## Reflection: Checks for Understanding Radioactive Decay and Nuclear Waste - Section 2: Explore

I found myself using this lesson as more of a formative assessment on logarithms than I anticipated. While students were working in their table groups I was really focused on seeing what they remember about logs. Even though some students could not solve the problem - they realized that logs were needed, and that was a huge step. Some students remembered the change of base formula while others did not.
