This is a fun greeting to do with students. You begin this greeting by turning to your neighbor and holding up your right hand with your palm facing him. Then your neighbor puts up her right hand in the same fashion. The two of you lock thumbs, so that you form butterfly wings with your hands. When this is done, both of you wiggle your thumbs and greet each other "Good Morning or Good Afternoon". Continue this around the circle until everyone has been greeted in the butterfly wave. Be sure to remind students about what makes a friendly greeting: eye contact, face your neighbor, smile, clear voice, genuine, etc.
