Nonverbal cues

The prompt for this post reads, "Explain ways you have effectively used the following nonverbal cues." There are no cues listed so I will just write about some nonverbal cues that I use or have used. When I was teaching in fourth grade we used a hand in the air to signal "give me five" then I would count down with my fingers. Sometimes I would count out loud, sometimes not. I would also put a finger to my lips to signal students to stop talking. I know in middle school if I have told students to be quiet, and then they are still talking when I want to teach, I just wait silently at the front of the room until people realize and stop talking. I also give certain looks to students if they are not doing what they are supposed to be doing, a head shake no works well. I can give positive nonverbal cues to students as well if they are on track.  I am having a hard time thinking of others right now. I will post more as I think of them.
