Coordinates

Two numbers name a point on a grid: how far across from the origin, then how far up, written (3, 2). The two number lines are the axes and they meet at the origin, (0, 0). The order matters: (3, 2) and (2, 3) are different points. With coordinates a shape becomes a list of numbers.

Depth 1 · Foundation

You can read and plot points on a grid, across first then up, know the axes and the origin, and describe a shape by the coordinates of its corners.
