I use these during my stations, but they can be used anytime!
Our “code word” is “waterfall.” When our noise level gets too loud, I (or a student) says this. The class responds “shhh” & its our signal we need to take our voices down a level.
When the code word has to be said, a letter is flipped over, starting with “e.”
When the cards say “no,” there is no more talking in our stations.
This tool has worked very well for my class & as the year has passed, we don’t have to use it as much.
I hope it works for your class too!!
