Make another transition into ordered pairs. Place another transparency on the overhead with the Cartesian plane and show the students how to plot points. Ask the students to guide you in plotting points that you have already chosen that are in different quadrants on the overhead. Make the observation to students that each one of the points is in a different section of the Cartesian plane. State that these are called the quadrants and discuss how they are numbered.
Students can now begin plotting themselves.
Arrange the desks in rows and find the origin. Those students that have an ordered pair on their cardboard must plot themselves. Those students then need to describe how they were able to plot themselves. Those students that did not receive an ordered pair, need to identify which quadrant a particular student is in. The students can be evaluated during the activity by observing if they plot themselves at the correct point.
