Play hide and seek with toys
For this game one player (e.g. the parents) hides an object and the other player (e.g. the child) has to seek it. The object can be a pen, a toy or the favourite teddy bear. After finding it, the child should describe in German where it has found the object.
For example: behind the plant, under the bed, in the cupboard...
This way the child practises the prepositions and corresponding articles in German in a playful way!
