By the time they reach Year Six, students of KS2 Maths should be competent with all aspects of time. They will know the values of different units of time, from the number of seconds in a minute to the number of years in a decade, century or millennium. Consequently they will be able to choose suitable units for measuring time in varying circumstances. Year Six children should also be able to write and tell the time on 24 hour and 12 hour digital and analogue clocks.
Years, decades and even a century  these are the larger measurements of time. There is an even bigger one, a millennium. If someone lives for over a century, they have had what's known as 'a good innings' which is a cricketing term. If someone tells you they have lived for over a millennium, they are lying!
Do you know how many years are in a decade, a century or a millennium? Take this test and find out what you know about time.

Most oak trees live to be about 200 years old

That's a slow and relaxed pace  but 30 hours would be a crawl and 30 seconds would be as fast as a racing car!


To work out the hour on a 24 hour clock just count on from 12

00:55 would be five to one in the morning


Greenwich is in London so the time for all of Britain is the same as Greenwich Mean Time

15 + 9 = 24 but 24:00 is displayed as 00:00 on a 24 hour clock
