## Reflection: Debate Radioactive Decay and Nuclear Waste - Section 3: Share

An interesting conversation occurred when I presented students with two different ways to set up the equation for this problem. Some students insisted that the other equation was incorrect. It was a great discussion and students were very good about articulating exactly what the variable was representing in each case.

This is a prime example of MP3 and the importance of constructing viable arguments. If I would have only presented one solution pathway, I think we would have missed out on a great opportunity to recognize different ways to solve a problem and the need to inspect the arguments that others present.
