What Are Coordinate Graphs?
Coordinate graphs help us locate points using numbers!
A coordinate graph has two number lines that cross each other. The horizontal line is called the x-axis, and the vertical line is called the y-axis. Together, they form the coordinate plane where we can plot points using ordered pairs like (3, 5).
How to Plot Points in 3 Easy Steps
1️⃣ Find the x-coordinate - Move right (positive) or left (negative) on the x-axis
2️⃣ Find the y-coordinate - Move up (positive) or down (negative) from there
3️⃣ Mark the spot - Where your x and y meet is your point!
Let's Practice Together!
Example 1: Treasure Hunt
Captain Mathbeard has hidden treasure at (4, 2) on the map below. Can you find it?
Remember: The first number is x (left/right), the second is y (up/down).
Example 2: Plot Your Own Point
Try plotting the point (5, 3) on this coordinate plane:

Parent Tips 🌟
- Make it a game: Turn coordinate graphing into a treasure hunt by hiding small treats at different (x,y) locations around your home.
- Connect to real life: Show how coordinates are used in maps, video games, and GPS navigation to make learning practical.
- Use graph paper: Have your child create simple drawings by plotting points and connecting them - great for practicing both coordinates and creativity!
