Understanding Different Timetables using the 12-hour and 24-hour format (2)

Great job, you have decided to spend some time practicing for the KS2 SATs Maths test.

 

This activity will help you to learn how to read timetables using the 12-hour and 24-hour format.

 

You will also be asked to convert between the 12 and 24-hour clock format.

 

What is the 12-hour format?

The 12-hour clock runs from 1am to 12 noon and then from 1pm to midnight.

 

What is the 24-hour format?

The 24-hour clock uses the format 00:00 to 23:59. Remember that midnight is 00:00

 

 

In order to switch from a 24-hour clock to a 12-hour clock, you simply need to subtract 12.

So 17:00 becomes 5:00 because 17 - 12 = 5
