In order to make it possible, it is necessary to prepare and train educators for teaching that leads in that direction and to provide them with the necessary "material" as well. One of those "materials" is the BBC micro:bit device - a small technological invention with many possibilities of use in teaching Informatics and many other subjects. The purpose of this thesis is to analyze teaching activities during the introduction of visual programming tool, BBC micro: bit devices in primary school teaching. The application of the BBC micro:bit tool has been shown in the teaching of Informatics in the fifth and sixth grade of primary school, since the subject of Informatics is introduced as a compulsory subject. The thesis is consist of a theoretical and a practical part. The theoretical part explains the role of information and communication technology in the educational process, the history of computers and the basic guidelines of teaching Informatics. In the practical part are shown algorithms and examples of programming for the fifth and sixth grade of primary school are presented through the curriculum, using a visual programming tool, BBC micro:bit. In the end, the conclusion follows.
