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
SEAGReady breaks understand coordinate grids into 2 steps, taught in order so each skill builds on the last.
supporting lesson — excluded from official-format mocks
Identify the x-axis (horizontal), y-axis (vertical), and origin on a coordinate grid
supporting lesson — excluded from official-format mocks
Understand that positions are written as (x, y) where x is the horizontal value and y is the vertical value
Three free sample questions from our understand coordinate grids course. Every question comes with a full explanation, and hints that guide without giving the answer away.
Megan is learning to play Battleships. Her teacher explains that the grid has two axes. Which axis goes across horizontally?
Orla is reading the coordinates (3, 5). Which number tells her how far up to go?
George is looking at a coordinate grid in his maths book. Which axis goes up and down vertically?
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.
