QuizGeo – Create, play, and share quizzes about geography (Gr.5-12)
“QuizGeo allows you to create and play quizzes based on geography using Google Maps. This can include anything from locating all of the countries in the world to locating all of the playground equipment at your local park or school. Since you place the questions on the map you can decide how large of an area your quiz will encompass.”
No registration is required to browse the list of pre-made quizzes, but is needed if you want to make one of your own. As of this post the site is still in beta testing, so please give them feedback so that they can make improvements to the service.
