Word and sentence grammar are part of the mandatory learning content in elementary school. Through the varied exercises in the workbooks, children learn to recognize parts of speech and distinguish between sentence types. They also expand their knowledge of word formations, word families, and fields of vocabulary. The exercises help children to write correctly and simultaneously promote their linguistic expression skills—competencies that are required by educational standards. The practice options are diverse: fill-in-the-blank texts, word games, puzzles, and coloring pages with words and numbers. The opportunity for self-assessment supports independent work.
