Read points and plot your own on a −5 to +5 grid. Learn the four quadrants, the meaning of (x, y) and how negative coordinates work — with instant feedback and 5-question rounds. All on your device.
The four quadrants
Coordinates are written (x, y) — along the corridor (x), then up the stairs (y).
• Q1 (+, +) top-right · Q2 (−, +) top-left · Q3 (−, −) bottom-left · Q4 (+, −) bottom-right.
• On the axes themselves, one coordinate is 0.
• (2, 3) and (3, 2) are different points — order matters!
