The article reveals the essence of the concept of «task–clone»,we attempted to define the term. Under tasks-clones we understand the tasks, identical in complexity method solutions, theoretical basis, equivalent or similar in difficulty, different numeric data symbols, the location of objects, names non-mathematical objects. The main didactic function of the «tasks-clones»is an organization of knowledge control. In addition, the task-”clones” promotes the formation of mathematical skills. We identified the main techniques of cloning tasks: the variation of numerical data, symbols, locations of objects, changes in non-mathematical objects in the tеxt of the task. Moreover, these changes should not lead to more difficult computations, to the particular case, in which the basis for decisions changes.
