Check out this Toolbox for Care developed by Facing History and Ourselves to help your class consider coping strategies for moments when feelings become overwhelming, especially during a crisis.
...This teaching strategy is designed to help students think about what “tools” they have access to that can help them take care of themselves and others in the wake of traumatic news. It invites them to create a physical toolbox containing “tools” that represent the skills, attitudes, and actions that are necessary to care for themselves and their communities during difficult times. This strategy helps students to reflect and to recognize what they might need to make a difference.
