Classroom Timer

The classroom timer opens at five minutes and is built for the front of the room: a large fullscreen display and a traffic-light colour cue that lets students read the remaining time at a glance.

This page adds real classroom features on top of a normal timer. Use the fullscreen button to fill a projector or board, and the built-in traffic light shifts from green to amber to red as time runs down — paired with a text label so it never relies on colour alone.

Tips for classroom use

Press the fullscreen button and project the timer where everyone can see it.
Explain the task before you start so the countdown sets the pace.
Watch the traffic light shift to amber and red as a shared "wrap up" cue.
Reset between groups or stations to reuse the same block.

Frequently asked questions

What makes this different from a plain 5 minute timer?

It starts at five minutes like a normal timer, but adds a projector-friendly fullscreen view and a green–amber–red traffic-light state so a whole class can gauge the remaining time without reading the digits.

Does the colour cue work for colour-blind students?

Yes. The traffic light is always paired with a text label (such as "Plenty of time" or "Almost out of time"), and the exact countdown stays visible, so the state never depends on colour alone.

Is this an official exam or testing timer?

No. It is a general classroom countdown and makes no claim of official exam or testing compliance.

Can students use it on their own devices?

Yes. It works in modern browsers on phones, tablets, laptops, and classroom displays.
