An Edutopia article by two educators says a daily read-aloud of only five to seven minutes builds students' enthusiasm for reading and can draw reluctant readers back in. It says read-alouds work for older students too, and in any subject, not just English. ESU 6's substitute toolbox also suggests reading aloud, with picture books for younger classes and poetry or short books for older ones.
No cost; uses only what is in the room
Watch for You need a book; use one from the room or your bag, and stop on an exciting part if time runs out.

Edutopia's list of brain breaks for high schoolers includes would you rather: the class or partners choose between two made-up options and move to one side of the room to show their pick. TeachThought's list of sub activities also suggests it for elementary classes, as an easy way for a sub to get to know students.
No cost; uses only what is in the room
Watch for Moving to sides of the room can get loud; with a lively class, have students show their pick by raising a hand instead.

TeachThought's list of activities for substitute teachers, written by a former teacher, suggests Twenty Questions: one person knows the answer and the class has up to twenty yes-or-no questions to guess it. ESU 6's sub toolbox suggests the same game using places, people or things from the school, city or classroom.
No cost; uses only what is in the room
Watch for A few eager students can take over the guessing; call on hands in turn so more of the class gets a question.

ESU 6's substitute toolbox suggests having students draw a picture of their family, a favorite activity, a favorite food or their after-school plans, then take turns sharing. It needs only paper and pencils, and the sharing helps a sub learn names.
No cost; uses only what is in the room
Watch for Some children may not want to share about family; offer the other topics and let sharing be optional.

Edutopia's brain-break list describes a class rock, paper, scissors tournament: winners keep playing each other until one champion is left. It needs no materials and takes only a few minutes.
No cost; uses only what is in the room
Watch for It ends loud when the final two play, so save it for a moment when some noise is fine, not next to a testing room.

66. Peabody Teach no-prep activity picker
Peabody Teach
This is ours. You pick the grade (K to 8), the minutes left and what the room allows, such as quiet, no paper, no screen, or a wild class that should stay seated. It shows three activities that fit, each with what you need, and does not repeat one until you have seen them all. It is free with no sign-in, and your last choices stay only in your browser.
Free, no sign-in, no ads
Watch for The activities are written by Peabody Teach rather than drawn from research, and it covers K to 8 only, not high school.

A Teachers Network article on sponge activities suggests counting by multiples for early elementary classes, and counting by twos, fives or tens while doing simple exercises for upper elementary. We Are Teachers' tips for subs also suggest counting by twos or fives when you are not sure about the math lesson.
No cost; uses only what is in the room
Watch for Older students may find it too easy; count by larger or odd numbers, or by fractions, to stretch them.

Edutopia's brain-break list suggests invisible pictures: one partner draws a picture in the air while the other guesses it, with yes-or-no questions allowed if they get stuck. It needs nothing at all.
No cost; uses only what is in the room
Watch for It is written for high schoolers, so with younger children model one turn at the front before pairs try it.

99. Conversation starters
ESU 6's substitute toolbox suggests posing open-ended questions for students to answer, such as the most important quality a person can have, or what goal they would chase if anything were possible. They work as a whole-class talk or with partners.
No cost; uses only what is in the room
Watch for Steer clear of questions that pry into home life; keep them about ideas, hopes and favorites.

TeachThought's list of sub activities suggests having students write a letter to a future version of themselves about their life and their dreams. It needs only paper and a pencil and keeps a class quietly busy.
No cost; uses only what is in the room
Watch for TeachThought lists it for high school; younger children can draw their future selves and write one sentence instead.

How we chose
We weighed these, most important first. The order is our judgement against them, not a score or a vote, and a different teacher could reasonably order it differently. Our own tool sits where those criteria put it; we built it after studying the others, so read its entry with that in mind.
- Truly no prep. It needs nothing beyond a book, the board or paper and pencils that are already in the room.
- Works across grades. It can be stretched up or down from kindergarten to high school with small changes.
- Keeps the room calm. Activities that can be run seated or quietly rank above ones that wind a class up.
- Backed by a teacher source. Each one is recommended by an education publisher or a substitute teacher guide.
