Learn to read, tell the time and write the time from analogue  (Page 2/4)

Now (on the cutting page) cut out the second circle. Mark in the hours as you did in the previous circle. Now you are going to mark in the minutes. There are 60 minutes in an hour, so how many minutes will there be between the numbers? Yes, 5, i.e. 5 spaces . Put little marks to show them and paste the circle on top of circle number 4. You have made an analogue clock face.

TEST YOUR SKILLS: ANALOGUE CLOCKS

1. Below each of the following clocks, write the time:

1. On the following clock faces, draw in the long and the short hands carefully to show the time that has been written below:

• 22 minutes past 2

2.2 17 minutes to 10

(Did you remember that the hour hand is also moving, very slowly?)

2.3 a quarter to four

2.4 twelve o’clock

Analogue clocks cannot tell us whether it is morning or afternoon. We have to say it is 9 o’clock in the morning, or 4 o’clock in the afternoon. We use the following short forms:

a.m. = in the morning

p.m. = in the afternoon

E xample:

A short way of writing 42 minutes past 10 o’clock in the morning is: 10.42 a.m. A short way of writing 36 minutes past 6 o’clock in the evening is: 6.36 p.m.

Activity 2:

• To learn to read, tell and write the time from digital and 24-hour clocks and stop watches [LO 4.1]
• To use time measuring instruments, including watches and clocks [LO 4.3]

• Digital clocks tell how many hours and minutes have passed since midnight. They work from midnight to midnight; 24 hours. This is useful because as soon as we see more than 12 hours, we know the time is past noon, e.g.
• 08:35The first two digits, the 08, tell us the hour if the hour is less than 10.The last two digits tell us the minutes past the hour

This clock says 35 minutes past 8 o’clock in the morning (the 08 is less than 12).

Midnight would be 24:00.

One minute past midnight may be written as 00:01 or 24:01.

Noon or midday would be 12:00.

One minute past noon would be 12:01.

1. Write as digital time:

• ten past five in the morning:
• twenty past four in the afternoon:
• a quarter to ten in the evening:
• three minutes to one in the morning:
• 8 p.m.
• one minute to ten a.m.

Study this example of a digital clock:

16:15

It shows the time, 4.15 p.m.

2.Now read the time on the analogue watch and write it correctly on the digital watch (in the frame on the right):

2.1

(in the morning)

2.2

(afternoon)

3. Draw hands on the analogue clock face to show the same time as is shown on the digital clock. Then write the time below the analogue clock to indicate if it is morning or afternoon. (Use the short form.)

13.50

09.10

A twenty-four hour clock/ international clock

An international clock is based on the same idea as the digital clock.

This clock also works from midnight to midnight.

The half of the clock face on the right shows time before noon (midday).

The left half shows time from noon to midnight.

4.By looking at this clock, how would you know that the time shown on it is in the morning?

A Stop-watch.

We use this at swimming galas and athletics and other sports events because we have to measure decimal fractions of a second!
