Oberprima is an online community similar to Khan Academy, where videos from teachers are put online to explain short teaching points. Mini-lessons. German spelling is not easy, so I found one video on explaining the spelling differences between s, ss, ß. I want to ask you, how old do you have to be to understand a video like this?
Can a 5th grader get this? After all, that is when this item is explained. I would say: YES.
What do you think?
