Life of Fred

We're using math books called "Life of Fred," in which the math is all introduced story style before kids are asked to learn how to do it. Today, the story introduced exponential growth and decay, teaching the kids how to create equations describing it. While going over his problems, I saw that Emmett was creating equations like (0.88)^x = 0.2. (This one was a problem about the value of a car decreasing 12% per year over time until it only had 20% of it's original value.)

Emmett hasn't yet learned how to deal with variables in exponents, but after we talked about the equations, that was the first thing he asked. I'm guessing logarithms are coming right up, and Emmett can't wait because he wants to know  how to solve those problems he just set up! Just a little example of how masterful Stanley Schmidt has been in setting up these books. :)
