The coordinate plane

We use coordinates to describe where something is. In geometry, coordinates say where points are on a grid we call the "coordinate plane".

Coordinate plane

We first explored the coordinate plane in the 5th grade. But that was only dealing with positive coordinate. Now, however, we know all about negative numbers so why not have negative coordinates as well! Common Core Standards: 6.NS.C.6, 6.NS.C.6b, 6.NS.C.6c, 6.NS.C.8
