Coordinate Plane Navigator
x first, then y
Move across a four-quadrant grid. Ordered pairs become movement instructions.
What this game shows · The Coordinate Plane
The coordinate plane is two perpendicular number lines. Every ordered pair (x, y) is a unique address: the first number says how far across, the second says how far up. Negative numbers extend the address into all four quadrants.
- x-axis
- horizontal number line. Positive right, negative left.
- y-axis
- vertical number line. Positive up, negative down.
- Quadrant
- one of the four regions: I (++), II (−+), III (−−), IV (+−).
Aligned with CCSS 6.NS.C.6 (graph points in all four quadrants of the coordinate plane).
Coordinate navigator
Move horizontally for x, then vertically for y.
The coordinate plane, navigated.
01 Why is the order of (x, y) important? x first
(3, 5) and (5, 3) are different points: 3 right then 5 up vs 5 right then 3 up. The ordered pair convention is universal — x is always first.
02 How do the four quadrants get numbered? I, II, III, IV
Counter-clockwise from the top right: I is positive-positive, II flips x, III flips both, IV flips y. The shorthand: ++, −+, −−, +−.
03 Why does this generalize so much later? Foundation
Lines, parabolas, transformations, and 3-D coordinates are all built on top of (x, y). The earlier you internalize the address system, the easier they get.
04 Which grade is this game for? Grades 5–6
Grades 5–6, aligned with CCSS 6.NS.C.6. Direct ramp to graphing equations and functions in Grades 7–8.
