Try using this Desmos activity called Pomegraphit to introduce the need for number plane instead of a number line.
This interactive graphing exercise would work well as a test of class comprehension. It scales from 1 to 4 quadrants easily.
Graphing and the Coordinate Plane (Interactivate) is a lesson plan designed to introduce students to graphing ordered pairs of numbers on the coordinate plane. Download the graph paper (PDF 30kB) and read suggestions for playing the General Coordinates and Maze games.
The lesson plan Getting to the point (Utah Education Network) includes PDF activity sheets, graph paper (PDF 39kB) and links to other sites.
PurpleMath has an extensive three part module with text explanation and supporting diagrams on the Cartesian plane: Introduction to the plane, Plotting points, The four quadrants.
If the other Desmos activity worked well, this marble mini-golf game could be useful review for students while introducing the idea of lines on the plane.
