Classroom Timers

I use timers quite often to keep my kids on task and to give them a deadline. They also keep me on task. There are a handful of good ones out there including e.ggtimer.com, which has been my favorite for a long time because it's so simple. There's few others I've also used with good results but I also like Teachit Timer that I came across today. It has a few neat features like the ability to have a clock and countdown timer on the same screen, or count up and down timers together. You can also customize the sound it plays when it finishes. The clock is ticking...dial it in!
