Students extend the coordinate grid in every direction — using negative numbers to plot points in all four quadrants — and learn to name which quadrant a point lands in.
Students will be able to…
The coordinate plane doesn’t stop at zero — it keeps going left and down with negative numbers. How do you plot a point like (−2, 3)?
Project this and have students plot each point — including negatives. The tool names the quadrant and explains the directions.
A point (x, y): x tells you left/right, y tells you up/down.
Tap any phase to open the teacher moves and student actions.
How do you reach (−2, 3) — which way is negative?

Aligned to the Common Core State Standards for Mathematics, including the Standards for Mathematical Practice.
Understand signs of numbers in ordered pairs as indicating locations in quadrants.
Find and position ordered pairs on a coordinate plane.
Solve problems by graphing points in all four quadrants.
Draw polygons in the coordinate plane given coordinates.

Have students plot a point, then plot its reflection across the x-axis and the y-axis, and describe how the signs change. A printable four-quadrant grid is in the Math library.
Tap a card to flip it, then rate whether you knew it. Built from this lesson’s vocabulary.
