We are learning to solve problems with am and pm notion.


I know I am successful when we can confidently explain the difference between am and pm times.

The most important part of the day

We measure time in two different ways:

1. 24-hour time

2. 12-hour time.

24-hour time is measured from 0:01 in the middle of the night to 23:59 in the middle of the following night.

12-hour time simplifies this and divides the 24 hours in a single day into two parts: before midday and after midday!

What's so special about midday?

The word midday comes from the Latin word, meridiem.

We talk about hours before midday as being ante meridiem or am for short! For example, 7am is seven in the morning.

We talk about hours after midday as being post meridiem or pm! For example, 7pm is seven in the evening.
