Fairground maths quest: coordinates

A story-led junior maths adventure using rides, tickets and chance games to locate hidden items on grids and maps.

Quick answer

Coordinates help us find exact places on a grid, like finding your seat at a fairground or locating a hidden treasure!

Learning outcome

By the end of this page, you will be able to use coordinates to locate and describe positions on a grid, just like finding rides and games at a fairground. Success signs:
  • You can say where something is on a grid using "x" and "y" numbers
  • You can plot points on a grid using coordinates
  • You can find hidden items using clues given as coordinates
  • You can describe your position on a fairground map

Why this matters

Coordinates are used everywhere in real life! When you play a board game, you use coordinates to move your piece. When you go to a fairground, you use coordinates to find your way around. Even in video games, characters move using coordinates. Understanding coordinates helps you navigate, solve puzzles, and find your way around maps and games.

How it works

Coordinates are like a special address for places on a grid. Every point on a grid has two numbers:
  • The x-coordinate tells you how far across (left or right) to go
  • The y-coordinate tells you how far up or down to go
The coordinates are written as (x, y) - like a pair of numbers in brackets. The first number is always x, the second is always y. Let's imagine a fairground map with a grid. The bottom left corner is (0,0). To find a ride at (3,2), you go 3 steps to the right and 2 steps up.

Examples you can see

Let's go on a fairground adventure together! Example 1: The Ferris Wheel At the fairground, the Ferris wheel is at position (5, 3). This means:
  • 5 steps to the right from the starting point
  • 3 steps up from the starting point
Example 2: The Candy Shop The candy shop is at (2, 4). So you go:
  • 2 steps to the right
  • 4 steps up
Example 3: The Game Tent The game tent is at (7, 1). That means:
  • 7 steps to the right
  • 1 step up
Example 4: The Treasure Hunt You're looking for a treasure at (4, 6). You need to:
  • Go 4 steps right
  • Go 6 steps up

Try it as a mini adventure

Adventure: The Fairground Treasure Hunt! You're going on a treasure hunt at the fairground. Here are your clues: Clue 1: The treasure is hidden at (3, 5) Clue 2: The ticket booth is at (6, 2) Clue 3: The roller coaster is at (1, 7) Clue 4: The cotton candy stand is at (8, 4) Your mission: 1st time: Start at (0, 0) - the entrance 2nd time: Go to the ticket booth at (6, 2) 3rd time: Go to the roller coaster at (1, 7) 4th time: Go to the cotton candy stand at (8, 4) 5th time: Find the treasure at (3, 5) Challenge: Draw your own fairground map with at least 5 rides or attractions. Label each one with its coordinates. Can you make a treasure hunt for a friend?

Common mistakes

  • Mistake: Confusing x and y coordinates Why it happens: When you're learning, it's easy to mix up which number is which Fix: Remember "x is across, y is up" or "x is x-ray, y is yawn"
  • Mistake: Starting from the wrong corner Why it happens: The grid might start at a different point Fix: Always check where (0, 0) is on your grid
  • Mistake: Forgetting to write coordinates in brackets Why it happens: Writing numbers without the correct format Fix: Always write coordinates as (x, y) with brackets
  • Mistake: Going the wrong direction Why it happens: Confusing left/right with up/down Fix: Practice with a grid and move carefully in the right directions

Parent and carer guide

How to help your child:
  • Start with simple grids using just positive numbers (0-5)
  • Use a real fairground map or draw one together
  • Play coordinate games like "I Spy" using coordinates
  • Practice by drawing a simple grid and placing items at different coordinates
  • Ask your child to explain how they found something using coordinates
  • Encourage them to create their own fairground maps
  • Use everyday situations: "Where is your bedroom in the house?" (like coordinates)
What to watch for:
  • They might get confused about which number is x and which is y
  • They might forget to count from (0, 0)
  • They might make small counting errors
  • They might not understand that coordinates are always written (x, y)
What not to worry about:
  • It's normal to make small mistakes when learning
  • Coordinate skills take time to develop
  • They might need to practice with visual aids first
  • They'll get better with more practice

Practice questions

  1. Where is the carousel if it's at (4, 3)?
  2. What are the coordinates of the ice cream van if it's 2 steps right and 5 steps up?
  3. Find the swings at (6, 1). How many steps right and up did you take?
  4. What is the position of the petting zoo at (2, 7)?
  5. Where would you go to find the ring toss game at (8, 2)?
Answers:
  1. 4 steps right and 3 steps up
  2. (2, 5)
  3. 6 steps right and 1 step up
  4. 2 steps right and 7 steps up
  5. 8 steps right and 2 steps up

FAQ

What are coordinates used for?

Coordinates are used to find exact places on a map or grid. They help us navigate, play games, and solve puzzles. You use them when you play board games, use a map, or play video games.

How do I remember which number is x and which is y?

Think of it like this: "x is across, y is up". Another way is to remember that "x" is like the "x" in "x-ray" (horizontal), and "y" is like the "y" in "yawn" (vertical).

Do I always start at (0, 0)?

Not always! The starting point depends on the grid. Sometimes (0, 0) is at the bottom left, but it can be anywhere. Always check where the grid starts before you begin.

Can I use coordinates with negative numbers?

Yes! You can use negative coordinates too. Negative numbers mean you go left or down. For example, (-3, 2) means 3 steps left and 2 steps up.

How can I practice coordinates at home?

You can practice by drawing grids, placing objects at coordinates, or playing coordinate games. Try making a treasure hunt with your family using coordinates to find hidden items.
