Starting with positive coordinates
Plotting points is easier to learn without negative numbers, so most schools begin with the first quadrant only. The origin sits in the bottom-left corner, the x-axis runs along the bottom and the y-axis up the left side, both from 0 to 20. Numbers appear every two squares, so the grid stays uncluttered while every point is easy to find.
Activities
- Mystery pictures: give a list of points to plot and join in order; the shape appears as the last point is joined.
- Treasure maps: draw an island and hide treasure at a coordinate for a partner to find.
- Shapes: plot the corners of a rectangle and work out its perimeter and area by counting squares.
- Straight-line patterns: plot (1, 2), (2, 4), (3, 6) and predict the next point.
Moving on
Once pupils are confident, introduce negative numbers on a number line and then the four-quadrant coordinate plane. For free-form graphing on a full page, use coordinate plane graph paper.
Printing
Print at 100% / Actual size so squares stay equal in both directions; a stretched grid makes plotted shapes look distorted.

Frequently asked questions
What is the first quadrant?
The part of a coordinate plane where both x and y are positive or zero, the top-right quarter. Most curricula start plotting there before introducing negative coordinates.
How big are the squares?
On Letter with axes from 0 to 20, each square is roughly 9 mm. The 0 to 10 variation doubles that, which is easier for younger hands.
How do I plot a point?
Read the first number along the x-axis (across), then the second up the y-axis. For (6, 14), go six squares right and fourteen up. Remember: along the corridor, then up the stairs.
Where are the four-quadrant grids?
On the coordinate plane hub page, with axes from −10 to 10 and other ranges.
