How to Write Substitute Teacher Lesson Plans That Actually Work

Substitute teacher lesson plans are one of those things every teacher knows they should do well and almost no one does. Most sub plans fall into one of two failure modes: too vague ("have students continue their projects — they'll know what to do") or too dependent on things only you know ("use the routine we established in September").

A good sub plan should allow a competent adult who doesn't know your students, your classroom, or your curriculum to run a productive class period. That's a different design challenge than writing a lesson plan for yourself.

What Makes Sub Plans Fail

No classroom management information. The sub doesn't know your routines, your signals, your seating chart, or which students need what. If you don't provide this, the sub has to wing it.

Activities that require prior knowledge the sub doesn't have. "Continue analyzing the primary sources from the Reconstruction unit" assumes knowledge the sub doesn't have. "Read the attached article and answer the discussion questions on the next page" is self-contained.

Work students won't take seriously. Students know sub-day busywork when they see it. If the assignment is clearly a placeholder that won't be used, expect proportionally low effort.

Nothing for early finishers. Students who finish in 15 minutes with 30 minutes left and no guidance will fill that time themselves.

Unclear expectations for what should be collected/submitted. Does the sub collect work? Does the work get graded? Students who don't know won't take it seriously.

The Self-Contained Sub Plan

A sub plan that works is self-contained — everything the sub needs is in the packet. This includes:

Class schedule with times. When does class start? How long is the period? Is there a break? When does it end?

Student roster and seating chart. Ideally labeled with photos if your school allows it. At minimum, a seating arrangement so the sub can call on students by name and take attendance accurately.

Attendance procedure. Exactly how does attendance work at your school? What does the sub do with it?

Classroom routines. How do students enter? Where do they put belongings? What's the procedure for bathroom passes? What's the signal for getting students' attention? What are your class norms?

Emergency procedures. Where is the fire exit? What's the lockdown procedure? Who does the sub contact if there's a problem?

Specific student notes. Without violating confidentiality: "Student A may need to leave briefly for medication at 10am — escort to the nurse's office." "Student B sometimes struggles with transitions — a quiet reminder helps." These notes make the difference between a sub who feels supported and one who feels set up to fail.

Designing Sub Activities

The best sub activities share several characteristics:

Self-explanatory. Students can read the directions and begin without the sub needing to explain the content. Numbered steps, simple language, clear product.

Tied to current curriculum. "Read this article about the topic we've been studying" keeps students engaged with real learning, not busy work. The activity should feel like a legitimate part of the class, not a placeholder.

Appropriate for independent work. Partner or small group activities can work, but require more management skill from the sub. When in doubt, design for individual work.

Defined product with collection. Students complete something specific (written response, problems solved, annotation) that is collected at the end. This signals that the work matters.

Built-in accountability. "This will be checked for completion and may be discussed when the teacher returns" produces more effort than "this is just for practice."

A Go-To Sub Plan Template

Keep a generic, adaptable sub plan template you can update quickly:

Opening (5 min): Sub introduces themselves, reviews the task for the day.

Work time (25-30 min): [Insert self-contained activity — see file attached] Students work individually. Sub circulates and assists.

Early finisher option: [Always have one] "If you complete the assignment before time is called, use the remaining time to: read your independent reading book / complete any missing work / work on vocabulary practice from the board."

Closure (5 min): Sub collects all work in the labeled box on the teacher's desk.

The bracket items are what you customize. Everything else is boilerplate that works for any day.

Sub Plans for Different Situations

Planned absence (scheduled appointment, conference, PD day): You have time to prepare. Write the full self-contained plan with the actual curriculum. Leave related materials with clear organization.

Unplanned absence (illness): You're writing at 5am with a fever. Have emergency sub plans ready in advance — a generic but substantive activity that works with minimal current-unit context. Store these digitally so you can email them from home.

Digital sub plans: Store your sub plan template and any emergency plans on a shared drive with your department chair or designated colleague who can print and leave them out if you can't call in early enough.

Preparing Students for Sub Days

The quality of a sub day depends heavily on student norms. If your students are used to clear expectations and understand that sub days are part of the class, not days off, they'll behave accordingly.

Explicitly teach your students: "On days when I'm absent, a sub will run class. Everything about class is the same — you're here to learn, you're expected to follow the same norms, and the work you do that day counts."

Following up after a sub day — reviewing the work submitted, discussing any issues, writing a brief thank-you note to a sub who handled things well — reinforces that sub days are not a consequence-free zone.

A good sub plan protects your class's learning. It also protects your relationship with your subs — the ones who had a good experience in your room will come back.
