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.

Law of Exponents - Multiplication with Like Bases

Unit 2: Exponents and Radicals
Lesson 5 of 19

Objective: Students will be able to conceptually understand exponents to expand multiplication involving exponents with the same base. By expanding the multiplication, students will develop the rule of adding exponents when multiplying with the same base.

Big Idea: Memorization is short term knowledge but understanding endures time. Create the rules for exponents by expanding the bases to understand.
