In this article we present programming constructs taught to lower secondary school pupils in the context of educational robotics curriculum. It consists of eleven activities with robotic kit LEGO WeDo. Students develop many important skills, such as problem solving skills, programming skills, design and ICT competencies. The development of this curriculum was a part of our dissertation research. The students were in 5th and 6th grade (10–12 years old), studying the school subject Informatics. We used qualitative methods of data collection and data analysis. In this article we present programming constructs such as count loop, conditions, variables and parameters that most of the pupils in our classes acquired. These constructs were based on analysis of programming environment for robotic kit LEGO WeDo.
