My idea for an ice breaker for college students would be to have everyone break off into groups containing three people (each person would be assigned a number 1-3 and would join a group according to that number).
The facilitator will speak to the groups before they begin, so that they are aware of the rules for the activity. The first task of each group is to introduce themselves to one another. Once they have done this, they should find 2 things that everyone in that group has in common (such as favorite holiday or movie genre but not including categories that are more “obvious” like hair color, eye color etc.). They will also find one thing that none of them have in common.
