Thanks for the kind offer. This is their first year so they are definitely beginners. They are working on a project now for their midterms. I'm sure they wish I would let you help.
Maybe when it is just homework. Actually it is kind of a fun project IMO. They have to write a paper in German about what they did this week and then give a one minute talk about it in German.
I wish I had projects like that when I took French. Ours was just boring read and repeat. They are doing a food project next. I love the way the teacher is showing them the customs of the country and not just the language.
