9/16/15: Lessons 3.2 & 3.3: Rate of Change, Slope, Unit Rate

All of the three concepts in the title above are tied together--basically the same.  (Unit rate always has a denominator of 1.)

We are completing Lessons 3.2 and 3.3 by this Friday.  The outcome is that students can find the slope (rate of change or unit rate) off of a graph, off of a table, and off an equation.  Because this is heavy-duty material, I wanted to use today's class time to present the foundations well.  Homework would be counter-productive tonight; no homework was assigned tonight.  You can expect it to resume Thursday night (tomorrow).
