I recently came across the "Explain it to me" series of videos on CNN.com. I think these videos could be really helpful introducing some of the more complicated current events (the Eurozone debt crisis, for example).
At 2-4 minutes a video, these could easily be included in lessons, or as review for students to view at home. The videos are probably most appropriate for middle or high school students. Videos explain things from North Korea to concussions to campaign finance to the Kardashians.
It's a site worth a look. If not for your classroom - maybe just for you!
