This activity is designed for students to complete BEFORE learning about slope-intercept form. The hands-on, cooperative learning activity introduces students to the notion of slope-intercept form and shows them how it can be used in a real-life situation. You will be impressed with how well the students will work toward finding a solution to the challenging problems in the Tower Activity.
Students will determine the height of one Styrofoam cup by placing the cardboard on top of the cup and measuring with a ruler. They will place another cup on top of it and measure again, continuing until there are five cups on top of the original. The activity will ask students to make predictions about how many cups would be needed to create an 8672cm tower, as well as how tall a 1000-cup tower would be. It will lead them through determining the slope and y-intercept, and students will be able to test their predictions by using substitution with the equations that they create. Of course, they will graph results, as well.
