Your lesson took less time than expected. How could you utilize the time left for your subject?

I would utilize the time to talk about something else related to social studies. Probably a current event. In some of my history classes at wvu instructors would do that and it was a good 10 minute time killer but one that was interesting and engaging. It allowed for a teachable moment a lot of times. Plus, one of the benefits of teaching social studies is that any current event is going to be something related to social studies. The recent economic downturn...economics. 2012 election...politcal science. All of these are social studies related and thus teachable at any time. Plus there is a ton of material (news websites, news channels, blogs, pictures, opinion pieces etc) to choose from.
