Background For Teachers:
You can use a coordinate grid to locate points on the plane. The x-axis and the y-axis are number lines. They intersect at right angles at their zero points, the origin. Any point can be located using an ordered pair. The first coordinate tells you how far to move on the x-axis from the origin. Coordinates of points to the right of the origin are positive numbers. Coordinates of points to the left are negative numbers. The second coordinate tells you how far to move on the y-axis from the origin. Coordinates of points up from the origin are positive numbers. Coordinates of points down from the origin have coordinates that are negative numbers.
Students should understand the following vocabulary for this activity:
Intended Learning Outcomes:
Have students draw a four-quadrant grid with all quadrants
labeled. Then plot two given points in each quadrant and label
them with the correct ordered pairs. Example: A(3,5); B(3,-4);
C(0, 4); D(-2,0); etc.

In general, organizing students in cooperative learning groups has a powerful effect on learning regardless of whether groups compete with one another.
