Say what happens at zero

Tell students whether the alarm means stop, submit, switch stations, or prepare for the next instruction.

Test the alarm first

Choose a sound and test it before the room becomes busy. Use no sound for silent reading or assessment periods.

Use fullscreen

Fullscreen removes page distractions and makes the remaining time readable from the back of the room.

Keep transitions realistic

Choose a duration that includes packing away and movement, not only the core activity.
