Everyone needs a timer sometimes in class - use it on a whiteboard or projected for starters, timed activities, group work or games. You can even choose your final alert sound - a whistle, a gong, a dog barking... and more....
You can always download the latest version of the Timer from the Teachit site - it's in the Wizzy Things section. Here's a guide from Teachit showing you how to download it.
