Counting Down.....3,2,1 or Up

Timer from Class Tools - Need help with classroom management, or just want the kids to see how much time is left on a particular project? Use a countdown clock and project it on the board. Want to use an online stopwatch? Here's a site Custom Countdown that lets you set your own custom times and sounds. Personally, I'm going to try it with book checkout times. I can never get the kids to finish up on time, maybe this will help!
