Where On Google Earth is Carmen Sandiego? - A Great Geography Game

The theme song for Where in the World is Carmen Sandiego? is an earworm for those of us who grew up in the 80's or early 90's. And thanks to Google's new partnership with Houghton Mifflin Harcourt, we can now share the fun of Where in the World is Carmen Sandiego? with our kids.

Where on Google Earth is Carmen Sandiego? isn't exactly like the old version that you might have played from floppy disks, but it's fun and could be a good way for kids to apply their knowledge of geography.
