This article is written on the basis of the analysis of scientific and methodological literature over the past two years and the personal experience of the authors of conducting mathematical disciplines with cadets and full-time students using distance learning technologies. The purpose of this article was to substantiate the relevance and significance of using a set of individual homework assignments containing applied tasks of an economic orientation for generalizing the material and acquiring the skill of synthetic activity. The study was conducted for four semesters in the classroom in the disciplines of the mathematical cycle with students of economic specialties. As a result of the work carried out, the authors were able to identify and analyze the most typical problems associated with the mathematical training of future economists. One of the ways to solve them is to use workbooks with tasks of economic content, the peculiarity of which lies in the structure of construction: around the central core (which is chosen as one of the basic economic concepts), several tasks are formed that reinforce various topics of the discipline being studied.
