The minute hand (longer hand) moves from one small division to the next small division
in 1 minute. It goes around the dial once in 1 hour. So, the minute hand covers 60 small

divisions in 1 hour.
So, 1 hour = 60 minutes

The hour hand moves from one number to the next number in 1 hour.

So, it takes 12 hours to complete one round. The hour hand takes 2 complete rounds in
a day. So, 1 day = 24 hours

Project Creative Thinking

Prepare your own circular clock using a paper plate. Take the help of your
parents or teachers and decorate it with colour pencils or crayons.

Reading the time on the clocks

Reading time in hours Reading time in half hours

When the minute hand points 10 11 12 1 2 When the minute hand is on 6, 11 12 1

to 12, it means the time is 9 3 the time is in half hours. 10 2
exactly on the hour. 8 4 Look at the clock shown 9 3
7 6 5 8 4
In the given clock, the hour alongside. 7 6 5
hand is on 9 and the minute hand The hour hand is between 2 and 3. The
is on 12. minute hand is on 6.

So, the time is 9:00 or 9 o’clock. So, the time is 2:30 or half past 2.

Quarter Past the hour Quarter to the hour

When the minute hand is on 11 12 1 When the minute hand 10 11 12 1 2

3, then the time is a quarter 10 2 is on 9, then the time is a 9 3
past the hour. 9 8 4 3 quarter to the hour. 8 7 6 5 4

In this clock, the hour hand is 7 6 5 In this clock, the hour hand
pointing between 1 and 2. The is little before 5. The minute
minute hand is on 3. hand is on 9.

So, we say that the time is 1:15 or quarter So, we say that the time is 4:45 or quarter
past 1. to 5.

Teacher’s Discuss with the help of examples, that the positions of the minute hand at 3, 6, 9 and 12 11 12 1
Tip are read as quarter past, half past, quarter to and o'clock, respectively. 9 10 2 3
8 4
