The image of a "human graph" is a powerful one when looking at graphs of lines and intersections of lines. The technique of having participants become "points" helps them to visualize slope, intersections, intercepts, and properties of functions. You will need a large space that has the x and y axes laid out, either in chalk or tape, depending on where you choose to do the activity. If the weather is nice, this is a wonderful activity to do outdoors.
Ask eight participants to volunteer to stand on the integer points on the x axis between and including -3 and 3. Then follow the directions given in the student guide for Problems D1-D10. For those participants who are not directly involved in creating the "human graphs," have them record what they see on graph paper.
