Can you teach someone the hand model you learnt today?
Using your own hand, explain:
your emotional brain
your upstairs brain
what happens when you flip your lid
Then ask them:
"What helps you calm down when you feel like you're about to flip your lid?"
I like this because it's simple, reinforces the three core concepts from the lesson, and finishes with a conversation about calming strategies without becoming another teaching activity. It feels like a natural end to the module.
