Grammar exercises of a special kind: motivating context, playful approaches, real-life situations... this makes in-depth and repetitive learning enjoyable. In the first volume of this series, which is divided for grades 3 and 4, the focus is on parts of speech. In addition to the basic parts of speech—nouns, verbs, and adjectives—the special parts of speech are also addressed. Each part of speech is explained in detail, illustrated with an example, and practiced by students in various task formats through follow-up transfers. Learning success is guaranteed! The tenses: We cover four fundamental tenses. In addition to the present tense (present), we also address the simple past (preterite) and the present perfect, as well as the future tense (future I). Each tense is explained in detail and in a student-friendly manner, and can subsequently be deepened with differentiated practice exercises.
