Classroom Resource: Countdown Timer
This term my school is running some maths competitions involving timed rounds.

Not particularly flashy, but it gets the job done!
You can start/stop/reset the countdown, and alter the starting count in 30s increments, just by pressing buttons, which makes it easy to use on an Interactive Whiteboard.
