# Free Y6 maths worksheets: Large numbers

A couple of free maths worksheets for older children in primary school. They will need to have a good idea of time, a calculator handy and a pretty good mathematical brain to answer these questions. There is usually more than one way to tackle problems such as these and it is worthwhile discussing with your child why they are taking a particular approach.

Take the question “Is 100 000 seconds more than a day?”

Most people would not know this off-hand but it can be worked out easily.

Divide by 100 000 by 60 to get the number of minutes. (You may get recurring decimals.)

Divide the answer by 60 to get the number of hours.

Or:

take 24 hours and multiply by 60 to get the number of miutes then multiply by 60 again to get the number of seconds a nd compare. Much easier to do this with a calculator – it is the ptoblem which involves the maths rather than slogging through multiplication and division on paper – so use a calculator!
