During free time or fun activities, kids like to have music in the background. They can learn a new dance to the music or just have free dance time. They will all want to bring in their own music--so, organize it by having a sign-up sheet available. Leave space for the name of the student, the title of the song, and the performer. This way you can listen to the music ahead of time for appropriateness. You may also want to have a rule about students looking at the list to make sure they bring in original music.
