**Coordinates** describe the position of a specific **point **on a grid or graph.

They are written as a bracket with a pair of numbers separated with a comma **e.g. (4, 6)**.

The first number is called the **x-coordinate**. We find it on the **horizontal** axis.

The second number is called the** y-coordinate**. We find it on the **vertical** axis.

On the grid below, a point at **(2, 4) **is shown.

We need to go 2 across and then 4 up to mark the correct point:

A special point on the coordinate grid is the **origin**.

This is the point with coordinates **(0, 0)**.

The x- and the y-axis cross at the **origin**.

In this activity, we will identify and work with the coordinates of points involving positive values for x and y.

You may want to have a sheet of squared paper handy, so that you can draw and map out coordinates on your own grid to help you with this activity.
