My students have been a bit bonkers being off of their regular schedule. One of things I do to gain their attention is an Attention Grabber prompt. I say one thing and they say their line in return. I have trained my class to be silent and wait for directions once they have said their line. Sometimes, I may have to say the line a couple of times. Overall, it gets the students focused without me screaming. One example is "Hear ye, hear ye...All hail the queen." I love that line! Eventually, your class may get creative and try their own lines.
