In an ever-increasingly diverse workforce, cross-cultural communication skills are essential for success regardless of job title or task. We present an engaging and customizable 30-minute activity designed to develop participants' cross-cultural communication skills by increasing awareness and sensitivity to interpersonal differences in collaborative group settings. Drawing from a multiculturalism approach to diversity, participants learn that acknowledging our differences facilitates more effective and strategic communication. We provide detailed instructions for running this exercise to meet instructors' and students' outlined learning objectives. The debriefing questions and post-lesson reflections support an environment where facilitators and participants grow. This experiential exercise suits any discipline's synchronous undergraduate, graduate, and professional classes.
