Have you ever turned down your music when driving in a new neighborhood trying to find an address? What does music have to do with directions?
It is another input. Another distraction when all of your mental energy is trying to focus.
My classroom is old-hat to me. But to my new students? Everything is novel. Where the pencil sharpener is, how I pass things out, procedures for lining up. Literally, everything is new. So many inputs. And, unlike the music in your car, there is no button to tune some of it out.
The first month is kind of nuts. Take a breath. It'll get better.
