The mathematics goal of this activity is to deepen students' understanding of slope by solving two meaningful and relevant problems involving rate of change. In this activity, students utilize their understanding of patterns and algebraic rules to learn about slopes and y-intercepts. Further, they will make the connection between speed and slope and head start and y-intercept. This activity also develops the language that supports future mathematics learning.
Before the Activity
Load RateofChange2_Contexts.tns file onto all the students' handhelds. The activity consist of two problems: the first problem is designed to be teacher directed and the second problem is designed to be student centered with time for students to investigate and record their observations.
