This paper belongs to a field of research that has appeared comparatively recently, namely, the study of mathematics competitions. The paper utilizes historical-theoretical methodology and is devoted to changes in the way in which mathematics competitions have been conducted in Russia in recent decades. Mathematics competitions, like mathematics education as a whole, are seen as part of a social process, and changes in them are seen as expressions of new social needs and possibilities. The analysis of the system of competitions, as it evolved in the USSR, and the literature devoted to them, makes it possible to identify certain challenges recognized by the mathematics community. In this paper I discuss examples of new competitions that have emerged to address these challenges. It is noted that new types of competitions have emerged, including team competitions and competitions involving mass participation by students. Also discussed is the emergence of new competitions with subject matter closer to that of ordinary school mathematics than that of old, traditional competitions. An analysis of the situation in Russia reveals the existence of a significant group of mathematics educators, parents, and children interested in the development of mathematics competitions. Also, in the paper I call attention to certain questions that I consider worthy of further study. [ABSTRACT FROM AUTHOR]

The nature of the area of mathematical competitions as a design science is considered, historical roots of mathematical problem-solving competitions are traced, the complementary aspects of mathematics as theory building and as problem solving are touched upon in relation to the practice of competitions. Two historical figures, Euler and Erdős, emerge, and the appropriateness of many of Euler's mathematical ventures are seen as role models for competition mathematics as first put into practice in mathematical competitions towards the end of the nineteenth century. Distinctions and definitions are made, a venture into identifying competition syllabi and the principal types of reasoning employed in solving competition problems is explored, and a description of the many different types of competitions is considered. Interaction between the field of mathematics itself and problem-solving competitions is briefly explored, as are the possibilities that open when competitions and their access to huge amounts of data, both national and international, are taken into account in research belonging to mathematics education. Finally, the range of topics addressed in this special issue of ZDM is covered, along with some possible conclusions relating to the components of the overview. [ABSTRACT FROM AUTHOR]

In this paper we make overview of the additionalmathematical education for pupils in Lithuania. Mathematical contests and olympiads, clubs and schools,lectures of professionalmathematiciansand other activities are discussed including the history and contemporary condition of all these activities. We give special credit to the enthusiasm and work of the educators from schools and university and scientists in the field of additional education.

The 'Math by the Month' activities are designed to engage students to think like mathematicians. The activities allow for students to work individually or in small groups, or they may [...]
