## Reflection: Lesson Planning Multiplying and Dividing Integers - Section 2: Explore

I am really glad that I used expressions for the table challenge.  Substituting values in an expressions is an important algebraic skill, and I find that kids often do not understand the way that expressions are written - and thus do not simplify them correctly.  In this particular activity, I was able to clear up misconceptions on a term like "-a", when a = -2.  They were able to get the kinks out in terms of having a - - 2, and that led to greater success (well fewer questions at least) on the homework!
