You know, just because numbers say 'how many?' of something

and don't tell you what the things are,

doesn't mean that numbers can't tell you lots more about things than

simply how many of them there are.

You can use numbers to tell you about the shape of things and how much space they take up.

You just have to know the shape of things, and numbers can tell you a lot about them.

But it's useful to know the names of different shapes

so other people know what you are talking about,

and then you can compare things using numbers.

You may know that the shape of a page from a book is called a rectangle,

and see that a door is the same shape,

but numbers can tell you just how much one is bigger than another.

And some shapes fit together to make patterns,

and some shapes fit together to make objects,

and it is said that shapes that are flat have only two dimensions,

usually called 2D for short,

and shapes that make objects have three dimensions,

otherwise known as 3D.

And shapes are described by the number of sides that they have,

and the angles that they have between them.

We measure angles by how much a line moves in a circle around a point.

And we have a way of measuring those angles using numbers, a bit like the numbers of the minutes around the face of a clock.

We use numbers to divide up the circle,

and like the circle of a compass we can use them to know which way we are facing.

And that is really useful if you want to get from somewhere to somewhere else.

It means that if you know where you are you can know which way you need to go,

if you know the angle you need to take to get where you are going.

And of course, when muslims are making their Salah, they need to know the angle they must face if they are to face their Qibla,

when they all stand in line facing the Cube that is the Kaabah in Makkah.
