Whether invoices in a café, a true-to-scale drawing of a plot of land for gardening, price calculations for a discount campaign in a supermarket or the duration of a work order in a printing shop - mathematics is needed in every profession. With these tasks, your students practice mathematical basics such as addition and subtraction, percentage calculation, conversion of units of measurement, as well as calculations of circumference, area and volume, using concrete job situations. The tasks are easy to understand - and thanks to the particularly small-step solution aids, all students will find the right solution.
