This video tutorial describes the relationship between number lines and the coordinate plane.

In this lesson, you will learn how to describe or name the location of points on a plane by using the coordinate grid system. [2:55]

This video provides an introduction to all four quadrants of the coordinate plane. As you watch and listen to the teacher and student interact it helps clarify the thinking behind applying this concept. [5:28]

Tutorials that show the origins, X and Y coordinates, etc.
