How do traffic lights work? How can I learn to program a simple drawing robot? On the basis of models taken from everyday life and tasks that build on each other, children learn key digital skills step by step. With the aid of an easy-to-operate controller, practical sensors and actuators, an intuitive Scratch app, models that are quick to set up and the colourful fischertechnik building blocks, primary school children solve tasks they are familiar with from their living environment. Thanks to the playful hands-on approach to learning, children also develop important social and emotional skills.
