What to Include in a Lesson Plan for a Substitute Teacher (Full Checklist)
You wake up sick on a Tuesday morning. Your first thought isn't rest — it's the substitute lesson plans. Who's teaching your class? What are they going to do? Did you leave enough detail for someone who doesn't know your students, your routines, or where you keep the scissors?
If you're a teacher, this panic is familiar. And if you're a substitute, you'll know the other side equally well: walking into a classroom to find a sticky note that says "worksheets on the desk — have fun! 😊" and nothing else.
According to substitute teachers on Reddit, the problem is widespread. One sub described receiving plans with long stretches of unstructured time, like "free drawing for thirty minutes, a simple math game for an hour, or me reading them a book for half an hour."
Another shared a common scenario where the teacher didn't leave anything: "Thankfully I had brought some things."
The result? Subs resort to survival mode. As one put it bluntly: "My job is to show up and make sure nobody dies."
That's not good enough — for the sub, your students, or you. A well-built sub plan is the difference between a class that keeps learning and one that descends into chaos. The catch? Most guides tell you what to include but not why it matters specifically for a substitute — someone who doesn't know your kids, your curriculum, or your classroom quirks.
That's exactly what this checklist fixes.
The Anatomy of a Perfect Sub Plan: A 6-Point Checklist
Here are the six essential components every substitute lesson plan needs to be effective.
1. Clear, Timed Activity Blocks (Not Just a To-Do List)
The single biggest failure in most sub plans is a vague to-do list with no timing. "Do math, then reading" tells a substitute nothing useful. How long is math? What happens when they finish early? When does reading start?
Without clear timing, unstructured stretches emerge — and unstructured time is where classroom management breaks down.
Structure your plan in explicit time blocks, like this:
| Time | Activity | Notes |
|---|---|---|
| 9:00 – 9:10 | Bell ringer / morning work | Worksheet already on desks |
| 9:10 – 9:45 | Math lesson | Slides 3–10 on the laptop |
| 9:45 – 10:15 | Independent practice | Worksheet in the blue folder |
| 10:15 – 10:30 | Reading circle | Students choose a partner |
Each block should have a clear start time, end time, and a one-line description of exactly what's happening. This gives the sub a moment-to-moment roadmap and prevents the dreaded "we've got 40 minutes left and nothing to do" situation. MyKelly and The Booksomm both flag timed blocks as one of the most critical structural elements in an effective sub plan.
2. Minimal-Materials Tasks (Because Nobody Knows Where the Glitter Is)
Here's something a sub won't tell you: even if your plan says "use the art supplies in the red cabinet," they probably won't find them in time — or at all. Substitutes don't know your classroom layout, your storage system, or which drawer sticks.
Design your sub activities around what's already visible or needs only the basics, such as:
- Pencil and paper
- A Chromebook
- A pre-printed worksheet
If you want to go the extra mile, set up a "sub tub" — a labelled box or folder left on your desk with everything the sub needs, ready to go.
Good minimal-materials tasks include:
- Pre-printed worksheets (already on desks or in a clearly labelled folder)
- Reading assignments from textbooks students already have
- Discussion or reflection prompts written on the board
- Digital tasks via Google Classroom — the sub just needs to tell students to open it
The fewer moving parts, the smoother the day runs.
3. Explicit Classroom Management Cues (Your "How-To" Guide for Your Classroom)
A substitute walking in cold doesn't know how you get the class's attention, how students signal they need help, or what happens when someone acts out. Without this information, even the most capable sub is flying blind.
Include a short but vital management section covering:
- Your attention signal — e.g., "I clap three times and students echo back" or "I say 'Class, class!' and students respond 'Yes, yes!'"
- Transition procedures — how students move between activities, line up, or submit work
- Behaviour expectations — brief class rules and what the sub should do if a student is disruptive (e.g., "First reminder, then name on board, then send to Room 12 with the pink slip")
- 2–3 trusted students — name a few reliable students the sub can ask for help navigating classroom procedures
As Swing Education advises: "Write your name on the board to establish authority. Clearly explain the day's agenda and expectations right away." Your management cues make that first five minutes possible.
One caveat from the subs themselves: don't micromanage. One sub vented about a plan that included step-by-step hall directions like "when everyone is in line, lead the class down the hall and up the stairs." Keep management notes essential, not exhausting.
The Fastest Way to Build a Substitute-Ready Lesson Plan
Here's the honest problem with everything above: building a sub plan to this standard takes time — time you don't have when you're scrambling at 6 AM with a fever, or covering a last-minute absence for a colleague.
That's exactly where Chalkie comes in. It's an AI-powered lesson plan generator that auto-generates a complete, structured lesson in under 30 seconds — not a bare-bones text document, but a fully formatted, presentation-ready slideshow the sub can walk in and teach from immediately.
Here's what makes Chalkie particularly useful for these situations.
It Builds the Actual Classroom Artifacts
Enter a topic, year group, subject, and curriculum framework. Chalkie produces a slide deck with timed activities, learning objectives, and key vocabulary already structured in. No building from scratch.
It's Curriculum-Aligned in 23+ Regions
Chalkie aligns to standards across countries, including the US (Common Core, NGSS, TEKS), England, and Australia (ACARA). Even if the sub is unfamiliar with your scope and sequence, the content is standards-matched.
It Generates Differentiated Worksheets Instantly
The AI Worksheet Generator produces print-ready worksheets with mixed question types — multiple choice, short answer, fill-in-the-blank. Crucially, it generates differentiated versions in one click: a scaffolded version for students who need support and a stretch version for early finishers. Answer keys included.
