Middle School Sub Plans: How to Plan for Every Period

Middle school sub plans have one major advantage over elementary plans: you usually do not have to plan the entire school day for one group of students.

They also have one major problem: you may have to survive the same lesson six times.

One class may take the full period. Another may finish twenty minutes early. One section may work quietly. Another may decide that a substitute means all classroom expectations have been suspended until further notice.

Your plan has to work across that variation.

Write for the substitute who does not teach your subject

This is the safest assumption.

If you teach science, do not assume the substitute can explain density. If you teach math, do not assume they are comfortable teaching your current method. If you teach ELA, do not assume they have read the novel.

That does not mean students cannot do academic work. It means the task should contain enough information for students to work without the substitute becoming the content expert.

Review, structured reading, guided practice, short source analysis, vocabulary in context, retrieval practice, independent writing, or previously taught problems usually travel better than a brand-new difficult concept.

Put the bell schedule at the top

Include the start and end time for every period.

If the day uses blocks, odd/even periods, shortened classes, advisory, homeroom, or an assembly schedule, make that obvious.

Mark your planning period too. The substitute should not have to wonder whether an empty period means they missed a class.

Give each period a clean stopping point

If every class is doing the same lesson, tell the substitute where to stop.

For example:

Students should complete questions 1 through 12. If time remains, they begin the extension on the back. Do not start tomorrow’s section.

That helps prevent one class from racing ahead while another gets stuck halfway through.

Leave more work than the fastest class needs

This is one of the most common middle school sub-plan failures.

A worksheet you expect to take forty-five minutes takes one class twenty-two minutes. Now the substitute has twenty-three minutes of eighth graders and no plan.

I taught middle school science before moving into elementary classrooms, and I would always rather leave a clear backup task than expect a substitute to stretch an assignment that is already finished.

Label the backup clearly. It can be independent reading, review questions, missing work, an extension problem, a short writing response, or another familiar assignment.

Tell the substitute how students get the assignment

If the work is online, include the exact location.

“It’s on Canvas” may be enough for your students, but it is not enough if the substitute has no idea what students should see.

Write something like: “Students open Canvas, choose today’s module, and complete ‘Energy Review 2.’ The assignment is already published.”

Then leave an offline fallback in case devices, Wi-Fi, or logins fail.

Keep student directions short

Middle schoolers are very good at finding ambiguity.

If the direction says “work with a partner if needed,” somebody will eventually explain that this means six people should move their desks together.

Be specific about whether work is independent, partner, or group. Say whether headphones are allowed. Say whether students may move seats. Say what gets turned in.

The Direction Clarity Checker can help tighten long directions, and the effective directions guide explains how to make steps easier to follow.

Use the seating chart

A substitute cannot enforce much of anything if they do not know who anyone is.

A readable seating chart gives them names, locations, and at least a fighting chance when a student insists, “She always lets me sit over there.”

If yours is outdated or hard to read, use the Seating Chart Maker.

Explain the behavior system without writing a threat letter

Tell the substitute the normal expectation and the next step if a student ignores it.

For example: one reminder, seat change, then contact the office according to school procedure.

Use whatever your actual school process is. Do not invent harsher rules for substitute days unless your school requires them.

If a particular class is already difficult for you, it is unrealistic to expect a stranger to fix the class for a day. Make the work straightforward, reduce unnecessary movement, use assigned seats, and give the substitute a clear route for help.

The Classroom Behavior Troubleshooter may help with recurring issues before the next absence.

Leave a period log

This is a simple addition that can save you a lot of confusion when you return.

Give the substitute a small table or space to note:

Where the class stopped
Whether most students completed the work
Any major issue you need to know about

You do not need a written review of every child.

Block periods need a different plan

If classes are eighty or ninety minutes, one independent worksheet is usually not enough.

Build two or three chunks: a short opening task, the main assignment, and a second review or extension.

Changing the type of work halfway through the block also helps. Students can read and respond, then switch to practice, discussion with a clear structure, or another familiar activity.

What about high school?

Most of the same rules apply.

High school students may be more independent, but that does not mean a vague “work on your assignment” plan will fill the period. Give a clear product, deadline, and backup task. Be explicit about device use, collaboration, and what gets submitted.

If a course is advanced or highly specialized, avoid making the substitute responsible for teaching content they may not know.

A simple middle school sub-plan structure

First 5 minutes: Attendance and opening task.
Next 5 minutes: Explain the assignment and expectations.
Main work: Independent or structured partner work using familiar material.
Check: Students submit or show the required product.
Backup: Clearly labeled extension or review if time remains.
Last 3 to 5 minutes: Cleanup, return materials, and normal dismissal routine.

Make the plan boring in the best possible way

A substitute day is not the day your classroom has to prove how innovative it is.

Clear, familiar, sufficiently long, and easy to run beats elaborate.
