## Reflection: Problem-based Approaches The Normal Distribution - Section 2: The Normal Distribution and the Heights of Men in the United States

The purpose of these eight Normal Distribution problems is to help students develop their notes about how to use the normal distribution and standard deviation to estimate population percentages.  I explain this to students, and I tell them that I'll be circulating to help make sure that their notebooks are full of useful, well-documented examples.

I let students get to work until questions arise naturally, and as work time begins, I start my laps around the room.  I have no prescribed method for how a notebook should look in my class, because these are older students and I like to allow to do what works for them.  With that in mind, this time will function as a notebook workshop, as I'll give each student a little feedback and if necessary, some suggestions about how to make their notebook as useful as possible.

For the problems themselves, I've included a brief Explaining the Math document that explains my thinking behind each one.
