Let Us Begin!

Every day you wake up, go to school, eat lunch, and go to bed. All these happen at different times.

We use a clock to know what time it is. A clock has two important hands:

The short hand is the hour hand. It shows the hour.

The long hand is the minute hand. It shows the minutes.

A clock has numbers from 1 to 12 written on its face.

Understanding Time

O'Clock

When the minute hand points to 12 and the hour hand points to a number, we say it is "___ o'clock".

If the hour hand is on 7 and the minute hand is on 12, the time is 7 o'clock.

Half Past

When the minute hand points to 6, it has gone halfway around the clock. We say it is "half past ___".

If the hour hand is between 3 and 4, and the minute hand is on 6, the time is half past 3 (or 3:30).

Think about it: Your school starts at 8 o'clock in the morning. Where will the hour hand and minute hand be on the clock?

a.m. and p.m.

a.m. means the time from midnight (12:00 at night) to noon (12:00 in the afternoon).

p.m. means the time from noon (12:00 in the afternoon) to midnight (12:00 at night).

You go to school at 8:00 a.m. You eat dinner at 8:00 p.m. Same number, different time of day!
