Use this sign to tell your class if you expect them to raise their hand or to have a discussion. You can change it whenever you need to change the dynamic of your class conversations. If you would like to hang the sign on a string and flip it from one side to the other, print the first page. If you plan to have it on a clip and turn it over, print the second page. Then all you have to do is fold on the black line and hang it up! I recommend laminating it to keep year after year.
My students know to check the sign when I ask a question. When things get too loud or people are interrupting each other I can change the sign to "raise your hand" and when they all have answers or they're shy about participating, I set it to "class discussion".
This is an excellent way to utilize non-verbal cues (can you tell I'm a special ed. teacher?!) and to maintain your classroom management. All students know the current expectation.
