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.

Is higher education a good investment? One of the biggest questions students face is how much education to get. While bachelors and graduate degrees may lead to higher earnings, they can also be expensive and take years to earn.

In this lesson, students write and solve systems of linear equations to determine how long it would take to pay off various degrees and discuss the pros and cons of different educational paths.

- Professions have different upfront costs (both time and money) for education, and they have different median salaries after that education is attained.
- Some professions with high median salaries require lots of time and money for education in the short run.
- Whether someone “should” get more education depends on what’s important to them – e.g. netting more money, doing particular type of work, having a particular status – and how long they expect to work.

- Write linear equations to model real-world scenarios
- Solve systems of equations graphically, algebraically, and/or by reasoning with tables
