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.

- Arlington National Cemetery is an important and historic burial ground for members of the U.S. Military, and it is expected to run out of space within the next 25 years unless more plots are created or eligibility is restricted.

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