Reflection: Diverse Entry Points Be Rational - Section 1: Set the Stage


I thought by making a connections to integer long division my students would be able to work more easily with simplifying rational expressions.  I learned that for some students the memory of struggling with integer long division was anything but a positive connection!  I had to think on my feet for a different way to help the students who got frustrated at the very mention of long division.  I decided to teach those students how to divide rational numbers as though they had never seen long division.  I even used a different format by having them look for multiples of the numerator first, then subtract without setting it up as an extended vertical problem.  I've included a student work sample for the second problem.
