In this activity, we will be learning how to work out how to use estimates and rounding when calculating times.
In real life, it is very useful to be able to work out roughly how long it takes for something to happen, or the actual time when something will take place. Often, an estimated time is useful because units of time like minutes are relatively short.
Remember that there are 60 minutes in an hour.
Half an hour is 30 minutes.
A quarter of an hour is 15 minutes.
In this activity, it will help to round times to the nearest whole, half or quarter or an hour.
5:06 is closer to 5 o'clock than to quarter past 5.
5:28 is nearly half past 5, or 5:30.
Let's try some examples, so you know how to approach this activity
Now we've tried these examples you should be ready to try some similar questions by yourself. Good luck!
