Sometimes when kids come in, I will have music playing. Other times I used it as part of my lesson. Sometimes I play relaxing music to keep them calm and quiet. Music can be used as a timer or transition. Really music off youtube is great for almost everything in my classroom.
But today. Today it had one purpose. Indoctrination.
I think I played it at least 2-3 times during each period; plus another 1-2 during the hallway passing period. And... allow me just to say... I miss happy valley. Up here BYU is definitely in the minority. But I wouldn't let my kids put it down or me down. I told them that since I was the only adult in the room with a college degree, I got to pick the music. And if they chose to go to the rival school, that is great. I hope they do go to college. But for today we are supporting my alumni! :)
