Quiet down a line by singing a song. My rule is sing or be silent! This was an accidentally-discovered trick. One day I FELT like yelling, but started to sing instead. It changed my mood and it worked MUCH better than crabbiness. When we finish a song, I immediately put my finger to my lips for quiet. It works almost every time.
Play soothing instrumental music when the kids are writing or doing silent, independent seatwork. I play the same CD every single time, and it's almost like the music prompts my students to write steadily.
Discover Spotify. Spotify is a music site that allows you to form playlists. There is a fee if you don't want ads. If you are planning to use Spotify in the classroom, you do NOT want ads! Trust me on this one. Once at home, I had to rush to turn down the volume because an ad came on that I did NOT want my children to hear! That's never happened in the classroom, because I pay the small fee for a subscription. It's WELL worth it.
Practice reading skills and build fluency using songs. Have students circle rhyming words, find word patterns, underline sight words or contractions, etc. Then, play the song as students follow and sing along.
