Our final thesis deals with the issue of developing algorithmic pupils´ thinking in the first grade of primary school. Theoretical background analysis the current condition of the issue in comparison with the past. We briefly develop the topic of algorithmic thinking in schools at present. In addition to non-computer activities and software environments, various programmable toys and robots are increasingly being used. In the first grade, it is appropriate to use simple programmable toys as an introduction to more demanding programming in the second grade. In this work we deal mainly with the usage of the robotic bee Bee-Bot in informatics lessons. The output of the practical part of this work are processed into the methodological sheets with activities for students of the second and third year of primary schools. In DISCUSSION we focus on the activities verification of the methodological sheets, we evaluate the results and determine recommendations for practice. The use of Bee-Bot and other similar teaching devices creates a space for playful learning, that enables better and more efficient achievement of educational goals.
