Task# High School Graduation

Illustrative MathematicsVaries

Students will need to make the assumption that the principal reads the names at a constant rate to solve this problem. While not a full-blown modeling problem, this task does address some aspects of modeling as described in Standard for Mathematical Practice 4. Also, students often think that time must always be the independent variable, and so may need some help understanding that one chooses the independent and dependent variable based on the way one wants to view a situation.
