“Online timer”: http://www.dadsworksheets.com/timer.html is great for use as a classroom timer, cooking timer, test timer or any other type of countdown timer you can think of. The ‘Zoom’ button simplifies the timer display and makes this timer work very well on projectors or smart boards in the classroom. The timer will countdown in seconds, MM:SS or HH:MM:SS format. You can choose a sound that will play when the countdown timer starts, one that plays when the countdown reaches the halfway mark, one that plays when the timer is near the end, and a final sound that plays when the countdown timer expires.
The cuckoo clock audio is my favourite!
