The subject of economics is often seen as unattractive by students, even though understanding economic relationships is immensely important for them in a complex working world. In this volume, economic thinking and action are practically explored through a fictional company called "REDBLU." Students become familiar with all the important business processes involved in developing a new skateboard model, calculating sales, producing the skateboards, and ultimately bringing them to market. They also learn how to search for employees and how to handle conflicts. All aspects related to administration, production, and sales are addressed through action-oriented tasks. This way, students learn to think economically and discover how exciting economics can be.