It Exports to Common Formats
Export your lesson to Google Slides, PowerPoint, or PDF in one click for instant sharing with your sub.
The result is a complete sub-ready package — slides, worksheet, and differentiated activities — in the time it takes to make a cup of tea. Used by over 1,000,000 teachers across 100+ countries, Chalkie was built specifically so teachers don't have to rebuild the wheel every time they need classroom materials.
Continuing the Checklist: The Finer Details That Make a Difference
With the core activities planned, these final three elements address the crucial details that prevent classroom chaos.
4. Student Rosters and Seating Plans (The Key to Classroom Control)
This one is non-negotiable. A substitute cannot manage a class effectively if they don't know who anyone is. And when behaviour issues arise — which they will — not knowing names makes accountability nearly impossible.
One sub described it perfectly: "I can't figure out their names... or if you can get another teacher to help you figure out who committed any really unacceptable behavior."
Leave the sub with:
- An up-to-date class roster with full names
- A clear, visual seating chart — ideally a simple grid labelled with names
- Brief notes next to relevant students, such as:
- Allergies
- Preferential seating needs
- EBD/SEL considerations
- Students who are pulled out for support services
This removes one of the biggest sources of sub anxiety and gives them the tools to hold students accountable by name from minute one.
5. Meaningful Early Finisher Tasks (That Aren't Just Busywork)
Fast finishers with nothing to do become a disruption source — fast. And "busywork" is a word substitutes despise for good reason. Handing a student a word search and calling it extension work fools no one.
Plan genuinely engaging early finisher activities that don't require supervision or explanation:
- Independent reading from the class Resource Library
- Logic puzzles or brain teasers left in the sub tub
- A journaling prompt written on the board (e.g., "Describe a time you solved a problem creatively")
- A long-term project students can work on, planned with an AI Unit Planner
- A specific approved educational site or app — include the URL or app name so the sub doesn't have to guess
The goal is productive, self-directed work that keeps students occupied and learning without pulling the sub away from the rest of the class.
6. The 'What If?' Contingency Slide (Your Emergency Backup Plan)
Even the best-planned lesson can go sideways. The projector dies. An activity wraps up 20 minutes early. A fire drill cuts the lesson in half. Your contingency slide prepares the sub for exactly these moments so they don't freeze.
Address the most common "what if" scenarios:
- Tech fails: "If the projector or internet isn't working, use the printed version in the red folder on my desk."
- Activity finishes too early: "If you have extra time, use one of the AI classroom activities at the back of this plan."
- Emergency drill: "The evacuation procedure is posted by the door — students know the routine."
- Unruly class: "Contact Ms. Davies next door or call the office at extension 201."
For time fillers, Swing Education recommends a handful of no-prep games every sub should have in their back pocket:
- Silent Ball — a quiet passing game that keeps students calm and focused
- Four Corners — a movement-based decision game that works for most age groups
- Reverse Charades — a team guessing game that's genuinely engaging
Including just two or three of these options in your contingency slide can be the difference between a sub who stays calm and a class that spirals.
Set Your Substitute (and Your Students) Up for Success
A great substitute lesson plan isn't just a courtesy — it's a professional responsibility. When these key elements are in place, your sub walks in prepared, your students stay on track, and learning doesn't stop just because you're not in the room.
Building a comprehensive sub plan from scratch takes time you often don't have, especially when you're unwell. Instead of scrambling, you can generate a fully structured, presentation-ready lesson in under 30 seconds.

Frequently Asked Questions
What is the most important thing to include in a sub plan?
The single most important element is a clearly timed schedule of activities. A vague to-do list creates unstructured time, which is where classroom management issues begin. A schedule with specific time blocks (e.g., 9:00-9:45 Math, 9:45-10:15 Independent Work) provides a clear roadmap for the substitute, keeping the day structured and students engaged.
How do you create a sub plan when you're sick and have no time?
For a last-minute sub plan, focus on the absolute essentials: a timed schedule, pre-printed worksheets, a class roster with a seating chart, and contact information for a helpful colleague. When time is short, prioritize clarity and simplicity. Use minimal-material activities and leverage tools like AI lesson planners that can generate a complete, structured lesson with slides and worksheets in under a minute.
Why is a seating chart so important for a substitute?
A seating chart is crucial because it allows the substitute to learn student names quickly, manage behavior effectively, and take attendance accurately. Without it, a substitute cannot hold students accountable by name, making classroom management significantly more difficult. It also helps them identify students with specific needs (like allergies or preferential seating) noted on the chart.
What are the best activities for a substitute to lead?
The best activities for a sub plan require minimal materials and have clear, simple instructions. Opt for tasks like pre-printed worksheets, independent reading, digital assignments on a familiar platform (like Google Classroom), or discussion prompts written on the board. Avoid activities that require complex setups, hard-to-find supplies, or specialized knowledge of your classroom routines.
What is a 'sub tub' and should I have one?
A 'sub tub' is a pre-prepared box or folder containing all the essential materials a substitute teacher might need for an emergency absence. Yes, creating one is highly recommended. Stock it with generic, high-value emergency lesson plans, copies of your class roster and schedule, important school procedures, and a few engaging activities for early finishers. It's a lifesaver for unexpected absences.
How can AI help create better sub plans?
AI lesson planners like Chalkie can generate a complete, curriculum-aligned, and well-structured lesson plan package in seconds. Instead of writing a plan from scratch while you're sick, the AI builds a presentation-ready slideshow with timed activities, creates differentiated worksheets with answer keys, and aligns the content with your specific curriculum standards. This saves an enormous amount of time while producing a high-quality plan a sub can use immediately.
