later. If the room has an aide or a co-teacher, they often know the routines better than anyone. Ask them first.
Finally, set out the first sheets or materials so students can start as soon as they sit. Empty minutes at the start of the day are when a class tests a new adult. Work waiting on desks fills those minutes for you.
Your name on the board
Write your name in large, clear letters at the top of the board, with the title you want students to use. Under it, write the date, the day's schedule with times, and a first task students can start without asking.
- Your name, as you would like to be called.
- The date, which the teacher will want on the work.
- The schedule: each block with its time, including specials and lunch.
- The first task, in one line, such as "Read your book quietly" or "Start the sheet on your desk."
The board answers the three questions students ask any new adult: who are you, what are we doing, and when is lunch. Every question the board answers is one you don't have to answer twenty times. Leave space to cross off each part of the schedule as you finish it. That small habit shows progress and keeps the class oriented all day.
If the room has a projector, you can put the morning on the screen with a timer for the first task. Keep a written copy on the whiteboard too, in case the screen gives you trouble.
At the door
When students arrive, stand at the door. Say good morning, smile, and point them to the board. You don't need to say much. "Good morning, the first task is on the board" is plenty.
Standing at the door does several jobs at once. Students meet a person before they meet the room. You get a look at each student, which helps with names and with noticing who seems tired or upset. And a class walks in more calmly past an adult in the doorway than into an empty room.
In the younger grades, students may line up outside and walk in together. Stand at the front of the line, greet them and walk them in. In middle school, students arrive in a stream between periods, so stand in the doorway where you can see both the hall and the room.
Don't sort papers or read the plan while students come in. The minutes at the door are the cheapest classroom management you will do all day.
One sentence about you
Once everyone is in and seated, wait quietly at the front until the room settles. Then introduce yourself: your name, why you are here, and one friendly sentence about yourself.
Try: "Good morning. My name is Mr. Okafor, and I'm your teacher today while your teacher is away. I grew up near the ocean, and I still love anything about sea animals."
One sentence is enough. It makes you a person without opening a long conversation. Students may ask follow-up questions. Answer one, briefly, and say there will be time later. Keep personal details to yourself, such as where you live or your family, and never share your phone number or social media with students.
Next, say what you expect, in one line, and tie it to the teacher the class already knows.
Try: "Everything today works the way it does with your teacher. Same rules, same routines."
That one line connects you to an authority students already accept. You aren't starting a new set of rules from scratch. You are keeping theirs going.
Find out the class's signal
Before you go further, ask the class how their teacher gets them quiet. Have one student show it, and have the class answer it once, right then. Now you know the signal, and the class has already followed you once on something they know. Lesson 3 is all about signals. For the first five minutes, you only need to ask, practice once and use it.
Attendance from the seating chart
Take attendance while students start the first task, not before it. Calling names to a waiting class invites silly answers and wastes minutes. Use the seating chart and look instead.
- Find the seating chart in the plans or on the desk.
- With students working, walk the room or scan from the front, checking each seat.
- Mark empty seats as absent.
- Quietly check any seat you are unsure about: "Can you tell me your first name?"
- Send attendance the way the office asked, by the time they asked.
Students sometimes switch seats on a sub day as a joke. You don't need to make it a contest. Say calmly, "Please sit where the chart says, so I can learn your names," and wait until they do. Then carry on.
Keep the seating chart in your hand or on a clipboard all morning, and use names whenever you can. A student called by name is far easier to redirect than "you in the blue shirt." If there is no seating chart, have students write their first names on a folded card on their desks. It takes one minute and helps all day.
The plan, out loud
Once attendance is sent, say the day's plan out loud, pointing to the board as you go. Keep it to a quick walk through the blocks, not a list of instructions for every part.
Try: "Here's our day. First we'll finish this reading sheet. Then math, then specials at 10:15. After lunch, writing and a read-aloud. I'll cross things off as we go, so you always know what's next."
Saying the plan does two things. It tells students the day is organized and predictable, which settles anyone uneasy about a missing teacher. And it gives you a promise you can point back to later: "Remember, after this sheet it's math."
Then give the instructions for the first full activity, clearly and once. Write the key step on the board. Ask one student to say back what to do, then start. Keep each instruction to the next step, not the whole morning. Say what finished work looks like, where it goes and what early finishers do. From here you are running the day, and the hardest part is behind you.
If you have a duty first
Some jobs start with a duty before class: the bus line, the cafeteria or the playground. Ask the office where to stand and who else is on duty, and introduce yourself to that adult. Before you leave the room, write the board and set out the first task, so students have something to do when they come in. Ask the office who opens the room and who greets the class if you aren't back in time. Then come back as quickly as the duty allows and start the opening from wherever the class is.
If the duty ends with walking a group of students to class, count them at the start and at the door. A group you walk is a group you are responsible for, the whole way.
When the opening goes sideways
Not every morning goes to plan. Each of the common problems has a simple answer, and none of them means starting over.
Students arrive before you're ready
Greet them anyway, and give them something to do right away: "Please read your own book quietly while I get set up." Then finish the board while they read. A calm adult doing a quick task is fine. A rushed adult searching drawers is what unsettles a class.
The class comes in loud
Don't talk over it. Stand at the front, give a signal or simply wait, and look calm. When it is quieter, say good morning in a low voice. Starting softly pulls the room down to your level instead of pushing you up to theirs.
A question you can't answer
Students will ask about a field trip, a test or a class reward you know nothing about. Say honestly that you'll check, write it down, and put it in the note for the teacher. "I don't know, but I'll make sure your teacher sees your question" is a good answer.
A student is upset
Some students find a missing teacher hard, especially younger ones. A quiet word, a reminder that their teacher will be back, and a small job like handing out papers often helps. If a student stays upset, ask the office or the teacher next door, and mention it in your note as an event: when it happened and what you did.
In middle school, every period
If you are covering a middle school schedule, you will repeat a short version of this opening at the start of every period. Your name stays on the board. Say a quick hello at the door, use the signal, take attendance from that period's chart, and give the plan for the period in two sentences. It gets faster each time. By the third period it will feel like routine.
Whatever goes wrong, the order stays the same: the board, the door, the introduction, attendance, the plan. Go back to the next step and carry on.
