Over the years I frequently used resources like the BBC’s Week In Pictures and Ten by Ten to give students visual prompts about current events. I found that the pictures often sparked more questions from students than just giving them a news article to read. The Getty Images Stream iPad app could be used for the same purpose.
Getty Images Stream features photographs from Getty photographers all over the world. Select a category to flip through a set of related images. You can also enter a search term to find images. Long press on any of the images to bring up some brief information about the image. You can also save images into a collection of your own in the app.
