The article explains the content, structure of abbreviations, key components. "STEM". The history of the development of the" STEM " education is divided into three periods. First of all, Steam (science, technology, engineering, art and mathematics) -appeared in 1990; the second - strem (science, technology, robotics, engineering and mathematics) - was implemented in 2000, and the third stage-2016, the stream is based on the fact that art Science is planning work on artificial intelligence. It is an integrator of the four components of the STEM. The article describes the effectiveness of the components c-science, scientific understanding (science), T – technology (technology), Electronic engineering (engineering), m – mathematics (mathematics) in the organization of the educational process in primary classes. Also in the article we offer the rules for completing the "STEM" tasks. These are: training, setting complex goals, analysis, choice, self-management, personal qualities, trajectory. The main attention is paid to the creative self-management of students using the "STEM" tasks.
