Time Estimation Practice Worksheet

Help Sienna and Kai plan a picnic by estimating how long each activity takes. Choose a sensible estimate, then solve the time puzzles. A timer is optional for the investigation.

Make a sensible estimate

Choose the most reasonable time for each activity.

1.Sienna brushes her teeth before leaving. About how long might this take?

30 seconds
2 minutes
20 minutes

2.Kai claps 20 times. Which is a sensible estimate?

10 seconds
1 minute
10 minutes

3.They walk from the picnic rug to a nearby tree and back. About how long might the walk take?

15 seconds
15 minutes
2 hours

Read the picnic clock

The clock shows when the friends start packing. Use the packing time to work out when they finish.

4.At 10:00, Sienna starts packing. Draw the minute hand to show 10:00 on the clock.

5.Packing takes about 5 minutes. What time might the friends finish?

6.Which is longer: 3 minutes or 150 seconds? Explain how you know.

Time detective challenge

Use the number line to compare the lengths of three picnic jobs. Each mark is 1 minute.

7.The jobs take 3 minutes to fill a drink bottle, 5 minutes to pack fruit, and 8 minutes to walk to the picnic spot. Which job takes the longest?

8.How much longer does the walk take than filling the bottle?

9.Put these activities in order from shortest to longest: pack fruit (5 minutes), fill a drink bottle (3 minutes), walk to the picnic spot (8 minutes).

10.Choose one everyday activity. Estimate how long it takes and name a time unit (seconds or minutes). Then explain why your estimate seems sensible.
