Like all parents, I was eating breakfast with my young children and quizzing them in the subject of mathematics.

There was one particularly difficult question that my 5-year-old son was struggling with. My 6-year-old jumped in and gave an answer. My son got angry. He stormed out of the room and started screaming and throwing things.

My daughter said, “Sam, you need to roll that anger into a ball and throw it out the window.”

I asked her where she learned that good strategy. She said her teacher.

I applaud those who have an awareness of their feelings and use calming techniques before they lose their cool. And I especially applaud the primary teachers who teach children these strategies.
