Education blogger Tom Barrett has compiled some great ideas for using Google Maps in the math classroom. Based on the crowd-sourced map, teachers can view activities for students between grades one and 5 (elementary). While this is an elementary map of math activities, the idea could easily be scaled to higher level math classes.
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.
