22 Silent Classroom Countdown Timers

Stop hunting for a timer mid-lesson. This bundle gives you 22 ready-to-go countdown timers covering every length you’ll need from a quick 30-second challenge to a full 20-minute task. Clean, silent and distraction-free, they drop straight into your slides and run automatically.

What you get, 22 timers:
30 seconds · 1 min · 1 min 30 · 2 · 3 · 4 · 5 · 6 · 7 · 8 · 9 · 10 · 11 · 12 · 13 · 14 · 15 · 16 · 17 · 18 · 19 · 20 minutes.

Each timer comes in two versions:
