I have my students spread out, sit or lay down, and close their eyes. I let them listen to about 2-3 minutes of music and then have them sit back on the carpet. I choose 3-6 students a week to share their stories, depending on how elaborate the stories are. I post the Youtube videos on my website each week so students can share the music and their stories with their parents/guardians!
You don't have to use SQUILT every week though! Use it as a brain break, an extra time activity, or just something fun and different. They can journal, draw/color what they hear, describe music using musical terms, or simply put their heads on their desks, close their eyes, and imagine!
Lastly, here are the musical selections I've used for SQUILT so far:
William Tell Overture Finale, Rossini
Shepherd's Hey, Grainger
Le Vent Dans la Plain, Debussy
Hoe-Down from Rodeo, Copland
