Simplifying fractions

Follow this link to a page which explains how to simplify fractions.
(Use the questions at the bottom of the page to practise.)

Practice Tests

Here are two online practice tests - they are very similar to the ones you will be doing.

Level 1

Level 2

Miscellaneous interesting but probably not relevant stuff

How many times do you need to fold a piece of paper until it is thick enough to reach the moon?

Formula

This link explains how we substitute values into formulae.  (and includes some test questions)

And this explains why we use formulae.


Remember:
x² = x time x
x³ = x times x times x

but:

2x = 2 times x
3x = 3 times x

Collecting and displaying data

This link explains how you might take a survey.

This link suggests ways of displaying data collected in a survey.

And this tool allows you to make your own graphs!

Probability

Everything you need to know is here:

There are some questions at the bottom of the page. Do try them. They are more difficult than you will need for Level 2
There is also a link to activities involving rolling dice. Do try these activities if you have time. 

Finding fractions of a number

For both levels 1 and 2, all you'll have to do with fractions is find fractions of a number.

For example, you may be asked to find 1/4 of something.

To do this, simply divide by 4.

Or you might be asked to find 2/5 of something.

To do this, divide by 5 then times by 2.

In short:

To find a fraction of a number, divide by the bottom number and multiply by the top number.

And that's it!
