Coordinates and Position

Grids are very useful tools when pinpointing a position.There are a few main

things about grids that you need to know first.

We use coordinates to help us to find an exact spot on a grid. They are made

up of two numbers – the first number will tell us the position horizontally and

the second number will tell us the position vertically.

This is a handy phrase to help you remember which way around the

coordinates are:

Along the corridor, then up the stairs’

So, for example, if we have the coordinate (4,9), it would mean that we need

to move 4 spaces along the x axis of the grid, then move upwards 9 boxes.

We can also have negative coordinates, which would mean moving from

right to left or downwards, depending on whether it is a horizontal or vertical

coordinate – we can draw negative y and x axes for these.

Lines on a grid

1. Lines which cross one another are called intersecting lines.

2. Lines which cross each other at a right angle are called

perpendicular lines.

3. Lines which are always the same distance apart and will

never cross are called parallel lines directions on a grid can

be given in the form of compass points.
