So far this year in a geography class, we have already covered Canada, Mexico and Central America, South America, and the unit we are currently on is Europe.  But we are specifically focusing on Germany in the European unit.  The four most important cities in Germany are: Berlin, Frankfurt, and Hamburg and Munich.  Berlin is important because it is the capital.  Frankfurt is important because it is the money making/ banking city.  Hamburg is important because it invented the hamburger, and because it is a port city.  And Munich is the manufacturing city which also hosts Oktoberfest.
