25 sub-day activities a substitute can run with no prep

Grades K–825 ideasUpdated October 2026

The best sub-day activities need nothing from you on the morning you're out: a page the substitute opens on the projector, a sheet already in the emergency folder, or a game with rules that fit on a card. These twenty-five cover the whole day, from the opener to the exit ticket, and each says what the substitute does, what to leave and the grades it suits.

Openers

  1. 1. The board on the projector

    The substitute opens the morning board, types the day's plan into it and leaves it on the projector, so students see the schedule and the clock all day.

    Grades K–8You need The morning boardUse Morning board

  2. 2. Would you rather warm-up

    The substitute spins the would-you-rather wheel and students move to one side of the room or write their choice and one reason. It breaks the ice with a new adult.

  3. 3. Journal prompt

    The substitute picks a prompt for your grade and students write for ten minutes in their journals. Leave a note saying where the journals are kept.

  4. 4. Two truths and a lie about the sub

    The substitute tells three facts about themselves, one false, and students vote on which is the lie. Then students may ask the sub one question each.

Reading and writing

    The substitute shows a read-aloud on the projector, reads it to the class, and asks the discussion questions printed with the story.

  3. 7. Story map for the read-aloud

    After the read-aloud, students fill in a story map: characters, setting, problem, events and solution.

  4. 8. Word search with this week's words

    Make a word search from your current word list once and keep copies in the emergency folder. Students find the words, then write sentences with three of them.

  5. 9. Silent reading with a log

    Students read their own books for twenty minutes and fill in their reading log. The substitute reads too, which keeps the room quiet.

    Students write you a short letter about the day: what they did, what they learned and one question for you. You get a report in their words.

    Grades K–5You need A number written on the board

  5. 16. Practice sheet by topic

    Leave a class set of a math sheet on a topic the class already knows well, so the substitute doesn't need to teach anything new.

    Grades 1–8You need Printed practice sheetsUse Math worksheets by topic and grade

Games and breaks

    The substitute draws a brain break card when the class gets restless and leads it from the front. Every card says what to do.

    Grades K–5You need The brain break cardsUse Brain break cards

    Students sit on their desks and toss a soft ball in silence. A dropped ball or a sound means sitting down for the next round, and everyone is back in for each new round.

  3. 19. Category game

    Spin a letter. Students list a food, an animal, a place and a name starting with that letter in two minutes. Unique answers score a point.

  4. 20. Twenty questions

    The substitute thinks of an animal or object and the class asks up to twenty yes-or-no questions to guess it. A student who guesses right leads the next round.

  5. 21. Heads up, seven up

Making it work

  • Build an emergency sub folder in August with a week's worth of these, printed and labeled by day.
  • Fill in the substitute info sheet with your schedule, signals and helpers, and keep it at the front.
  • Choose review over new content. A substitute can run practice well; teaching a new skill is much harder.
  • Write the projector pages' addresses on the plan in full, so the substitute doesn't have to search.
  • Leave a list of two or three reliable student helpers by first name, and your attention signal.

Questions teachers ask

What should I leave for a substitute?
A plan for each part of the day, the materials already printed, your schedule and routines, a seating chart, the names of helpful students and who to ask for help, and a page for notes. The sub plan template covers all of it.
What are good no-prep activities for a sub day?
Reading a story aloud with questions, a passage with questions, a word search or crossword from a ready-made set, math fact games on the projector, brain breaks, and simple class games like twenty questions.
Should a substitute teach new material?
Usually not. Plan review and practice of what the class already knows, so the day goes smoothly and nobody has to unlearn a mistake taught in a rush.
