9.3

Digital times and times in words

Level 2
Tell the time in digital form, Say the time in words

In digital form the hour comes first, then a colon, then the minutes.

So 7 o'clock is 7:00, and half past 4 is 4:30. Always write two digits for the minutes.

Key ideas

  • Digital time: hour : minutes.
  • o'clock is :00.
  • Half past is :30.
Worked example 9.3.1
Write seven o'clock in digital form.

Method. Digital time shows the hour, then a colon, then the minutes.

  1. Write the hour. The hour is the number before the colon.
    7
  2. Write the minutes. O'clock means zero minutes, so the minutes are 00.
    00
  3. Write the time.
    7:00

Check. Read 7:00 aloud: seven and zero zero minutes.

Watch out. Always write two digits for the minutes, like 9:05 and 9:30.

Worked example 9.3.2
Write half past four in digital form.

Method. Digital time shows the hour, then a colon, then the minutes.

  1. Write the hour. The hour is the number before the colon.
    4
  2. Write the minutes. Half past means 30 minutes after the hour, so the minutes are 30.
    30
  3. Write the time.
    4:30

Check. Read 4:30 aloud: four and thirty minutes.

Watch out. Always write two digits for the minutes, like 9:05 and 9:30.

Worked example 9.3.3
Write 9:30 in words.

Method. Read the hour first. Then say whether it is o'clock or half past.

  1. Read the hour. The number before the colon is the hour.
    9
  2. Read the minutes. 30 means half past. 00 means o'clock.
    30
  3. Write the time in words.
    half past nine

Check. The digital time 9:30 matches half past nine.

Watch out. Half past is 30 minutes. o'clock is 00 minutes.

Watch out

Watch out. 4:30 is half past 4. It is not 4:3 or 30:4.

Exam tip

Grown-up tip. Look at a digital clock together. Read each time aloud, the hour first and then the minutes.
