Mathalicious: Datelines

How much does age matter in a relationship?

While some people believe that love knows no bounds, others think that partners should still be relatively close to one another age-wise.

In this lesson, students use a system of linear inequalities to explore the popular dating rule-of-thumb, ‘half plus seven’, and debate how important age — and other factors — are in healthy relationships.
