My students love to play around with Google Maps, but I've never used them in instruction. As a librarian, I got excited when I read the idea of creating Google Lit Trips or mapping significant locations tied to research. I followed the directions of Eric Curtz to create a Lit Trip using Google Tour Builder about the Civil Rights Movement.
The image below shows the dashboard for creating the tour with Google Tour Builder, but Eric Curtz provides directions for importing it into Google Earth.
Matt Miller's blog post, 20 ways Google MyMaps can enhance lessons in any class, has given me lots of inspiration for other uses of Google maps, too!
