The three-volume series Familie Grammi consists of workbooks (Arbeitsbuch), in which the grammar and syntax of the German language are gradually practiced at a basic level (A1-B1). The series is mainly aimed at middle school students, although it can also be used by younger or older students. Starting with the first volume in a beginner's class and reaching the third volume in the third grade - that is, one level before the Zertifikat B1 - the series covers all the material of levels A1, A2, and B1 and thus easily combines with any Kursbuch and any three-volume teaching series. The easy adaptation to the lesson is facilitated by the glossary that accompanies each exercise.
