Grade 3 Time Worksheet with Clocks and Time Conversion Exercises

Let's solve each question step by step from the worksheet.

1. Use “past” or “to” to tell the time

We need to describe the time using "past" or "to".
- "Past" means after the hour (e.g., 10 minutes past 3 = 3:10).
- "To" means before the next hour (e.g., 10 minutes to 4 = 3:50).

#### Clock 1:
- Hour hand is between 5 and 6.
- Minute hand is on 8 → 8 × 5 = 40 minutes.
- So, it’s 40 minutes past 5 → 40 minutes past 5
> ✔ Answer: 40 minutes past 5

#### Clock 2:
- Hour hand is between 8 and 9.
- Minute hand is on 4 → 4 × 5 = 20 minutes.
- So, it’s 20 minutes past 8 → 20 minutes past 8
> ✔ Answer: 20 minutes past 8

#### Clock 3:
- Hour hand is between 6 and 7.
- Minute hand is on 2 → 2 × 5 = 10 minutes.
- So, it’s 10 minutes past 6 → 10 minutes past 6
> ✔ Answer: 10 minutes past 6

2. Write the missing numbers

425 min = ____ h ____ min

We know:
- 1 hour = 60 minutes
- Divide 425 ÷ 60

→ 60 × 7 = 420 → 425 - 420 = 5

So, 425 minutes = 7 hours 5 minutes

> ✔ Answer: 7 h 5 min

3. Sophie learns Mathematics for 4h 30 min. Aidan learns for 2h 50 min. How much longer did Sophie learn than Aidan?

Subtract Aidan's time from Sophie's:

Sophie: 4h 30min
Aidan: 2h 50min

Since 30 min < 50 min, we borrow 1 hour from Sophie’s 4h → becomes 3h 90min

Now subtract:
- Hours: 3 - 2 = 1
- Minutes: 90 - 50 = 40

So, difference = 1 hour 40 minutes

> ✔ Answer: 1 hour 40 minutes

4. Wina sewed two blouses. It took 3h 40min for the first and 2h 55min for the second. She finished at 8:10 p.m. What time did she start sewing? (Use a timeline)

Total time spent:
- 3h 40min + 2h 55min

Add:
- 3h + 2h = 5h
- 40min + 55min = 95min → 95 min = 1h 35min

So total = 5h + 1h 35min = 6h 35min

She finished at 8:10 p.m., so subtract 6h 35min from 8:10 p.m.

Let’s do it step by step:

Start from 8:10 p.m.
Subtract 6 hours → 2:10 p.m.
Now subtract 35 minutes → 2:10 p.m. - 35 min = 1:35 p.m.

> ✔ Answer: 1:35 p.m.

5. Write the missing numbers

#### a. 396 years = ___ centuries ___ years
- 1 century = 100 years
- 396 ÷ 100 = 3 centuries with remainder 96 years

> ✔ Answer: 3 centuries 96 years

#### b. 72 months = _____ years
- 1 year = 12 months
- 72 ÷ 12 = 6

> ✔ Answer: 6 years

#### c. 49 days = _____ weeks
- 1 week = 7 days
- 49 ÷ 7 = 7

> ✔ Answer: 7 weeks

#### d. 51 days = _____ weeks _____ days
- 51 ÷ 7 = 7 weeks (7×7=49), remainder 2 days

> ✔ Answer: 7 weeks 2 days

#### e. 63 days = _____ weeks _____ days
- 63 ÷ 7 = 9 weeks exactly

> ✔ Answer: 9 weeks 0 days
