Ship ahoy with numbers from 1-20. Where does the banana box go? Is this the place? At the harbor, the sailors load valuable freight in their ships. Each ship is distinctively large and must be loaded in the best way possible. Which ships fill up first and can begin the adventure on the high seas? The counting captain offers numerous exercises for the playful training of addition and subtraction in the number range from 1-20. The captain supports number understanding and promotes logical thinking. The option of playing alone lets children play and learn independently. —description from the publisher (Translated by W.
