From the LSA Inclusive Teaching Initiative, University of Michigan:

• "Some of these icebreakers may be more suitable for students who are already comfortable with one another. Save those activities for later in the semester.
• Not all students enjoy icebreakers, and some may see it as a waste of time. Being straightforward with your students about the function of icebreakers may help students recognize the positive benefit of taking class time to do them.
• Be aware of space limitations and any disabilities that may inhibit a student’s ability to participate fully."
