I think teaching the grammar first makes sense in German since this is the difficult and ugly part. In my opinion if this does not become a second nature you will be uncomfortable to communicate in German since otherwise you will always think uncofortable seconds how to build the correct case etc. . In other words: You will have difficulties becoming fluent if you aren't confident in the grammar.
