The workbook allows students to work on tasks and exercises related to the fundamentals of commercial calculations and Excel spreadsheet management at their own individual learning pace and with self-chosen focus areas. This way, existing knowledge can be activated, expanded, and deepened, while new knowledge can be built, applied, and secured. Trainees in warehouse logistics will also find the required curriculum content within it. Therefore, it is particularly well-suited as a supplementary resource for lessons or for differentiation. In the IT section, the focus is on exploring warehouse logistics business processes that can be represented and optimized using spreadsheets. All tasks and exercises are based on the model company "Spitze Bau- und Leuchtstoffmarkt GmbH.".
