Here is what Mr. Lewis's classes looked like on Wednesday, 9/3/2014:

Coordinate Algebra Support:

We looked at doing lines of best fit by hand.  We discussed what the slope and the y-intercepts mean in context.  We also discussed correlation and whether correlation always implies causation (the answer is no!).  We watched videos of a class developing data to use in order to find a line of best fit.  We then practiced on the homework from Tuesday.

Accelerated Precalculus:

We reviewed for our test, scheduled for Thursday.  Topics are: graphing trig functions; inverse trig functions; and, word problems.
