Even when students can correctly calculate interest, I find they often don't quite understand what it is or how it is used in real life. This webquest has students investigate interest rates for different scenarios they will encounter in the future (car loans/student loans/savings accounts/etc.).
I use this to introduce the concept of interest and pair it with the BrainPop credit card and interest videos, quizzes, and activities using my school's subscription.
