How game maps teach coordinates

Use grids, mini-maps and treasure markers to introduce x and y coordinates.

Quick answer

Game maps use a grid system with x and y coordinates to help players find their way around, locate items, and move characters. You can learn how to read these maps by understanding how the grid works and how to follow directions.

Learning outcome

By the end of this page, you will be able to use a grid map to find a location using x and y coordinates, and understand how maps help you navigate in games and real life. Success signs:
  • You can explain what x and y coordinates are
  • You can find a point on a grid using coordinates
  • You can use coordinates to give directions to a friend
  • You can see how maps help you find things in games

Why this matters

Coordinates are used in many games and real-life situations to help people find their way around. When you play games like Minecraft, Roblox, or even board games, you often use maps or grids to move your character or find treasure. Learning how to read coordinates helps you understand how to get from one place to another, whether it's in a video game or in real life, like when you're looking at a map to find a friend's house or a shop in town.

How it works

A game map is like a grid, with lines going across and up and down. The horizontal lines are called the x-axis, and the vertical lines are called the y-axis. When you want to find a point on the map, you need two numbers: one tells you how far across (x), and the other tells you how far up (y). For example, if you want to find the point (3, 5), you go 3 steps to the right and 5 steps up. The point where those two lines meet is your location.

Examples you can see

Let's imagine a simple game map with a grid. Each square on the grid is like a box you can move into. The grid starts at (0, 0) in the bottom left corner. If you're at the point (2, 3), you go 2 squares to the right and 3 squares up. You can draw this yourself on paper or use a game board to see it in action. Example 1: If a treasure is at (4, 2), you would move 4 steps to the right and 2 steps up from the bottom left corner to find it. Example 2: If your character starts at (1, 1) and needs to go to (5, 3), you would move 4 steps right and 2 steps up.

Try it as a mini adventure

Adventure: The Lost Treasure Hunt You are on a quest to find a treasure on a mysterious island. The treasure map shows the island with a grid. The treasure is hidden at the point (6, 4). Here's your journey:
  • Start at the bottom left corner (0, 0)
  • First, move 6 steps to the right
  • Then, move 4 steps up
  • At that point, you will find the treasure!
Try drawing your own map with a grid and place a few treasures at different coordinates. Ask a friend or family member to find them using the coordinates you give them.

Common mistakes

  • Mistake: Confusing the x and y coordinates. For example, thinking that (3, 5) means 3 steps up and 5 steps right.
    Why it happens: The order of numbers can be confusing.
    Fix: Remember that the first number is always x (right), and the second is y (up).
  • Mistake: Starting from the wrong corner of the grid.
    Why it happens: Not understanding that the grid starts at (0, 0) in the bottom left.
    Fix: Always start from the bottom left corner when reading coordinates.
  • Mistake: Counting the starting square as part of the steps.
    Why it happens: Not being careful with counting.
    Fix: Count only the steps you move, not the square you start on.

Parent and carer guide

To help your child learn about coordinates, try these simple steps:
  1. Draw a simple grid on paper or use a game board with a grid
  2. Start with simple coordinates like (1, 1), (2, 3), and (4, 2)
  3. Play a game where you give your child coordinates and they find the point
  4. Use everyday items like a map or a floor plan to show how coordinates work in real life
  5. Encourage your child to draw their own maps with coordinates and challenge others to find things
Remember, it's okay if your child gets confused at first. Coordinate systems take time to understand. Keep the practice fun and encouraging, and always praise their effort, not just their results.

Practice questions

  1. What are the coordinates of the point that is 2 steps right and 3 steps up?
  2. If a point is at (5, 1), how many steps right and up is it from the bottom left corner?

  4. Give the coordinates of the point that is 3 steps right and 2 steps up from the bottom left corner.
  5. What are the coordinates of the point that is 1 step right and 5 steps up?
Answers:
  1. (2, 3)
  2. 5 steps right, 1 step up
  3. 4 steps up
  4. (3, 2)
  5. (1, 5)

FAQ

What are coordinates in games?

Coordinates in games are numbers that help you find a specific place on a map. They tell you how far across (x) and how far up (y) to go.

Why do games use grids?

Games use grids to help players move their characters, find items, and understand where they are in the game world. Grids make it easier to plan moves and find things quickly.

Can I use coordinates in real life?

Yes! You can use coordinates when you use a map, find a seat in a cinema, or even when you're playing a board game. They help you find your way around.

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

The first number in a coordinate pair is always x (right), and the second is y (up). A helpful way to remember is: "X is across, Y is up."

What if I have a negative coordinate?

Negative coordinates mean you move in the opposite direction. For example, (-2, 3) means 2 steps left and 3 steps up. This is a bit more advanced, but it's part of how coordinates work in bigger games and maps.
