This is an example of an ambitious geography project carried out by a team of 7th grade teachers. Students created a class globe/atlas with Google Maps and kept an explorer's blog about their "Amazing Race" circumnavigating the globe. This project integrates a lot of content while also being student-directed and offering some choices.
Google has made it a point to create resources for educators and curate models of how educators have used their tools to help inspire teachers new to the apps. On this page, Google has created a list of models and ideas for using Google Maps in the classroom, including a getting started guide. Check this page for a few ideas and for ways to submit your models.
