Reflection: Student Communication The Difference Between Mass and Customary Weight - Section 3: Group Work


I chose an exploratory activity like this because students, on their own, have struggled with this concept. I felt it was better to have students work together, and debate, only 5 objects to begin with. I didn’t want them to feel rushed to complete a lot of questions. I also wanted to spend time walking around and listening to their dialogue so that I could get a better idea of where they were getting stuck or confused.
