I love using group activities for a learning experience. Although the course recommends 5-6 people per group, I tend to keep the groups smaller. I don't like to have more than 4 people per group. The larger the group, the more often one or more members tend to not interact and contribute to the project.
I loved the idea of presenting a pre-group project to have them get to know each other a bit better and to practice working in an environment that is "low stakes". Often, we will have groups work through a case study and have them role play the scenario.
