Large display, silent action, easy-to-set, easy-to-read
Invented by a mother to help her daughter get ready for pre-school, the Time Timer is a wonderfully simple tool. The large clock face enables it to be seen from across the room while the red "pie shape" provides a quick sense of the time remaining.
Although this timer doesn't emit a beeping sound like the digital timer, the advantage is that my students can see if from across the room.
Tip: If I want to be alerted to the fact that the time is up, I'll sync my digital timer to go off as the red dial is disappearing.

The Time Timer company no longer makes the version I thought was the best so we've decided to stop carrying them in our online store.
