Mnemonic phrases, learning rhymes, song bridges - we have always used songs or rhymes to memorize important rules or customs. This tradition is the foundation of LeLiBu, the learning songbook, a current collection of songs for elementary school age that promotes the learning and consolidation of various educational content. This connects two important elements of collaborative learning: the communal and motivating singing of songs and the simultaneous expansion of knowledge conveyed through the lyrics. The message of the text is supported by many colorful illustrations, making it accessible even to children in the first grade - ideal for school and home. The LeLiBu 1/2 package includes: the book with over 60 songs and spoken verses related to the subjects of German, mathematics, and general studies.
