Lesson Plans for Substitute Teachers: What to Leave, What to Avoid

Writing substitute teacher plans is one of those tasks teachers dread disproportionately to how often they have to do it. The dread is legitimate: poorly written sub plans lead to wasted class time, management problems, and a mess to clean up when you return.

Good sub plans are a specific genre. They're not your normal lesson plans. They're designed for someone who doesn't know your students, doesn't know your content, and may be walking in with thirty seconds of preparation.

What a Sub Actually Needs

Substitute teachers need exactly four things:

1. Attendance and seating — where to sit students and how to take attendance
2. The schedule — what happens when, including any non-instructional duties (hallway supervision, dismissal procedures)
3. Student work — specific, self-contained tasks that students can complete without explanation from an unfamiliar teacher
4. Management basics — what to do when students need to go to the bathroom, who to call if there's a problem, where the office referral forms are

Everything else is noise. A sub plan that includes your instructional philosophy, a list of students' learning goals, and detailed notes on your gradebook philosophy will not be read. Keep it short and specific.

The Self-Contained Task Principle

The most important principle in sub plan design: the task should be self-contained. Students should be able to start and complete the work without any content explanation from the substitute.

This is the failure point of most sub plans. Teachers leave plans that include activities the substitute is expected to introduce, explain, or lead discussion around. Substitutes who don't know the content can't do this effectively. The lesson stalls, students disengage, and everyone has a bad day.

Self-contained tasks:

• Independent reading with response questions
• Writing prompts with clear rubrics or exemplars to reference
• Practice sets with answer keys students can self-check at the end
• Video with a note-taking guide
• Review activities with directions fully written in the materials

Non-self-contained tasks:

• Anything requiring the sub to "explain" or "introduce"
• Class discussion without explicit prompts and protocols
• Lab work without a fully written procedure
• Any activity that requires teacher content expertise

What to Actually Assign

The most reliable sub day activities are:

Silent reading with structured response. Reading in any format — independent book, article, textbook chapter — with specific written response questions that require evidence from the text. Students work independently. The sub circulates. No content knowledge required.

Practice with answer key. Math practice, vocabulary review, grammar exercises — any activity where correct answers can be provided to students (or revealed at the end for self-checking) so the sub doesn't need to evaluate work in the moment.

Timed writing. A specific prompt with a clear time frame. Students write. The sub doesn't evaluate anything — they just collect papers at the end. Works for any grade, any subject.

Educational video with guided notes. A video you've pre-selected, with a notes sheet students fill in while watching. Requires a projector and working speakers, which you should verify are available. Build in a reflection prompt at the end.

Review packet. A packet covering recently taught material with self-contained directions. Students work at their own pace. No new content is introduced.

How to Write Student Directions

Student directions in sub plans need to be more explicit than directions you'd normally give. Your normal directions rely on students knowing your routines and expectations. Sub day directions assume nothing.

Write them in steps:

1. Take a piece of notebook paper.
2. Write your name, today's date, and the period number.
3. Read pages 47-52 in your textbook.
4. Answer questions 1-5 on the attached sheet in complete sentences.
5. When finished, turn your paper face-down and work on something else quietly.

Numbered steps eliminate ambiguity. Students who "finish early" need to know explicitly what to do next — otherwise they create management problems for the sub.

Management Information for the Sub

Keep this section brief and practical:

• Bathroom policy: two students out at a time, sign the log on the desk
• If a student is disruptive: send to room [X] with a referral note (attached)
• Emergency procedures: posted by the door
• Who to call with questions: room [X] or the office at ext. [X]

Include a class roster with any essential information the sub needs to know. Allergies, if applicable. Students with IEP accommodations the sub should honor. Any student who might have a particularly hard time with a substitute.

Don't include details that aren't actionable in the moment. The sub doesn't need to know why a student struggles — just what to do when they do.

Building a Sub Plan Template

Teachers who create absences are often sick, and sick teachers don't write great sub plans. Build a reusable template before you need it.

The template should have blank spaces for the date-specific tasks and pre-filled sections for everything that stays the same: schedule, seating chart, bathroom policy, management contacts. When you're too sick to write a detailed plan, you fill in the task section and everything else is already there.

Keep the template in the same folder as your gradebook or in a binder in your classroom. The best sub plan is one that exists and is accessible — not one that's perfectly written but on a computer you can't log into from home.
