THE HANDS OF TIME
Count the numerals on the clock. There are only 12 hours on a clock face. So, the hour hand is a short hand.

“Hour” is a short word. The hour hand is the shorter hand.
hour
“Minute” is a long word. The minute hand is the longer hand.

When the minute hand is pointing to 12, read the time as “o’clock”.
In this case, the hour hand is pointing to the 3 and it is “three o’clock”.
Now the
minute hand is
pointing to 12
and the hour hand is pointing to the 5.
So, we read the time as
“five o’clock”.
FOUR QUARTERS
A clock divided into 4 equal sections,
4 QUARTERS. Each quarter would represent a 15 minute section.
