As some of you know, I have been on a bit of a "college" kick as of late. When we were working on linear equations and systems of equations, we did a project on the cost of college. So, when some of students came around to compound interest, I thought, college loans were a great real-world application.

Students used real data to determine how much they were likely to need to borrow to pay for college, the different loan options (also real), and how much the loans would cost them in the end.

Some of my students are closer to college than others, but for all of them the project was pretty eye opening. Of course this launched a much bigger discussion about the value of college. I hope they all go and succeed, and at least now they will go with their eyes open. Oh, yeah, and they saw yet another application for the math they sit in class doing day after day.

I'm a huge fan of the real world applications you use with students, and it's a great bonus that in this case the math helps students understand something substantially relevant to their lives and futures. Thanks for the post!
