Knight maths quest: coordinates
A story-led junior maths adventure using quests, shields and tournament scores to locate hidden items on grids and maps.
Quick answer
You can find hidden items in a knight's quest by using coordinates - pairs of numbers that tell you exactly where to look on a grid. Coordinates help you find the treasure, locate your shield, or discover the secret map!
Learning outcome
By the end of this page, you will be able to use coordinates to locate items on a grid, and understand that coordinates are written as (x, y) where x tells you how far across and y tells you how far up.
- You can read and write coordinates like (3, 5)
- You can find coordinates on a grid
- You can use coordinates to solve a quest or puzzle
- You can explain how coordinates help you find things in real life
Why this matters
Coordinates are like a secret code that helps knights, explorers, and even you find exactly where things are! When you're playing a game, looking at a map, or planning where to build your LEGO castle, coordinates help you know exactly where to go. They're used in GPS, video games, and even in science and engineering. Learning coordinates helps you become a super detective!
How it works
Coordinates work like a set of directions on a grid. Every point on a grid has two numbers:
- The first number (x) tells you how far across from the left
- The second number (y) tells you how far up from the bottom
For example, if you see the coordinate (4, 3), you go 4 steps to the right and 3 steps up.
Examples you can see
Imagine you're on a quest to find a hidden treasure in a castle. The map shows a grid, and the treasure is at coordinate (5, 2). Here's how to find it:
- Start at the bottom left corner (0, 0)
- Move 5 steps to the right (that's the x-axis)
- Move 2 steps up (that's the y-axis)
- You're at the treasure!
Let's try another one: Find the shield at coordinate (2, 6).
- Start at (0, 0)
- Move 2 steps right
- Move 6 steps up
- You found the shield!
Here's a grid with some points marked:
| Y-axis | 0 | 1 | 2 | 3 | 4 |
|---|---|---|---|---|---|
| 0 | (0,0) | (1,0) | (2,0) | (3,0) | (4,0) |
| 1 | (0,1) | (1,1) | (2,1) | (3,1) | (4,1) |
| 2 | (0,2) | (1,2) | (2,2) | (3,2) | (4,2) |
| 3 | (0,3) | (1,3) | (2,3) | (3,3) | (4,3) |
| 4 | (0,4) | (1,4) | (2,4) | (3,4) | (4,4) |
Notice how each point is written as (x, y). The first number is the x-coordinate, and the second is the y-coordinate.
Try it as a mini adventure
Join Sir Mathilda on her quest to find the lost Dragon's Crown! Here's your map with clues:
- Clue 1: The crown is at (3, 4)
- Clue 2: The shield is at (1, 2)
- Clue 3: The magic potion is at (5, 1)
Your mission: Find each item on this grid:
| Y-axis | 0 | 1 | 2 | 3 | 4 | 5 |
|---|---|---|---|---|---|---|
| 0 | ? | ? | ? | ? | ? | ? |
| 1 | ? | ? | ? | ? | ? | ? |
| 2 | ? | ? | ? | ? | ? | ? |
| 3 | ? | ? | ? | ? | ? | ? |
| 4 | ? | ? | ? | ? | ? | ? |
| 5 | ? | ? | ? | ? | ? | ? |
4th time: Find the crown at (3, 4) - move 3 steps right and 4 steps up
6th time: Find the shield at (1, 2) - move 1 step right and 2 steps up
8th time: Find the potion at (5, 1) - move 5 steps right and 1 step up
Common mistakes
- Mistake: Confusing x and y coordinates
- Why it happens: When you're moving, it's easy to forget which direction is which
- Fix: Remember: "across first, then up" or "x is across, y is up"
- Mistake: Writing coordinates in the wrong order
- Why it happens: Kids often think the first number is up and the second is across
- Fix: Always remember: (x, y) = (across, up)
- Mistake: Starting from the wrong corner
- Why it happens: Some children start from the top or the right instead of the bottom left
- Fix: Always start at (0, 0) which is the bottom left corner
Parent and carer guide
Help your child practice coordinates with these simple steps:
- Draw a small grid on paper and label the axes
- Give your child coordinates and ask them to mark the point
- Play a game where you hide objects and give coordinates to find them
- Use a treasure hunt at home with simple coordinates
- Point out real-life examples like maps or games that use coordinates
Watch for these signs that your child understands:
- They can correctly identify (x, y) coordinates
- They can find items using coordinates
- They can explain what x and y mean
- They can make up their own coordinates
Don't worry if they get confused at first - it takes practice!

FAQ
What are coordinates used for?
Coordinates are used to find exact locations on maps, games, and charts. They help you find your way around, locate items, and plan where to build or place things.
Can I use coordinates with any grid?
Yes! You can use coordinates on any grid, whether it's a map, a game board, or a simple drawing. The key is that the grid has clear x and y axes.
How do I remember which number is which?
Remember: "across first, then up" or "x is across, y is up". You can also think of it like "x is the first letter, so it's the first number" and "y is the second letter, so it's the second number".
Do coordinates work in real life?
Yes! GPS systems, maps, and even games like Battleship use coordinates. When you're looking at a football pitch or a chess board, you're using coordinates!
What comes after learning coordinates?
After coordinates, children often learn about graphs, shapes, and more complex maths like algebra. Coordinates are a great foundation for understanding how to plot and read graphs.
