• You can begin by recognizing that it was a long night, everyone is likely very tired, different people have strong emotions from a variety of perspectives, and it may be hard to focus.  
• You can give your students a brief chance to write for a minute or two -- to process their thoughts and feelings and/or identify people they want to reach out to later today, for whatever sorts of connection and processing would be beneficial to them. And then move on to your plan for the day. 
• You could note the difficulty of focusing and of controlling strong emotions and let students know they can feel free to step out of class if they need a minute to refocus.

If a student raises the election as a topic when you hadn't planned to discuss it, these resources may be helpful if you want to engage everyone in conversation. If you do not feel prepared to do so, you can recognize why the student might want to have the conversation, but explain that you want to think further about whether and how to engage it as a class because it is important to do so carefully given the intense emotions and divergent perspectives around this election.
