You are familiar with this situation from your daily teaching practice: In heterogeneous classes, children from various countries with different cultural backgrounds and varying levels of German proficiency come together. The materials in this book support you in specifically promoting DaZ (German as a Second Language) students and optimally facilitating second language acquisition. It particularly addresses linguistic and grammatical phenomena that these students typically struggle with. In addition to being used in support lessons, these worksheets can also be utilized for differentiated instruction in regular classes. The content covers various topics, including: Grammar: the four cases in connection with two-way prepositions, tenses, conjunctions, active and passive voice; Vocabulary: prefixes and suffixes, internationalisms, pairs of opposites; listening comprehension.
