We consider it necessary to enhance non-formal education for solving motivational problems of teaching mathematics. The core of non-formal educational process consists of giving additional stimuli and meanings to performing learning tasks and to envelope the learning cognition into such forms of implementation in order to make them more attractive to the learners and conform to their inner aspirations. Various organizational forms and methods of teaching mathematics on the basis of informational and communicational technologies including seminars, workshops, thematic educational Webquests, case-method, computer educational business games, etc. serve as the instruments of non-formal mathematical education organization.
