Know:

  • the features of a clock

  • the small hand of the clock represents the hour

  • the large hand of the clock represents the minutes

  • the numbers on the face of the clock represent 5-minute intervals.

Understand:

  • that clocks are used to tell the time of the day.

Do:

  • I can use a clock to tell the time to the minute.

Clocks

We use a clock to help us identify the time of the day.

A clock has a couple of features:

  • A small hand

  • A large hand

  • Numbers around the outside

The small hand of the clock represents the hour of the time.

The large hand of the clock represents the minute of the time.

The numbers are used to represent the hours and minutes.

Remember every hour has 60 minutes, so when you are looking for the minutes of an hour you have to use your counting skills to count by 5s.

When the minute hand is on the 1 it means there are 5 minutes, when the minute hand is on the 2 it means there are 10 minutes, when the minute hand is on the 3 it means there are 15 minutes and it keeps going until you hit the 12.

Using a Timeline to Calculate Time Duration

One efficient method of calculating time duration is using a timeline.

In this example, we are trying to figure out how much time is between 2:55 am and 5:41 am.

  • The first step is to round the minutes to the next closest hour. I would need to add 5 minutes to turn the 55 minutes to 60.

  • Then I can work out the hour difference from 3 am to 5 am there are 2 hours that passed by.

  • From 5:00 to 5:41 there are another 41 minutes that passed by.

  • So now all I have to do is collect up the hours, 2 hours, then collect up the minutes 5 + 41 = 46 minutes.

  • So I know that 2 hours and 46 minutes passed by between 2:55 and 5:41.
