"Jenny, I understand you are upset. That is okay. Let's talk about this. First, you need to calm your body down. Do you remember how?"
"I need to hold my belly and say STOP! I feel angry." *begins taking deep breaths*
"Walk through your calm down steps."
"Great job Jenny! Now that you are feeling calm, let's talk about why you are feeling angry."
"I really want to play with the Legos."
"I understand that you want to play with the Legos. We are going to read this story and then we will be having free time and you will be able to play with the Legos. I would like you to wait until after our story and then you can play with the Legos."
