Abstract
The authors of the article justify that in primary education, improving teaching effectiveness and the educational value of subjects, along with other methodological issues, requires the use of integrated connections and approaches known as subject integration. The methodology of integrated lessons ensures interaction between teachers and students at the level of subject relationships, which creates opportunities for joint creativity and self-development of participants in the educational process. It is concluded that this approach helps resolve contradictions within the subject-based system between academic knowledge and its practical application in labor and everyday life.
