An important goal of German as a Second Language (DaZ) instruction is to enable students with a migration background to participate successfully in regular classes. Teaching fundamental grammatical structures is one of the most important tasks of support instruction. With the materials in this booklet, your DaZ learners can specifically practice essential grammatical structures. The worksheets are clearly structured and motivate students with their real-life content. The booklet includes worksheets on modal verbs in the present and past tense (can, like, should, must, may, want), a review game, tests, and information pages on vocabulary and grammar. The tasks are differentiated for both basic and advanced courses, allowing for parallel work at two levels in heterogeneous learning groups.
