Through this activity students will build an understand for slope by relating it to distance-time graphs. Students will think about the speed at which they are walking and the direction and how these affect the graph being produced. The activity uses the calculator based ranger (CBR) and the TI84 graphing calculator. With the CBR and the graphing calculator it is possible to view real time graphs produced by students.
Included in this activity is an assignment about distance-time graphs. Solutions are included.
