I am looking to increase my German vocabulary and am looking for a good series of flash cards that does not contain any English, but instead just has pictures and the German word. Does such a thing exist? I have tried Googling, the Apple Store and Droid Store, but have always found flash cards with English words.
There are some
[Kartenspiele für den Deutschunterricht], there is for example a page
Wegerer.at has also some nice pdfs.
On this Goethe Institut page, there's a cute Flash game (Spiel 03: Memo-Spiel) that does what you're looking for. Found it by searching on ""memo-spiel" bild wort lernen wortschatz", if you keep looking you may find more. Tried the search with "Memory-Spiel" instead of "Memo-Spiel" but got only links to articles not games. Possibly "Memory-Spiel" is trademarked and reserved to the original publisher.
You could make your own: glue a picture to a cardboard square, glue a word to another square. Repeat with additional word-picture pairs. Turn all squares face-down and start having fun!
