Creating a shared Google map for your class

I've posted before about teachers using Google Maps for students to place annotated markers, routes, and regions on.  This can work well as a group activity, where each student creates a marker for a particular place on the map, for example.

Some ideas?  Create a map that marks important locations in a novel, or different regions in an area, or the routes taken on an historical journey.

I just wrote up teacher instructions on how to create a shared map in the first place.  If you'd like to give it a try, I hope these help.  I'm also happy to get you started.

The map below is editable.  Feel free to give it a try.
