There are two types of clock, the 12-hour clock and the 24-hour clock.
The 12-hour clock runs from 1 am until 12 o'clock noon, and then from 1 pm to 12 o'clock midnight
The 24-hour clock runs from 1 am until 12 o'clock midnight.
In this activity, we are using the 12-hour clock.
Clocks have an hour hand and a minute hand (and sometimes a second hand)
The hour hand is shown in red. It is SHORTER.
The minute hand is shown in blue. It is LONGER.
The hour hand uses the numbers shown on the clock face.
It is pointing to between 10 and 11, so we know it is after 10 o'clock but before 11 o'clock.
The minute hand does not use the numbers on the clock face.
We must multiply them by 5 to get the minutes.
It is pointing to 4 which is really 4 x 5 = 20 minutes.
So the time shown is 10:20
