O'clock, half past and hours worksheet: Answers and working
Part A: Working out and filling in
1. 12 o'clock
Look at the minute hand first: on 12 means o'clock. Then see which number the hour hand points to.
The minute hand on 12 means o'clock, and the hour hand is on 12: 12 o'clock.
2. 12 o'clock
Start at 4 o'clock. Each hour, the hour hand moves on one number. Move it on 8.
Count on 8 hours from 4: 4 + 8 = 12, so 12 o'clock.
3. 8 hours
The hour hand moves from 2 to 10, an hour for each number. Count how many numbers it moves.
The hour hand moves from 2 to 10: 10 − 2 = 8 hours.
4. 4 hours
The hour hand moves from 5 to 9, an hour for each number. Count how many numbers it moves.
The hour hand moves from 5 to 9: 9 − 5 = 4 hours.
Part B: Choose, or true or false
5. C. Half past 10
Look at the minute hand first: on 6 means half past. Then see which number the hour hand has just passed.
Minute hand on 6: half past. The hour hand is between 10 and 11: half past 10.
6. C. o'clock, hours
“O'clock” tells a time on the clock; “hours” tells how long something takes. Which does each bracket need?
“1 o'clock” is when it starts, read off the clock; “1 hours” is how long it lasts, a length of time.
7. A
For 8 o'clock, where should the minute hand point? And the hour hand?
8 o'clock: minute hand on 12, hour hand on 8.
8. D. o'clock, hours
“O'clock” tells a time on the clock; “hours” tells how long something takes. Which does each bracket need?
“3 o'clock” is when it starts, read off the clock; “1 hours” is how long it lasts, a length of time.
9. D
For 4 o'clock, where should the minute hand point? And the hour hand?
4 o'clock: minute hand on 12, hour hand on 4.
10. True
Work out each child's hours: Chi-keung from 7 to 9, Tsz-ching from 5 to 6.
Chi-keung plays 9 − 7 = 2 hours, Tsz-ching plays 6 − 5 = 1 hours.
11. C. Tsz-ching gets up at 6 o'clock in the morning.
For each sentence ask: is it a time on the clock, or how long something takes? A time is “o'clock”; how long is “hours”.
Getting up happens at a time on the clock, so “6 o'clock” is right. How long you sleep or practise is a length of time, “hours”; when lunch is eaten is a time, “o'clock”.
12. True
Work out each child's hours: Ka-yee from 2 to 5, Ming from 9 to 10.
Ka-yee plays 5 − 2 = 3 hours, Ming plays 10 − 9 = 1 hours.
Part C: Word problems
Marking: 2 for the working, 1 for the answer, 1 for the sentence.
13. 3 hours
First work out how many hours Chi-keung hikes: from 5 o'clock to 9 o'clock.
Then compare that with Tsz-ching's 1 hours, taking the smaller from the bigger.
Chi-keung hikes 9 − 5 = 4 hours, 4 − 1 = 3 more than Tsz-ching.
14. 9 o'clock
Start at 6 o'clock and count on 3 hours.
Count on 3 hours from 6: 6 + 3 = 9 o'clock.
15. 2 hours
From 10 o'clock to 12 o'clock, how many numbers does the hour hand pass? Each one is an hour.
12 − 10 = 2 hours.
16. 4
One hour later the hour hand moves on one number. Count on an hour from half past 3.
One hour on, the hour hand moves on one number: half past 4.
17. 7 o'clock
Start at 5 o'clock and count on 2 hours.
Count on 2 hours from 5: 5 + 2 = 7 o'clock.
18. 2 hours
First work out how many hours Ka-yan hikes: from 6 o'clock to 11 o'clock.
Then compare that with Ming's 3 hours, taking the smaller from the bigger.
Ka-yan hikes 11 − 6 = 5 hours, 5 − 3 = 2 more than Ming.
