How should Arlington National Cemetery plan for its future? Established in 1864, Arlington National Cemetery is the final resting place for thousands of American soldiers. Unfortunately, the Cemetery is running out of room, and there’s no simple solution for what it should do.

In this lesson, students write and solve linear equations to estimate when Arlington National Cemetery will reach capacity, evaluate various proposals to prolong its lifespan, and debate the best way for Arlington to honor soldiers and their families.

Students will

  • Interpret non-linear graphs
  • Create tables, equations, and graphs to model linear relationships in the real-world
  • Solve linear equations

Before you begin

This lesson is appropriate for students who have not yet mastered writing and solving linear equations when students are given the time and freedom to tackle questions intuitively and creatively.
