The Chuckle Brothers explain how to read the time on an analogue clock to the nearest 5 minutes. They also show how to calculate time intervals and find start or end times for a given time interval.
If pupils are already able to tell the time and this takes the form of revising or consolidating their learning on time, they could be asked to attempt to write a letter explaining to Barry how the clock works and why he was wrong when he said that it was "one past five". If pupils are in the process of learning how to tell the time, they could be given their own miniature clocks to follow along with whilst watching the clip. At an appropriate point, the clip could then be paused and pupils asked to display on the clock the time that they think the awaited guest will arrive. Each person could be asked to say out loud or write on a mini whiteboard, the time they have predicted.
