# A visual timer for the classroom A countdown the whole class can read, with color changes as time runs low — on the projector or smartboard, free of installs, controlled from the teacher's desk. A visual timer changes classroom behaviour in a way spoken time warnings never do: when students can see time passing — and see it change color as the end approaches — transitions happen without repetition and timed work paces itself. The teacher stops being the clock. MaestroTimer puts that visual countdown on whatever screen the classroom already has: the projector, the smartboard, or a spare monitor. It runs in the browser, so there is nothing to install on school devices — a link opens, the timer fills the screen. ## Put the timer on the board The setup survives any classroom's IT reality because it is only a web page. The steps: 1. Create a room and add timers for the day's blocks — "Group work", "Clean-up", "Quiz" — each with its own duration. 2. Set wrap-up thresholds: the display changes appearance as time runs low, which is the "visual" part doing its work. A five-minute warning and a one-minute warning suit most activities. 3. Open the room's viewer link in the browser on the classroom display and make it fullscreen. 4. Keep the controller open on the teacher's device — desk computer, tablet, or phone — and run the day from there. ## Timers by activity Different classroom moments want different clocks. The patterns: - Transitions: short countdowns with an early warning — the color change moves the room before the zero does. - Independent and group work: longer countdowns; students self-pace against the visible remaining time. - Tests and quizzes: a countdown everyone can see keeps time-checking off the teacher's plate, silently. - Discussions and presentations: count-up mode shows elapsed time when a hard deadline would pressure the wrong things. - Recurring daily blocks: keep the room and reuse it — the timers persist from day to day. ## Why visual beats spoken warnings A spoken "five minutes left" reaches students once, in the middle of whatever they were attending to. A visible countdown is available continuously — each student checks it when they are ready to, and the color stages convert time from an abstraction into something readable at a glance. That continuous availability matters most for students who struggle with time perception: the display answers "how long do I have?" without requiring anyone to ask. ## Works inside school IT constraints Classroom technology has rules: no installs on managed devices, filtered networks, shared hardware. A browser timer fits inside all three — it is a website, so Chromebooks, smartboards with browsers, and locked-down desktops all display it without administrative rights. For remote or hybrid classes, the same viewer link goes to students at home: everyone sees the identical countdown, and the live connections view shows the teacher which screens are attached. ## FAQ ### Does the visual timer work on a smartboard or Chromebook? Yes. Anything with a browser displays it — open the viewer link and go fullscreen. Nothing is installed, so managed school devices need no special permissions. ### Can students see the timer change as time runs out? Yes — wrap-up thresholds change the display's appearance at times you set, so the class gets a visual warning stage before zero. ### Can I control the timer without touching the board? Yes. The controller view runs on the teacher's own device; start, pause, and time changes appear on the classroom display immediately. ### Does it work for remote or hybrid classes? Yes. Students at home open the same viewer link and see the same live countdown as the classroom screen. **Put time on the board** — MaestroTimer runs in the browser: a fullscreen visual countdown on the classroom display, staged color warnings, and control from the teacher's desk.
