Newseum is a great resource for social studies, government, and history classes. If you click on the Today's Front Pages link, you will see 760 front pages from newspapers in 76 countries. You can click on the image of a paper to view it larger. Not only are there today's front pages, but also archived pages and Top Ten (which shows the top 10 headlines from that day).
The Newseum keeps an archive of national and international front pages that chronicle events of historical significance....topics range from Super Bowl wins, natural disasters, weddings, elections, political events and more.
There is even an app for the iPhone and iPad!
Just a note, you probably want to preview the site before showing it live to students in case some of the headlines are controversial or inappropriate.
