11+ Maths: Using Coordinates: Including Coordinate Graphs (GL & CEM style)
19 October 2026
Understanding coordinates
Coordinates help children describe exact positions on a grid, a skill often tested in 11+ maths. Each point is written as (x, y), showing how far along and up to move from the origin.
The axes and the origin
The horizontal axis is called the x-axis, and the vertical axis is the y-axis. Where they cross is the origin, marked as (0, 0). Always start reading or plotting from this point.
Plotting and reading points
To plot a point like (3, 2), move three steps right along the x-axis, then two steps up the y-axis. For negative numbers, move left or down. Remind your child: along the corridor, then up the stairs.
What to expect in 11+ questions
GL and CEM questions may ask children to identify coordinates, plot points, reflect or translate shapes, or find midpoints. Sometimes, children need to complete a shape when given some of its vertices.
Supporting your child at home
Encourage regular practice with grids, both drawing points and reading them. Check that axes are labelled and the scale is clear. Talk through each step calmly, especially the order of x then y.
Key insight: Consistent, calm practice with coordinates builds confidence and helps children tackle a wide range of 11+ maths questions involving graphs.
