Computational Thinking has become an important concept for almost all age groups. It describes the purposeful utilization of Information and Communication Technologies for solving problems. The approach of Computational Thinking and Acting combines the computational thinking approach with physical computing, including physical activities to explore real-world problems and tangible outcomes. In this paper, we present a competency framework, design principles, and a sample learning scenario for Computational Thinking and Acting. The evaluation has shown that the approach can be integrated across subjects and is promising for both teachers and pupils.
