We learn most of our geography from library geography and history books, but there are some very helpful websites with online map quizzes - they tell you the country or state and you have to pick it out on the map. Our favorite by far is at geoquiz:  http://www.lizardpoint.com/fun/geoquiz/index.html.   There is also Mapquiz.com (flags, countries & states), and  US Capitals.
