The article describes the experience of developing and conducting a lesson-game in informatics, in which, in the form of a team competition, students' initial knowledge about the computer, types of information, actions with information is repeated and consolidated, and logical thinking is also activated. All stages of team game are presented with the formation of universal educational actions in students and the achieved subject learning results. The content of the lesson is structured in such a way that, after passing all competitions, students will be able to consolidate subject competencies and continue to develop meta-subject competencies. The course of the lesson is based on the fact that students take turns performing tasks and working in a team. Each stage of the lesson is accompanied by a demonstration of tasks and questions on an interactive board with musical accompaniment, which ensures a positive mood for the game. The jury assigns points to teams using score sheets. At the end of the lesson-game, the jury announces the results, and the teams are awarded places in the competition. The teacher prepares award materials in the form of certificates and medals in advance.
