I like the books used at the Deutschakademie. I find them very interesting as you do not only learn german gramma but also the culture, a bit of history and of course my hobby shopping. Serkan my teacher also tells us a lot about the history and tradition. At least 15 minutes is dedicated every lesson only for this purpose. One of such lessons was about the money in Europe and I found it very educative as I have been leaving in Austria for about two years and didnot even notice. So did you know that the Euro notes in all the European union countries are the same but not the coins. Sie haben zwar die gleiche Zahlenseite, aber auf den Rückseite haben sie unterschiedliche Motive.The German one and two Euro coins for example has the Bundesadler whereas the Austrian one Euro coin has the head of Wolfgang Amadeus Mozart. And what do you think is on the Austrian two Euro coin? :) Guess! and while you are still guessing please take a look and compare all the other coins its very interesting.
