Primary 1 Mathematics Quiz - Time: Answer Key (Version 1)
Total Marks: 40 | Duration: 45 minutes
Answer 1.
Answer: Seven o'clock (also accept "7 o'clock"). (1 mark)
Teaching note: On a digital clock, 07:00 means 7 hours and 00 minutes. When the minutes show 00, we say the time as "o'clock".
Common mistake: Writing "seven thirty" — remind students that 00 minutes means no minutes have passed.
Answer 2.
Answer: h (1 mark)
Teaching note: "h" is the abbreviation for hours and "min" for minutes. Since 1 hour = 60 minutes, the statement must read 1 h = 60 min.
Common mistake: Writing "min" — check that students know 60 minutes makes one whole hour.
Answer 3.
Answer: 30 min (1 mark)
Method: Half an hour means half of 1 hour. Half of 60 min = 30 min.
Teaching note: Connect to the clock face — the minute hand moves from 12 to 6 in half an hour.
Answer 4.
Answer: B — Eating breakfast (1 mark)
Teaching note: Morning events happen before

Answer 4.
Answer: B — Eating breakfast (1 mark)
Teaching note: Morning events happen before noon. Dinner and going to bed happen in the evening or at night.
Answer 5.
Answer: 9 pm (1 mark)
Teaching note: Times after 12 noon and before midnight use pm. Going to bed at night is pm; 9 am would be morning.
Answer 6.
(a) Three o'clock (b) 3 h 00 min (2 marks: 1 each)
Teaching note: Minute hand points at 12, so it is exactly 3 o'clock. In digits, write 3 h and 00 min.
Answer 7.
Answer: 7 h 20 min (2 marks)
Teaching note: The minute hand points at 4, which means 20 minutes past. The hour hand is a little past 7, so the time is 20 minutes past 7.
Common mistake: Writing 7 h 04 min — teach that each numeral on the clock stands for 5 minutes.
Answer 8.
(a) Half past twelve (also accept "twelve thirty") (b) 12 h 30 min (2 marks: 1 each)
Teaching note: When the minute hand points at 6, the time is half past. The hour hand is halfway between 12 and 1, so it is half past 12.
Answer 9.
(a) 10 h 45 min (b) 15 min (2 marks: 1 each)
Teaching note: The minute hand points at 9, meaning 45 minutes past 10. From 10:45 to 11:00 there are 15 minutes left, so it is a quarter of an hour to 11 o'clock.
Answer 10.
Answer: Hour hand halfway between 8 and 9; minute hand pointing straight down at 6. (2 marks)
Marking guide: Award 1 mark for the minute hand correctly on 6, and 1 mark for the hour hand placed between 8 and 9 (not exactly on 8).
Common mistake: Drawing both hands on 8 and 6 — remind students that at half past, the hour hand has moved halfway to the next number.
Answer 11.
Answer: Hour hand pointing at 4; minute hand pointing straight up at 12. (2 marks)
Marking guide: Award 1 mark for each correctly drawn hand. The hour hand should be shorter than the minute hand.
Answer 12.
(a) am (b) pm (2 marks: 1 each)
Teaching note: Breakfast is in the morning (am); dinner is in the evening (pm). Both times show 7 on a clock, so am/pm tells us which part of the day it is.
Answer 13.
(a) 3 h 15 min (b) One hour forty-five minutes (2 marks: 1 each)
Teaching note: Abbreviations use "h" for hours and "min" for minutes. For words, read the hours first, then the minutes.

Working: Jia Wen stops flying at 9:30 am. She rests for half an hour: 9:30 am + 30 min = 10:00 am.
