Easy and simple yet can be quite enjoyable and unifying. The idea is to go around and give each person a chance to talk without interuption about their day, their feelings, anything really by saying check-in before beginning and check-out at the end. Between check-in and check-out, no one but that one person can talk. When done regularly, for instance a check-in every night before bed, can be a most powerful positive influence that can help sort out group issues and lead to becoming a cohesive group.
