I noticed this on a past post in the FREE TECHNOLOGY FOR TEACHERS blog.
National Geographic has a daily user-generated photo gallery called the Your Shot Daily Dozen. The Daily Dozen is similar to the BBC's Day in Pictures series. The Daily Dozen contains user-submitted pictures from around the world.
National Geographic has two activities that students can use based on the Daily Dozen pictures, a jigsaw puzzle and a memory game. These activities could be a fun way for students to develop memory skills, matching skills, and puzzle solving skills.
Images could be used as conversation starters in current events courses, environmental science classes, or photography classes. The images could also be used as story starters for a creative writing class.
