The Activity

Consider the activity models and answer the questions provided. First reflect on these questions on your own briefly, before discussing and comparing your thoughts with your group. Appoint one member of your group to take notes for the group, and appoint another member to discuss your findings with the class. After class, think about the questions in the reflective prompt and respond to those individually. Report out on areas of disagreement or items for which you and your group identified alternative approaches. Write down and report out questions you encountered along the way for group discussion.
