I thought the tips to engage inattentive students was really helpful, because it is something every instructor deals with. The tips were:
Move to the area where the inattentive student is
Schedule discussion if needed
Put them in groups
Seating chart
Minute papers at the end of the day to summarize what they learned
I think the groups and minute papers are really helpful to do in general to curb that behavior before it happens. So, I will do that and move to a discussion or altered seating chart if it gets that far.
