Direct Variation  This chart simplifies the idea.  Then this year I was talking with another teacher who wondered why we call the rate of change "k" in a direct variation and then "m" in the next chapter for linear equations.  Duh..why didn't I think of this?  For a kid that is already confused with math and using letters, we shouldn't be changing up letters like that when it's really the same idea.  So I nixed the k this year and just stuck with y = mx as the equation
