Understanding the coordinate grid with x-axis (horizontal) and y-axis (vertical), and how to describe positions.
Where your child meets this in real life: Reading maps, understanding game boards like chess or battleships
This topic isn't tested on its own, but it sits inside questions on tested topics. Each SEAG paper has 28 maths questions. Questions 29 to 50 are multiple choice with five possible answers, and questions 51 to 56 need a short written answer. With 56 questions in 60 minutes across English and maths, that is about a minute per question.
SEAGReady breaks understand coordinate grids into 2 steps, taught in order so each skill builds on the last.
Identify the x-axis (horizontal), y-axis (vertical), and origin on a coordinate grid
Understand that positions are written as (x, y) where x is the horizontal value and y is the vertical value
Try three free questions from our understand coordinate grids course. They start easy and get harder, so you can see where your child's confidence runs out. If they manage the last one without a hint, this topic is probably secure. If not, the steps above show where to start.
Megan is learning to play Battleships. Her teacher explains that the grid has two axes. Which axis goes across horizontally?
Lewis is playing a grid game. He needs to move to position (5, 8). He says: 'I go 8 along and 5 up.' Is Lewis correct?
Reece is labelling an unlabelled coordinate grid using the standard mathematical convention. Which labelling is correct?
This is the exact interactive worked example your child sees in SEAGReady. Step through it and watch the method build up.
A coordinate grid has two axes that meet at the origin.
Which axis goes across horizontally, and which goes up vertically?
The horizontal line going across is the x-axis
Step 1 of 3
A coordinate grid has two axes that meet at the origin.
Which axis goes across horizontally, and which goes up vertically?
The x-axis goes across, y-axis goes up, they meet at the origin.
The key insight: Read the axes in coordinate order: horizontal x first, then vertical y.
Common mix-up: The y-axis goes across and the x-axis goes up. The standard convention labels the horizontal axis x and the vertical axis y.
These are the misconceptions we see most often in understand coordinate grids, including the ones our practice questions are specifically designed to catch.

SEAGReady finds the exact step where your child gets stuck, teaches it with worked examples like the one above, and brings it back for review so it sticks.
