Countdown Timers can be used in many ways: clearing up ready for playtime, finishing off work, spelling or tables tests and more.
There are a range of free timers which can be projected on to a whiteboard, which may add a little interest and excitement to various projects. When using a big timer to count down for: timed writing, timed research, timed problem solving etc, there will be no doubt about how much time students still have left for their task.
The ClassTools Timer – A great and very easy to use timer, just type your time straight into the counter, the background changes colour from green, through amber to red as it counts.
Online Stopwatch – There is a great set of fun countdown timers at this site. I quite like this bomb one but can imagine children getting excited by it as it explodes with a loud boom at the end. NB: if you do not clear it, it keeps exploding! It has a digital clock format for setting the timer, when you starts it shows the bomb image.
Web Timer – This one, although a little basic, can be set to timer, or stopwatch and has a number of preset times to choose from. Another good point is that it does not carry any advertising.
