In EDM, students worked on Khan Academy to sharpen their addition and subtraction of fractions with unlike denominators.  Students were broken into different groups where some were working on tasks with Mr. Giomini while others were computing sums and differences while also reporting their answer into simplest terms.

What assumptions can be made about
experience and income?  What
profession might this be applicable? 

Just some examples of scatter plots.

What is the correlation?
