What time will it be in 20 minutes?
The line reads Ends at and the time on this device's clock. Pause and it clears. Resume and it shows the new time. The line stays in the full screen view, so the whole class can read it: press Full screen, or F on a keyboard.
Reading the 20 minute visual timer a quarter at a time
A quarter of the disc is 5 minutes. Four-station rotation gives each round one quarter. Reading conferences gives 4 pupils 5 minutes apiece. Spelling test and check reads 20 words at 45 seconds each, then leaves 5 minutes to swap papers.
- In the last 2 minutes the disc of this radial timer changes color inside a dashed ring.
- Changing tabs leaves full screen, by the browser's rule. Press Full screen again: the 20 minute countdown kept going.
Questions and answers
Is there a 20 min timer with no sound?
Yes. Choose No music in the list beside the main button, which then reads Start the timer. The end sound is off unless you pick one, so this silent timer finishes without a sound: the screen reads Time is up.
Can I set an alarm for 20 minutes?
Yes. For a 20 minute alarm, open More options before you start and pick Soft chime, Hand bell or Wood block from When the time is up. It rings once at 0:00. Test sound plays it at once, so you can check the volume.
Does the 20 minute timer play relaxing music?
It opens on Drift, the slowest of four tracks made in the browser: one soft chord every 4 seconds, no tune and no words. It suits Silent reading block, which hides the digits and leaves only the disc.
Can I use it as a 20 minute classroom timer for stations?
Yes. Choose Two-station swap for 2 turns of 10 minutes, with a tidy warning 30 seconds before the change, or Four-station rotation for 4 turns of 5. Pick it first: Ready-made routines (18) sits under the timer, outside full screen.
Is a 20 minute timer for kids easy to read from the back?
The shape is. Half the disc gone means 10 minutes left, and that reads from anywhere. Single minutes are harder, since each slice is thin, so the digits carry the detail. In full screen the disc and the digits both grow with the window.
