- Teacher Vision is a great online source of ideas. While Teacher Vision is subscription based, they offer five free printable resources and a free-trial. Lessons range from strictly US and world geography to incorporating geography into other subjects, like earth science, math, and language arts.
- The Library of Congress has a wide selection of online maps and geography resources that can make their way into the classroom. Online maps can help with spatial understanding, and there is even a link to an online “Earth as Art" exhibit using Landsat aerial images.
