Students watch and listen to the One Moment Around the World video on the British Council website. After the clip, discuss with the class:
- why the clip showed people from all over the world
- the different activities that the characters were doing
- how all of these things might be happening at the same time.

Display slides 5-6 of the Time After Time Mathematics PowerPoint. As a class, discuss:
- why the numbers 12 and 24 are used in time
- why we have am and pm time
- the structure of time during the day.

Display slide 8. Discuss the problems on the slide and write some ideas for calculating the answers on the board. Take note of:
- the am and pm time
- the units of time involved
- times which are off the hour.
Discuss the concept of times zones, as outlined on slides 9-10. Provide the students with a copy of the Time After Time Worksheet. Monitor and support the students as they answer the questions about countries and time zones around the world.

Once the worksheet has been completed, discuss the answers as a class. Encourage more confident students to model their calculations on the board.
