Telling the Time on a Clock - Cycle 2

How Does a Clock Work?

Be careful!

To learn how to tell time, it is important to understand the role of the hands and the numbers on a clock. For a reminder, consult The Clock concept sheet.

While the big hand is moving around the clock, the little hand slowly moves closer to the next number. The hour changes when the big minute hand has fully moved around all the dots or dashes on the clock (60 minutes).

Example

In these examples, the further the big minute hand moves, the closer the little hand approaches to 8:00.

Be careful!

When the big minute hand has almost finished its rotation around the clock, the little hour hand is very close to the number that indicates the next hour.

Example:

Looking at the small hand in this image, we may think that it is 5:00.

Nevertheless, the minute hand has not fully completed its rotation around the clock. There is 1 minute left.

To know the hour, you must look at the previous number. It is 4:59.

How do we Tell the Time on a Clock?

Rule

I have to follow these steps to tell time on a clock.

  1. I look at the number indicated by the little hand to know the hour.
  2. I look at the big hand to see how many minutes have passed since the start of the hour.
Example

What time is it on the following clock if it is the morning?

Horloge qui indique dix heures et vingt-quatre minutes-1

  1. I look at the number indicated by the little hand to know the hour.

    It is the morning. The hour hand is pointing between 10 and 11. Therefore, it is still 10 o’clock.

  1. Then, I look at the big hand to see how many minutes have passed since the start of the hour.

    I know that 24 minutes have passed since the start of the hour since the big hand is pointing at the 24th dot or dash.

It is 10:24.
