Graphing on the Coordinate Plane Monday 9/19/11

Objective: Today you will locate and name points on a coordinate plane using ordered pairs of rational numbers.


Vocabulary: coordinate plane, origin, x & y axes, quadrant, x & y coordinate, ordered pair


After today you will know:
1. How to identify the x and y axis.
2. Which value in the ordered pair is the x and y coordinate.
3. That a positive x or y value is to the right or above the origin and a negative x or y value is to the left or below the origin.
4. The quadrants I, II, III, IV.
