Coordinates & Graphs

Coordinates and graphs help us locate points on a grid and visualise relationships between numbers. These skills are essential for geometry, algebra, and 11+ problem solving.

📍 Coordinates are pairs of numbers that tell us the position of a point on a grid. They are written as (x, y), where x is the horizontal position and y is the vertical position.

Example: The point (2, 3) is 2 units across (right) and 3 units up.

📊 Graphs help us show how numbers are related. Common types of graphs include:

• Line graphs – show how values change over time.
• Bar charts – compare quantities visually.
• Scatter plots – show patterns or relationships between two sets of numbers.

Remember: "Along the corridor, then up the stairs" is a great way to remember to read the x-axis before the y-axis!

Tips:

• Always label your axes clearly.
• Check that each unit is equal on the grid.
• Plot points carefully and connect them if needed for line graphs.

Understanding coordinates and graphs allows you to visualise problems, find missing points, and interpret data for 11+ maths.
