Compound Interest

In fourth grade, a banker came to my classroom to teach my class about compound interest. I was fascinated. First, I was shocked that a bank would pay me money to keep it safe, and second, I loved learning how I could make more money if my interest was compounded.  I memorized every single thing that would be on our compound interest test, and I did really well.  My mom even hung my A+ test on the refrigerator for a few days.
