About this 15 minute timer
Use this 15 minute timer for longer stretches: a short quiz, a writing block or a round of learning centers. Fifteen minutes is a natural quarter of a lesson, and the shrinking ring makes it easy to see how much is left.
The timer runs from the real clock, so it stays accurate if you open your slides or class list in another tab. A soft bell, chime or beep marks the end.
