Thirty minutes with a visible finish.
This thirty minute timer is ready for longer independent work, assessments, project time, centers, or a full classroom activity block. Students can see the remaining time without interrupting the lesson.
Switch to Count Up to show elapsed time, add a preset classroom message, or use the dedicated fullscreen presentation when the timer needs to dominate a projector or smartboard.
