Lunch was too short. They were super-rammy when lunch was over, and it was very hard to re-focus them. After "silent" reading (not really silent) and a bathroom break, we read a snowman story. Now they're working on a journal called "All you need for a snowman is..." They're making a list of items they would need to build a snowman. It's still noisy, but at least now it's productive noise.
In an attempt to calm and inspire them, I'm playing Vivaldi's Four Seasons, "Winter." They like it, but they keep asking, "When are they gonna start singing?" :-)
It will never be 2:30.
