Zahlenzorro - The Basic Workbook 1 Mathematics introduces favorite themes such as circus, fantasy, detectives, or pirates. The Zahlenzorro Basic Workbook 1 includes the complete learning material for the first grade, designed for independent learning, practice, and deepening - whether at school or at home in the afternoon. Self-explanatory and independent of any specific teaching materials, Basic Workbook 1 motivates students through the theme of "Circus," which guides children throughout the entire workbook. The tasks are embedded in the world of the ring, clowns, magicians, performers, and acrobats, tailored to the interests of the age group. Accompanying them is the Zahlenzorro, who supports students with questions and assistance. A removable answer booklet allows children, parents, and teachers to quickly and accurately check their results.
