In this lesson, students are given the task to determine the number of cups needed to reach the height of their teacher. The only information given is the height of the teacher and the height of one Styrofoam cup. Students are to work with a partner to determine the number of cups with only the materials of four cups, a ruler, and their math journals. Once the number of cups is calculated, the next step is to come up with a linear equation to model what the students discovered. This interactive activity focuses on modeling and creating linear equations in an engaging way that challenges the minds of the students.
