Units of Time and How They Relate

Learn how seconds, minutes, hours and days fit together as nested units of time. Explore the relationships between them and practise converting from one unit to another using a classroom clock.

Warning: Your screen size is quite small for viewing this. Rotate your device into landscape mode if you can.

1 - Getting Started ~4 mins

Key point

We are going to sit in complete silence for exactly one minute. Keep your eyes on the clock at the front of the room as the time goes by.

Illustration for Getting Started When the minute is up: how many seconds do you think passed? And how many of those quiet minutes would it take to fill one whole hour?

👇 Mark your steps as done as you complete them.

+5 XP

2 - Watch and Notice ~8 mins

Look at the clock. The second hand goes all the way around, a full 60, just to move the minute hand on by one notch. So 60 seconds make one minute.

Look at the minute hand. It goes the whole way around, 60 minutes, to complete one hour. And a whole day is 24 hours: the hour hand goes right around the clock twice. Then 7 of those days make one week.

Each bigger unit is built from a fixed number of the next smaller one.

👇 Mark your steps as done as you complete them.

+10 XP

3 - Try It Together ~10 mins

Key point

Today we drive the clock together to show the units nesting. First we sweep the minute hand once right around to make one whole hour. Then we move the hour hand on one notch to show that hour passing. After that we take the hour hand around twice to show one whole day. And 7 of those days would make one week.

Show one whole hour, then a day

4 - Build the Fact List in Your Copy ~3 mins

COPYBOOK MOMENT

In your maths copy, copy out and complete this fact list, filling in each blank:

1 minute = ___ seconds
1 hour = ___ minutes
1 day = ___ hours
1 week = ___ days

Then write one time fact of your own underneath.
