Grab some red, yellow, and green Solo cups (or any brand will do) and improve your small group communication! I have each team take a set of three colored cups when they set off to start groupwork. They begin with a green cup on top. If they need teacher assistance, they move the yellow cup to the top. This is a signal to me that I need to check in with that group soon. If a red is on top, that means the group needs me right away and cannot move forward in their work until I stop by and answer a question. By using these communication cups, I can scan the room and identify when group I will go to next.
