I found this game on the appstore a few days ago, it's really fun to do and you can learn different languages. Fun for children but also for adults!
This is the explanation I found about this game!
Memory is a complete unique iPad application developed for children with the objective to provide them with a simple game memory combined with the possibility to learn a foreign language.
The application has a game board with 36 images that need to be matched.
Next to the images that need to be matched each image shows the word of the picture. The user can select the language he or she wants to learn.
The following languages are currently available: English, French, Spanish, and Dutch.
It is a fun way to train the memory and learn a foreign language at the same time.
In the future more memory cards and more languages will be added
