View full screen in your browser. This ITP displays on-screen analogue and digital clocks separately or together. The clocks can be moved around the screen and their sizes altered. Times can be adjusted in different intervals of time. The ‘set’ option on the digital clock is used to set the time shown on the clocks. Once you have selected your options click on ‘set’ again to restart the clocks. The clocks can run in real time or from a set time and over any interval. The clock can be stopped and started. The ITP can be used to support the teaching of the telling of time, to identify time before and after given intervals and to undertake calculations that involve time.
