Airport maths quest: coordinates
A story-led junior maths adventure using departures, luggage weights and route maps to locate hidden items on grids and maps.
Quick answer
You can use coordinates to find exact locations on a grid or map, like finding a hidden treasure in an airport or locating a lost suitcase.
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 pilots and airport staff use them to guide planes and find luggage.
Success signs:
- You can read and write coordinates like (3, 5)
- You can plot points on a grid using coordinates
- You can find hidden items using grid coordinates
- You can describe where things are using grid positions
Why this matters
Coordinates are used everywhere! In airports, they help pilots land planes safely. In games, they help characters move around. In maps, they help you find your way. Understanding coordinates helps you solve puzzles, play games, and even find your lost toy in the house!
How it works
Coordinates are two numbers that tell you exactly where something is on a grid. The first number is the horizontal position (left or right), and the second number is the vertical position (up or down).
Think of it like a treasure map. You need two clues to find the treasure:
- How many steps to the right?
- How many steps up?
We write coordinates like this: (horizontal, vertical)
For example, (4, 2) means 4 steps to the right and 2 steps up.
Examples you can see
Let's imagine you're at the airport and need to find your luggage. The airport has a big map with a grid. Here's how it works:
| Grid Position | Coordinates | What's Here |
|---|---|---|
| Top left corner | (1, 5) | Lost luggage bin |
| Center of map | (3, 3) | Information desk |
| Bottom right corner | (5, 1) | Restaurants |
Imagine you're looking for a suitcase that's at position (2, 4). Here's how you'd find it:
- Start at the bottom left corner
- Move 2 steps to the right (along the bottom row)
- Move 4 steps up (along the side column)
- You'll find the suitcase at position (2, 4)
Let's try another example with a smaller grid:
Grid:
| 1 | 2 | 3 | 4 | |
|---|---|---|---|---|
| 1 | A | B | C | D |
| 2 | E | F | G | H |
| 3 | I | J | K | L |
| 4 | M | N | O | P |
Find the position of letter K:
- Letter K is in the third row from the top
- Letter K is in the third column from the left
- So K is at coordinates (3, 3)
Try it as a mini adventure
Adventure: The Airport Treasure Hunt
You're at the airport with your family. The airport has a big treasure map! Your task is to find the hidden treasure using coordinates.
Here's your treasure map:
| Position | Coordinates | Hidden Item |
|---|---|---|
| 1st item | (1, 2) | Toy airplane |
| 2nd item | (3, 4) | Sticker book |
| 3rd item | (5, 1) | Chocolate bar |
| 4th item | (2, 3) | Coloring pencils |
Now, let's go on a treasure hunt!
- Start at the bottom left corner of the map
- Find the first treasure at (1, 2)
- Then go to (3, 4) for the second treasure
- Next, go to (5, 1) for the third treasure
- Finally, go to (2, 3) for the last treasure
Can you draw a map of your airport treasure hunt? Mark where each treasure is and write the coordinates!
Common mistakes
- Mistake: Mixing up the order of coordinates
Why it happens: Children often confuse which number goes first
Fix: Remember: horizontal first, then vertical - "H-V" or "Right then Up" - Mistake: Starting from the wrong corner
Why it happens: Not understanding that we start from the bottom left
Fix: Always start from the bottom left corner of the grid - Mistake: Counting the starting position as "1"
Why it happens: Confusing the counting method with the grid system
Fix: Count the steps from the starting point, not including the starting point itself - Mistake: Forgetting to write coordinates in brackets
Why it happens: Not understanding that coordinates are a pair of numbers
Fix: Always write coordinates as (number, number) with brackets
Parent and carer guide
Helping your child learn coordinates is like playing a fun game! Here are 5 ways to support learning:
- Play treasure hunts at home: Create a grid on paper with your child and hide small toys. Give them coordinates to find them.
- Use real maps: Look at a map of your local area together and practice finding locations using coordinates.
- Count steps together: When walking to the park, count steps right and then up to reach a specific spot.
- Draw grids: Draw a simple 3x3 grid and practice writing coordinates for different points.
- Practice with games: Many board games use grid coordinates. Try playing with your child and talking about positions.
Remember: It's okay if your child makes mistakes. These are learning opportunities. Celebrate progress, not just perfect answers!
Practice questions
- What are the coordinates for a point that is 2 steps to the right and 3 steps up?
- Where is point (4, 1) located on a grid?
- Plot point (2, 3) on a grid
- What coordinates would you use to find a point that is 5 steps to the right and 2 steps up?
- Draw a 4x4 grid and mark the point (3, 2)
Answers:
- Coordinates are (2, 3)
- Point (4, 1) is 4 steps to the right and 1 step up
- Plot point (2, 3) - 2 steps right, 3 steps up
- Coordinates are (5, 2)
- Draw a 4x4 grid and mark point (3, 2)
FAQ
What are coordinates?
Coordinates are two numbers that tell you exactly where something is on a grid. The first number shows how far right or left, and the second number shows how far up or down.
Why do we need coordinates?
Coordinates help us find exact locations quickly and easily. They're used in maps, games, science, and even in airports to find luggage and guide planes.
How do I remember which number goes first?
Think of it like the alphabet: "horizontal first, then vertical". You can remember "H-V" or "Right then Up".
Can I use coordinates with letters?
Yes! You can use coordinates to find letters on a grid. For example, (2, 3) might be the letter "K" in a grid of letters.
What if I'm not good at coordinates?
That's okay! Coordinates take practice. Start with simple grids and work your way up. Every mistake helps you learn better!
