The relevance of the study is due to the current state of development of scientific fields, the technologization of human life, rapid and barrier-free access to a significant amount of information for preschool children, which determines the need to form adequate ways of its awareness and comprehension, general methods of cognitive activity. The older preschool age 3 6-7 years of children's life - is of great importance in the formation of the cognitive sphere of the individual. In this context, it is important to master all key competencies by the end of preschool childhood, which are formed through the expression of the child's activity in all specifically childhood activities, including educational and cognitive, play, children's experimentation, and others. On the other hand, its formation determines the organic process of preschool maturity at this age and the formation of intellectual readiness of older preschoolers for the conditions of systematic education in primary school. In this aspect, the problem is exacerbated by the unjustified desire of children's parents to prioritize the mastery of the subject content of the basics of science, which does not indicate the optimal overall mental development of senior preschoolers' cognitive activity. Thus, the high level of formation of cognitive activity of senior preschoolers, through playful activities, is recognized as one of the priority tasks of preschool education, as evidenced by the strong public and state interest in meeting the requirements for ensuring the quality of its formation in the modern educational process of preschool education institutions. The importance of this problem is reinforced by the lack of integrity of its generalization in scientific works, which is due to several contradictions: ? between the intensive use of board games in organizing the life of older preschoolers outside the preschool education institution and the lack of proper scientific and methodological support for their use in the educational process. ? between the social request of parents for the formation of intellectual and cognitive readiness of children aged 6-7 years for school and age-related limitations of mental capabilities of their cognitive development. ? between the cognitive potential of modern board games and the general trend of reducing games. Therefore, the formation of cognitive activity of senior preschoolers is a complex problem that requires an integrated approach to its solution.
