In the modern world, algorithmics is becoming on a par with school arithmetic, because the basic programming elements mastered by a preschooler will accompany him throughout his life because of global digitalization. The article describes the world practices of teaching algorithmics to children, the pros and cons of various techniques are noted. Special attention is paid to the textless educational programming environment PiktoMir, the experience of organizing and conducting systematic propaedeutic courses of algorithmics and programming for preschoolers and junior high school students is described. The necessity of demonstrating feedback between a computer and a robot to children is described. The authors proposed a solution consisting in adding a new robot to the PiktoMir environment that answers commands-questions. Conclusions are drawn about the direction of further research, in particular, about the need to increase the involvement of children in the process of implementing the program by a robot.
