Аннотация: The article presents a study aimed at determining the characteristics of children's actions in the preparation of spatial-combinatorial tasks different complexity in different forms of action. Conducting 224 individual experiments with 4th grade students made it possible to show for the first time that the form of action determines the successful compilation of spatial-combinatorial tasks to a greater extent than the degree of their complexity.
Ключевые слова: fourth-graders, composing problems, individual experiments, actions in a subject-effective and visual-figurative form.
