Maslow's Hierarchy of Needs tells us kids can't learn if their basic needs aren't met-- do they feel safe?
Empower children to feel in charge of their own self-regulation when they feel their emotions are overwhelming them, but having a safe space in the classroom kids can go to whenever they feel they need it, and stock it with a lot of choices to help them learn to calm down independently.
Self-regulation is hard, especially when you are in a heated moment. By practicing each tool, how to use them, and using them with a trusted adult during prickly moments, kids can learn to self-regulate through co-regulation.
