2023-2024 Versions

In the fall of 2024, Citizen Math released updated versions of every lesson in our library, plus a few new ones! We know you may have already prepped an earlier version or planned a repeat of last year, so we're continuing to make these earlier versions available through Thursday December 5, 2024.

You can find the new lessons through the regular search, and we hope you love them as much as we do. You can read more about these updates in Our Community.

This lesson will be retiring and a replacement is coming soon.

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.

REAL WORLD TAKEAWAYS

  • In a relationship it’s important to be able to relate to the other person – to have common experiences and shared priorities and mutual interests. Age is one factor that might contribute to or hinder this, but it’s certainly not the only one.

MATH OBJECTIVES

  • Write linear inequalities from a verbal description
  • Graph a system of linear inequalities with a domain restriction
  • Write and solve inequalities to answer real-world questions
  • Find an inverse function

Appropriate most times as students are developing conceptual understanding.
