11 plus practice using coordinate grids: supporting your child
26 October 2026
Understanding coordinate grids
Coordinate grids are a key part of 11+ maths, especially in GL and CEM style exams. Children need to read, plot and interpret points using coordinates. This skill is often tested in questions about shapes, movement and position.
How coordinates work
A coordinate grid has a horizontal (x) axis and a vertical (y) axis. Each point is described by two numbers in brackets, like (3, 5). The first number tells you how far across, and the second tells you how far up.
Key insight: Always read coordinates as (across, then up)
Remind your child to go across first, then up. This helps avoid one of the most common mistakes in coordinate questions.
Worked example: plotting points on a grid
Step 1: Read the question. It asks you to plot the points (2, 1), (2, 4), (5, 1) and (5, 4) on a coordinate grid.
Step 2: Start with (2, 1). Move 2 squares across from the origin (0, 0), then 1 square up. Mark the point.
Step 3: Plot (2, 4). From the origin, go 2 across and 4 up. Mark this point.
Step 4: Plot (5, 1). Move 5 across and 1 up from the origin. Mark the point.
Step 5: Plot (5, 4). Go 5 across and 4 up from the origin. Mark the final point.
The correct answer is that these four points form the corners of a rectangle on the grid.
Using grids to find missing points
11+ questions may ask for the missing corner of a shape, or to find the midpoint between two points. Encourage your child to look for patterns in the numbers, such as which coordinates stay the same and which change.
Practice tips for parents
Let your child practise with blank grids. Ask them to plot points, draw shapes, and describe positions. Try simple compass directions too, such as "move 3 up and 2 right from (1, 1)".
Building confidence with coordinate questions
Regular practice helps children recognise patterns and avoid common mistakes. Confidence grows as they become familiar with the layout and logic of coordinate grids.
