#### Worksheet Overview

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

 12-hour clock 24-hour clock 1am 01.00 2am 02.00 3am 03.00 4am 04.00 5am 05.00 6am 06.00 7am 07.00 8am 08.00 9am 09.00 10am 10.00 11am 11.00 12pm (noon) 12.00 1pm 13.00 2pm 14.00 3pm 15.00 4pm 16.00 5pm 17.00 6pm 18.00 7pm 19.00 8pm 20.00 9pm 21.00 10pm 22.00 11pm 23.00 12am (midnight) 00.00

If I get on the first bus from Ewood, what time will I get to Darwen cemetery? Give the answer in the 12-hour format.

Step 1: Look for the first bus available from Ewood...07:35

Step 2: Travel vertically down the timetable until you reach Darwen cemetery, the bus arrives there at 08:22

Step 3: Convert from 24-hour digital time to 12-hour clock = 8:22am

Over to you now to have a go at answering some practice questions!
