Space explorer maths quest: coordinates
A story-led junior maths adventure using rockets, planets and alien signals to locate hidden items on grids and maps.
Quick answer
Coordinates are pairs of numbers that help us find places on a grid or map – like telling a spaceship where to land or where to find a hidden treasure!Learning outcome
By the end of this page, you will be able to use coordinates to find locations on a grid and describe where things are in space. Success signs:- You can say which numbers come first and second in a coordinate pair
- You can find a point on a grid using two numbers
- You can describe where something is using coordinates
- You can play a game using coordinates to find hidden items
Why this matters
Coordinates are like secret codes that help us find our way around. In space, astronauts use coordinates to navigate their ships and land on planets. When you play games on a computer or tablet, coordinates help the characters move around the screen. Even when you're looking for your lost toy in the house, you're using coordinates in your head – "it's in the corner by the window". Coordinates are everywhere, and learning them helps you understand maps, games, and how to find your way around.How it works
Coordinates work like a pair of directions. The first number tells you how far to go along the horizontal line (called the x-axis), and the second number tells you how far to go along the vertical line (called the y-axis). You can think of it like a treasure map where you must follow two clues to find something hidden. Let's imagine you're on a space mission. You have a map of a planet, and you need to find a hidden alien signal. The map has a grid, and the signal is at point (3, 5). That means:- Move 3 spaces to the right along the bottom line
- Then move 5 spaces up along the side line
Examples you can see
Let's explore how coordinates work with some fun examples: Example 1: A Space Mission Imagine you're on a mission to explore Mars. Your spaceship's map shows a grid with coordinates. You find a message at point (4, 2). This means:- Go 4 steps to the right (along the bottom line)
- Go 2 steps up (along the side line)
- Move 7 steps to the right
- Move 3 steps up
- Move 5 steps along the horizontal axis
- Move 8 steps along the vertical axis
Try it as a mini adventure
Space Explorer Quest: Find the Alien Signal! You are a space explorer on a mission to find a hidden alien signal on a space station. The signal is at coordinates (6, 4). Here's your adventure:- Start at the bottom-left corner of your space station map
- First, move 6 steps to the right along the bottom line
- Then, move 4 steps up along the side line
- What do you find at that spot?
- Draw a grid on paper with 10 spaces on each side
- Choose a spot and tell your family its coordinates
- Have them find it using the clues
Common mistakes
- Mistake: Confusing the order of numbers in coordinates
Why it happens: Children may think the second number comes first or forget which direction to go
Fix: Practice saying "first go right, then go up" or use the phrase "across the garden, up the tree" - Mistake: Thinking that coordinates always start at 0, 0
Why it happens: Children might not understand that any point can be a starting point
Fix: Explain that the bottom-left corner is the starting point, but the numbers can be any size - Mistake: Not counting the starting point
Why it happens: Children may count the starting point as "1" instead of "0"
Fix: Practice counting steps, not the starting point - Mistake: Mixing up the horizontal and vertical directions
Why it happens: Children might not understand that the first number is always horizontal
Fix: Use visual cues like "across the room" for horizontal and "up the wall" for vertical
Parent and carer guide
- What to say: "Can you find the point (3, 5) on your grid?" or "Where would you put the alien ship at (8, 2)?"
- How to help: Use a grid paper or a grid drawn on the floor with tape. Let your child move along the grid using the coordinates.
- What to watch for: Do they mix up the order of numbers? Do they forget to count steps?
- How to make it fun: Create a treasure hunt using coordinates or play a game with a space station map
- What not to worry about: It's normal for children to make mistakes at first. Encourage them to try again and explain the correct way
Practice questions

FAQ
What are coordinates used for?
Coordinates are used to find exact locations on a map or grid. They're used in space missions, games, maps, and even in your everyday life when you're looking for something in a room.
How do I remember which number is which?
Think of it like a sentence: "Go across first, then go up." The first number is always across (horizontal), and the second number is always up (vertical).
Can coordinates be negative?
Yes, in advanced maths, coordinates can be negative, but for now, we'll use only positive numbers. This makes it easier to start with.
Are coordinates the same as directions?
Coordinates are a way to give directions to a specific point. They're more precise than just saying "go left" or "go up."
How can I practice coordinates at home?
You can practice by drawing grids on paper, using a floor grid with tape, or playing games where you find hidden objects using coordinates.
