An important goal of DaZ (German as a Second Language) instruction is to enable students with a migration background to successfully participate 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 offers worksheets on the topics: definite articles and gender, articles in the dative case, emphasized/unemphasized personal pronouns, possessive pronouns, as well as a review game, tests, and information pages on vocabulary and grammar. The tasks are differentiated for basic and advanced courses, allowing for parallel work at two levels in heterogeneous learning groups.
