This cooperative learning activity leads students through the analysis of a walk from school to a sandwich shop. Students eventually write a linear equation giving the distance of the walker from school at any time. Students represent the situation both numerically and graphically in order to help them analyze the situation.
This activity is designed to work as a jigsaw activity. Four different walks are analyzed in groups. Each walk is slightly different (faster, slower, starts closer to destination, walks the opposite direction). After working on their individual walks, groups then shuffle in order to compare and contrast their scenarios.
Teaching notes provide tips for implementation and ideas for working with this activity in non-jigsaw formats.
Students should know: how to graph points, the concept of d = rt, and that two variables can work together in an equation.
