The formation of comprehensive and in-depth notions of objects and phenomena in the world can be achieved when the mastery of knowledge and skills is carried out in a system realized in the context of integration of different scientific directions. One of the main issues in modern education is related to the contradiction - on one hand between the need to form the skills necessary for the orientation and adaptation of the personality in the dynamics of the globalizing world and on the other - the education which is largely based on unilateral acquiring of knowledge and skills within the different subject areas. This influences the development of a worldview and the formation of an adequate attitude towards the problems under consideration and the world as a whole. The knowledge and skills acquired today are often “locked” in the respective direction. The cross-curricular unity in the curriculum is of a recommended nature, but even if it is realized, it does not fully meet the need for a comprehensive and multifaceted consideration of global issues, as a result of which the student not only understands, reflects, but also applies the lessons learned in the process of creating a product - ideal or material. Combining the intellectual nature of the cognitive process with the practice activity are conditions in which the students are highly active and achieve better learning outcomes. Therefore, it is expedient for the different directions to correspond more closely to each other and to carry out effective cross-curricular integration. The concept of applying an integrative approach in the current paper is based on the idea of creating pedagogical conditions for reconciling the goals and expected outcomes of technology and entrepreneurship and natural sciences studied at the initial stage of the primary education. Integration can take place on two levels - knowledge and skills. We believe that the lapbook as an innovative didactic tool contains the necessary potential for effective realization of the educational goals in both directions in terms of achieving the expected results. In the course of its elaboration, new information is acquired in the field of engineering and technology, specific skills underlying the curricula of technology and entrepreneurship programs are developed. At the same time, a number of subjects from the learning content, which are considered from the natural science point of view, are enriched and perceived in a technological way, after which they find place in an attractive book - a lapbook, made by the students themselves. Its utilitarian value is multiplied by the personal contribution to its creation - not only as an object but also as content. The main topics that are of interest to the students are exploring and preserving nature, jobs, modern technical achievements, holidays and customs. As a result of the adequate integration of competences, tailored to curricula, a number of skills are formed, such as: skills for searching on their own, systematization and presentation of information, and application of the lessons learned in a new situation.
