Successive Differences

Activity Overview

Students explore the relationships between the side length and perimeter of a square and the edge length and surface area of a cube by manipulating geometric models. They use the models to generate a dataset, calculate successive differences, and use them to determine which type of function best models the relationship. Finally, they graph the data set as a scatter plot and use the regression tools to evaluate their conclusion.
