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. 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. Digital clocks help us read the time more clearly. 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. 8:00 AM 8:00 PM 08:00 20:00 Chapter 12.indd 179 Chapter 12.indd 179 3/26/2025 4:16:54 PM 3/26/2025 4:16:54 PMRead More
