## Reflection: Developing a Conceptual Understanding Express This - Section 2: Explore

This was a difficult activity. I think that this concept would be better introduced as a problem for a discussion POD to build some initial understanding before we try a complete activity. Or maybe posing the idea in general to get some feedback before trying to walk through the activity would be better. There was too much confusion for them to work through. A guided activity as a whole class may have been a better approach.

This was hard!
