Time-travel maths quest: coordinates
A story-led junior maths adventure using clocks, calendars and ancient numbers to locate hidden items on grids and maps.
Quick answer
You can use coordinates to find secret locations on maps and grids, just like in a time-travel maths quest!
Learning outcome
By the end of this page, you will be able to find and describe positions on a grid using coordinates, like a time-travel explorer finding hidden treasures!
- You can say where a point is on a grid using an x and y number
- You can plot points on a grid using coordinates
- You can describe how to move from one point to another on a grid
- You can use coordinates to find secret items in a game or story
Why this matters
Coordinates are like a special language that helps us find exactly where things are. When you play games, look at maps, or even find your lost toy, you are using coordinates! Think about how a treasure map shows you where to dig, or how a football coach tells players where to stand. These are all examples of using coordinates to find locations. In a time-travel adventure, coordinates help you navigate through different time periods to find clues and treasures.
How it works
Coordinates are pairs of numbers that tell you exactly where something is on a grid. A grid is like a big piece of graph paper with rows and columns. The first number tells you how far across (left or right) to go. The second number tells you how far up or down to go.
- Look at the grid with rows and columns
- Find the x number (how far across)
- Find the y number (how far up or down)
- Write the coordinates as (x, y)
For example, if you want to find the point that is 3 spaces across and 2 spaces up, the coordinates are (3, 2).
Examples you can see
Let's imagine you are on a time-travel quest and need to find a hidden time capsule. The map shows a grid with numbers along the bottom and side. Here are some examples:
| Point | Coordinates | Location |
|---|---|---|
| A | (1, 3) | 1 space across, 3 spaces up |
| B | (4, 2) | 4 spaces across, 2 spaces up |
| C | (2, 5) | 2 spaces across, 5 spaces up |
| D | (5, 1) | 5 spaces across, 1 space up |
Try this: If you start at point A (1, 3) and want to get to point B (4, 2), how do you move? You go 3 spaces right and 1 space down.
Try it as a mini adventure
Imagine you are a time-travel explorer! You have a special map showing a grid of time zones. Your mission is to find three ancient clocks hidden in different time zones.
First, you must find the First Clock at coordinates (3, 4). Start at the bottom left of your grid and move 3 spaces to the right and 4 spaces up. What do you find there?
Next, you must locate the Second Clock at coordinates (6, 1). Move 6 spaces to the right and 1 space up. What do you discover?
Finally, you must find the Third Clock at coordinates (2, 7). Move 2 spaces to the right and 7 spaces up. What ancient timepiece do you uncover?
Draw your own time-travel grid and mark where you found each clock. You can even draw a treasure chest at the origin (0, 0) to show where you started your quest!
Common mistakes
- Mistake: Getting confused about which number is across and which is up.
Why it happens: The first number in coordinates is always across (x-axis), and the second is up (y-axis).
Fix: Remember "X is across, Y is up" or think of it like "X is for X-axis, Y is for Y-axis". - Mistake: Forgetting to write coordinates in the correct order (x, y).
Why it happens: Kids sometimes mix up the order when writing or reading coordinates.
Fix: Always say "first number across, second number up" when you write coordinates. - Mistake: Starting from the wrong corner of the grid.
Why it happens: Some people start from the top right instead of the bottom left.
Fix: Always start from the bottom left corner (0, 0) of the grid.
Parent and carer guide
Help your child explore coordinates with these simple steps:
- Start with a simple grid drawn on paper or a whiteboard
- Label the bottom and left edges with numbers
- Ask your child to find a point like (3, 2) by moving 3 spaces across and 2 spaces up
- Play a game where you give coordinates and your child finds the point
- Use everyday examples like a chess board or a shopping mall map
- Encourage drawing their own time-travel maps with coordinates
Remember: Don't worry if they make mistakes. They're learning! Just gently correct them and keep the fun going.
Practice questions
- What are the coordinates of the point that is 2 spaces across and 3 spaces up?
Answer: (2, 3) - Where is the point at coordinates (5, 1)?
Answer: 5 spaces across, 1 space up - If you start at (1, 2) and move 3 spaces right and 1 space up, what are your new coordinates?
Answer: (4, 3) - What point is 4 spaces across and 2 spaces up?
Answer: (4, 2) - Which point is at (0, 5)?
Answer: On the left side, 5 spaces up
FAQ
What are coordinates?
Coordinates are pairs of numbers that tell you exactly where something is on a grid. The first number shows how far across (left or right), and the second shows how far up or down.
How do I remember which number is which?
Think of "X is across, Y is up". Or remember that coordinates go in the order (x, y), just like the alphabet.
Can I use coordinates in real life?
Yes! Maps use coordinates to show locations, video games use them to move characters, and even your phone's GPS uses coordinates to find where you are.
What if I'm not good at math?
That's okay! Coordinates are just like learning a new language. With practice, you'll get better. Start with simple grids and work your way up.
How can I practice coordinates at home?
You can draw grids on paper, play treasure hunt games, or use online coordinate games. Try plotting points on a chess board or your own drawing!
