Using Tennis Court To Teach About Coordinates and Graphing

Today we used the tennis courts to teach about graphing and coordinates. We used chalk to draw the x and y axis. We numbered both axis in meters. After a brief explanation about how this is just another way to organize things we had the students draw the court with the graph. We then plotted the students on their diagram. With 5th grade we talked about making lines. We had the kids make parallel and perpendicular lines with the other students. We used a tennis ball to show how we could plot the line that it rolled on. We showed the students the difference between a ray and a line segment.We talked about how when we serve the tennis ball we always serve to the opposite side quadrant.
