Draw a rectangular coordinate grid either on an overhead or the board. Make sure you label the xaxis and yaxis. Show the students how to plot an ordered pair (x,y). Make it clear that the first number represents the location on the xaxis and the second number represents the location on the yaxis. Where the two meet in the middle of the quadrant is where the point is plotted (drawn). If this is the first time your students have plotted ordered pairs it may be best to only use the first quadrant and keep the numbers positive. If your students are ready for negative numbers you could use all four quadrants. After the students practice plotting a few ordered pairs and identifying the ordered pair from a few points on the grid, have them begin the activity. Ask students to plot the following ordered pairs. Have them connect the points in the order they are listed to make the shape of a house. (20, 0) (13, 0) (13, 8) (9, 8) (9, 0) (2, 0) (2, 14) (0, 14) (11, 22) (22, 14) (20, 14) (20, 0) Have students get a new sheet of graph paper and design their own connectthepoints picture or shape. You may want to limit the number of points that the pictures can have in order to finish in the allotted time. When they are finished, they should list the ordered pairs for the design in the order that it needs to be drawn on a different sheet of paper and give it to someone who has not yet seen the design. Each student should plot the ordered pairs and draw the picture or shape of his/her partnerâ€™s design. Have students share their designs with each other and vote as a class on the best design, the most complicated design, the most realistic design, or whatever seems appropriate.
