Let’s go through each problem step by step.
We are asked to
round the time to the nearest hour.
That means:
- If the minutes are
30 or more, round
up to the next hour.
- If the minutes are
less than 30, round
down to the current hour.

Part 1: Clocks (Problems 1–6)
We’ll look at each clock, read the time, then round it.
#### Problem 1: Already done as example → 01:00
Clock shows about 12:40? Wait — actually, looking at the hands:
Hour hand is just before 1, minute hand on 8 → that’s 40 minutes past 12 → 12:40 → rounds to
1:00 ✔
But since it’s already given, we move on.
#### Problem 2:
Green clock:
Hour hand between 5 and 6 → so it’s 5 something.
Minute hand on 2 → that’s 10 minutes → 5:10
Minutes = 10 < 30 → round down →
5:00
#### Problem 3:
Orange clock:
Hour hand near 10, minute hand on 4 → 20 minutes → 10:20
20 < 30 → round down →
10:00
Wait — let me double-check:
Actually, minute hand on 4 is 20 minutes? Yes. Hour hand is just past 10 → yes, 10:20 → rounds to 10:00.
#### Problem 4:
Brown clock:
Hour hand near 11, minute hand on 10 → 50 minutes → 11:50
50 ≥ 30 → round up → but 11:50 rounds to
12:00
#### Problem 5:
Purple clock:
Hour hand on 3, minute hand on 3 → 15 minutes → 3:15
15 < 30 → round down →
3:00
#### Problem 6:
Pink clock:
Hour hand between 9 and 10, minute hand on 7 → 35 minutes → 9:35
35 ≥ 30 → round up →
10:00

Part 2: Digital Times (Problems 7–12)
Same rule: round to nearest hour based on minutes.
#### Problem 7: 01:52
Minutes = 52 ≥ 30 → round up →
2:00
#### Problem 8: 06:18
Minutes = 18 < 30 → round down →
6:00
#### Problem 9: 11:20
Minutes = 20 < 30 → round down →
11:00
#### Problem 10: 04:05
Minutes = 5 < 30 → round down →
4:00
#### Problem 11: 12:43
Minutes = 43 ≥ 30 → round up →
1:00 (since 12:43 rounds to 1 PM / 13:00, but in 12-hour format, we write 1:00)
Wait — important: The worksheet uses 12-hour format without AM/PM, so 12:43 rounds to
1:00
#### Problem 12: 02:39
Minutes = 39 ≥ 30 → round up →
3:00

Now let’s list all answers clearly:
1) 01:00 (given)
2) 5:00
3) 10:00
4) 12:00
5) 3:00
6) 10:00
7) 2:00
8) 6:00
9) 11:00
10) 4:00
11) 1:00
12) 3:00
I’ll double-check a few tricky ones:
- Problem 4: 11:50 → rounds to 12:00 ✔️
- Problem 6: 9:35 → rounds to 10:00 ✔️
- Problem 11: 12:43 → rounds to 1:00 ✔️ (not 12:00, because 43 > 30)
- Problem 12: 2:39 → rounds to 3:00 ✔️
All good.
Final Answer:
2) 05:00
3) 10:00
4) 12:00
5) 03:00
6) 10:00
7) 02:00
8) 06:00
9) 11:00
10) 04:00
11) 01:00
12) 03:00
Parent Tip: Review the logic above to help your child master the concept of time worksheet math is fun.
