Teachers, if you are looking for resources to talk with students about genocide within a safe, compassionate framework, my friends a Journeys in Film can help.
They have standalone guidelines for facilitating topics on difficult discussions: https://journeysinfilm.org/product/facilitation-guidelines/
They also have a lesson for teaching about Genocide in their Francesco film guide: https://journeysinfilm.org/product/francesco/
I'm sharing in case this is helpful to any of you.
