Understand Coordinate Grids

In this activity, you will be asked to describe and write coordinates on a positive and negative axis using a coordinate grid.

Remember, we always read along the corridor (the x-axis) and then up/ down the stairs (the y-axis).

Look at the point A...

Its x-coordinate is -5 on the x-axis.

Its y-coordinate is -3 on the y-axis.

The x number always comes before the y number.

We write the coordinates for A as (-5, -3)

Notice, we always write coordinates in brackets with a comma between the two numbers.

Using the rules above, check you can read each of the points of the parallelogram on the coordinate grid.

Remember, 'along the corridor and up/down the stairs'

You always write the x point before the y point.

Are you ready to have a go?
