## Reflection: Intervention and Extension Change of Base Formula - Section 4: Closure

As I was working with students on solving, I realized that many students were confused with the items we had been discussing. I decided to make Review Problems for station day worksheet because many of the students were not doing any work outside of class. I wanted students to focus on some key ideas we had worked on in this unit.

When the students received the worksheet they immediately began working on the problems. Some were upset that they did not know how to do the problems but this should indicate to the students that they may need some extra help.
