3 Minute Timer
The standard length of saying your piece — presentations, quickwrites, and a break long enough to count.

Three minutes is a presentation
Three minutes is the length the world has settled on for "explain your thing". The Three Minute Thesis competition asks doctoral researchers to present an entire dissertation in three minutes with a single static slide. Lightning talks at conferences run to roughly the same limit. In a classroom it scales: a beginning, a middle and an end fit into three minutes, and a class of thirty can hear ten of them inside one period with time left for questions.
It is also the natural length for a book talk, a show-and-tell, or a group reporting back after a task. Project the countdown behind the presenter and the job of cutting someone off stops being yours — the clock does it, visibly and fairly, and the next student is already standing up.
Quickwrites, stations and breaks
A three-minute quickwrite is a common way to start a writing block: pens down at zero, no editing, whatever comes out is the draft. The short window is what stops students from stalling on a first sentence. The same three minutes runs a station in a centers rotation when you want students to hit many stations rather than settle into a few.
Three minutes is also the shortest span that works as a genuine brain break — long enough to stand up, stretch, and reset, where a single minute is only long enough to be interrupted. Outside school the number shows up in steeping tea, resting a plank, and guided breathing exercises, all for the same reason: it is short enough to commit to without thinking about it.
Embed this timer
For a presentation day, embed this timer once at the top of the running order page and reset it between speakers rather than generating a new link for each. The embed counts down from the moment the code is created, so create it as the first presenter walks up.
Frequently asked questions
How many three-minute presentations fit in a class period?
Allow about four minutes per student once you include walking up, setting up, and a question. In a 45 minute period that is roughly ten presentations; in a 60 minute block, closer to fourteen. Timing the transitions is usually what decides it, not the presentations themselves.
Can I run several three-minute rounds back to back?
Yes. Press Reset and then Start Timer again — each round begins from a full three minutes. Nothing is stored between rounds, so there is no history to clear and no limit on how many you run.
Why does the clock show minutes and seconds rather than hours?
Every page in this section is a short timer, so the display is fixed to minutes and seconds. Three minutes reads as 03:00 and counts down to 00:00 — no leading zeros for hours that would never be used.
