 In both the pictures we see 8:00 on the clock. But one is morning and
the other is night time. We add AM and PM to show this difference.

8:00 AM 8:00 PM

Digital clocks help us read the time more clearly.

08:00 20:00
Read the following table and see how we read and write time using
AM/PM and the digital clock. Discuss what you notice about the two
different ways.

Note for Teacher: Help children understand the difference between AM and
PM and how it eases communication about time among people. You may seek
children’s routine experiences and associate them with AM and PM. You may draw
their attention to the 24-hour clock and how it shows time and make children
practice reading and writing it.
