## Reflection: Developing a Conceptual Understanding Law of Exponents - Multiplication with Like Bases - Section 2: Beginning the Activity + Homework

I have had great success with this lesson as a means of building conceptual understanding.  Students are more successful when they start with numeric bases and eventually move into variables and then a combination of coefficients and variables.  As the expressions become more complex the students are ready to take their understanding of the property of multiplication with like bases to the next level.  I have in times  past used other activities that were given to me but less complex, all numeric bases only, and when it I asked them to practice with expressions that included multiple variable bases they were intimidated.  This activity is just the right mix of simple and complex to help them building an understanding with grade level work.
