Over the years I have found some awesome sites that provide a countdown timer or a stopwatch. Some with an alarm, some without. Some can be used full screen, some in the shape of an egg, and some that were covered with advertisements. And over those years I have had to update blog post after blog post to remove the timer sites that just didn't last. I believe I have finally found an excellent countdown timer that I'm fairly certain will never go away.
Why won't it go away? One word; Google! Google has built the countdown timer in the search interface. Try opening a Google search page by navigating to www.google.com. In the search bar type, "set timer 2 minutes" or I can do it for you if you prefer (let me Google that for you).
Instantly, Google creates a timer that begins counting down.
Notice the ability to stop, reset, adjust notification volume, and display full screen options. This is an excellent tool for any classroom that needs a countdown timer for station work or timed activities. Well done Google.
