Brain breaks for the classroom — your class controls them by moving

Setup in 30 seconds

1. Open kamgem.com/?brainbreak=3 on the classroom laptop or tablet and put it on the projector or smartboard — that link starts a three-minute Brain Break on its own, or use the Brain Break buttons on the home page to pick 2, 3 or 5 minutes.
2. Turn the laptop (or external webcam) to face the open space where kids will move.
3. Pick a game, press Start, allow the camera — and call the class up.

What the three lengths actually run

Every run has the same shape — a warm-up, one to three main games, then something calm to finish — but the games themselves rotate daily, so a class that has one every afternoon does not get the same break five times a week. Each run is drawn from three pools, and every game in all three is whole-class by design.

• Warm-up — Stop & Go or Limbo. Out of chairs, one rule, nothing to explain.
• Main — Bubble Pop, Whack-a-Mole, Pinata, Dodgeball or Bird Chase. Scored and co-operative: the whole class pushes one number up.
• Finish — Snow, Bubble Wrap or Aquarium. No score and no timer, so the class is calmer leaving than arriving. Every length ends on one of these.

You do not have to guess which you will get: today's run is printed on the Brain Break card on the home page before you press anything.

• 2 minutes — three games of about 38 seconds. Enough for a transition between two lessons.
• 3 minutes — four games of about 43 seconds.
• 5 minutes — five games of about 58 seconds. Long enough for indoor recess.

The slot length is the requested time divided by the number of games, minus the three-count before each one — which comes out of the budget rather than being added to it, so "3 minutes" finishes in three minutes.

While it runs, a clock band sits in its own strip above the game rather than on top of it, showing the time left, the game that is playing and what is next. It is sized to be read from the back of the room.

The length is a promise, not an estimate. If the class loses all its lives in Stop & Go after twenty seconds, that game restarts inside its own slot instead of cutting the break short.

If you are planning around a particular child, the warm-up is the slot to check: Stop & Go asks the room to freeze, and Limbo asks it to crouch. Today's warm-up is named on the Brain Break card before you start, so you can see which one you have and hand-pick instead if it is the wrong one that day.

The run ends on a full-screen Back to work! card, so the instruction arrives from the projector instead of from you over the noise — leave it up while they sit down. The Stop button ends a break early if you need the room back.

Best whole-class picks

One webcam, twenty-eight children

The games do not track individual players. Each frame is compared with the one before it and the game reacts to whatever changed, so nobody has to stand in a special spot and nobody needs a controller. But the camera counts pixels, not children: a child nearer the lens fills more of the picture and counts for more. That is the whole reason framing matters.

• The camera's view is the play area. The class is drawn on screen inside the game, so the projector shows you your own framing — a child outside that picture is moving for nothing.
• Two loose rows beat a crowd. Keep an arm's length between children and stop them drifting forward, or the nearest child fills the frame and the rest stop counting.
• Half the class at a time in a small room. A Brain Break rolls straight from one game into the next with no pause, so swap groups between breaks rather than mid-run — or press Stop and start a fresh one.
• Press F, or the Fullscreen button. On a projector the browser toolbars are wasted space and the clock is what you want big.
• Press M to mute. Every game in a Brain Break has music except Confetti — welcome in a brain break, less welcome when the class next door is testing. You only press it once: the browser remembers the setting for the rest of the run.
• Lights on, blinds down. The camera has to see movement, so dim the room for the projector without dimming the children.

If a child can't take part

Nothing in a Brain Break has to be jumped, and nothing keeps a per-child score. A seated child's wave counts, the same as a standing child's jump does — it is just a smaller part of the picture, so seat them near the camera. Bubble Pop, Pinata and Confetti suit that best: they score reaching rather than jumping, and Confetti scores nothing at all. Stop & Go is the exception, because it reads the whole room's stillness on red, so one child who cannot hold still costs everyone a life.

A child who should not be on camera stays out of the frame: behind the laptop, or at a desk running the clock and the Stop button. There is no image of anyone either way, because nothing is recorded, saved or uploaded.

When what the room needs is a calm-down rather than a wiggle — after lunch, on a wet play day, in the ten minutes before a test — skip the sequence and open a scene instead. Snow, Aquarium, Magic Garden and Frost Wipe have no score, no timer and no way to lose. The three scenes that use bright flashing effects — Lightning, Disco and Fireworks — are never part of a Brain Break; full-screen flashes elsewhere are rate-limited to stay under photosensitivity guidelines and switch off entirely when the device has reduce-motion turned on. The safety notes have the detail.

What your IT department will ask

• Does the video go anywhere? No. Frames are compared inside the browser and discarded. Nothing is recorded, saved or uploaded.
• Do children have accounts? There are none. No sign-in, no email address, no class code, no roster to import.
• What leaves the device? One anonymous counter when a game ends: which game, how many seconds, and a coarse 0/1/2 bucket for whether this browser has played before. No names, no identifiers, no cookies, no analytics scripts, no ad network. The only other thing ever sent is a feedback message someone chooses to type, and those are redacted before storage and deleted after 90 days.
• What stays on the laptop? Best scores, a short play log and achievement unlocks, in the browser's own storage — never transmitted, and cleared with the site's browsing data. Nothing identifies a child.
• What has to be installed? Nothing. It is a web page in a normal browser — no extension, no plugin, no purchase.
• You can check it yourself. Start a Brain Break and unplug the network. It keeps playing, because nothing was being sent.
