An intern at an electrical store calculates the power consumption of various electrical devices; the automotive apprentice uses the rule of three to create customer invoices; the roofing intern prepares a surface calculation for his master, and a nursing intern sets up a table. With these practical tasks, your students train mathematical topics such as addition and subtraction of fractions, percentage calculations, the rule of three, roots, unit conversions, and surface and volume calculations. At the same time, they get to know different professional fields. Therefore, these exercises are also ideal as preparation for internships. Additionally, important basic mathematical skills are practiced and reinforced at the end of each unit with "Train your Brain" tasks, ensuring that your students have a solid foundation.
