You already know how to read a clock and tell o'clock and half past times. Now let's learn two facts that make time easier: how many minutes make one hour, and how many hours make one whole day.
Grace watches a show that lasts 60 minutes. She says, 'That show lasted exactly 1 hour!' She is right, because 60 minutes and 1 hour are the same amount of time.
For any number of hours, multiply by 60 to get minutes. Two hours is 60 + 60, which is 120 minutes.
One hour is 60 minutes, and one day is 24 hours.

Converting units of time review (seconds, minutes, & hours)
Time can be measured in seconds, minutes, and hours.
A second is very short. It takes about 1 second to snap your fingers.
A minute is longer. 1 minute equals 60 seconds. It takes about 1 minute to brush your teeth.
An hour is even longer. 1 hour equals 60 minutes. You might spend 1 hour at swim practice or a piano lesson.
Knowing these facts helps you figure out how long things take, like a car ride or a movie.
Telling time review
A clock shows the time using hours and minutes.
The short hand on a clock is the hour hand. The long hand is the minute hand.
If the hour hand points near the 9 and the minute hand points at the 39 minute mark, the time is 9:39. That means it is 39 minutes after 9 o'clock.
Remember, there are 60 minutes in every hour, so the minute hand goes all the way around the clock once each hour.
