Peoples of the North, for centuries developing in the enormous ice cold region, severe climatic conditions of the Arctic, have not only a peculiar tenor of life, but also thinking, a certain knowledge of environment inherent in them. In this context the systematization of mathematical knowledge and representations of the northern people of Russia, from the point of view of elementary questions of development of concepts of number and numbering of numbers, original terminology, emergence of measures as the significant social experience of the nomadic people adapted for transfer from generation to generation is necessary for realization of an ethnocultural and national and regional component of training. The problem of studying the national mathematics of indigenous ethnic groups of the North - Yukaghirs is considered in this article. The main content of research makes the analysis of historical, ethnographic scientific literature, folklore materials. Systematic inclusion in the content of the mathematical education the ethnomathematical materials, tasks on folklore, historical and local history material of the native people promotes the development of pupils' interest in mathematics, gives teacher the opportunity to use them as the means of educational cognitive activity on mastering the mathematical knowledge. Using at lessons the suitable examples from the activity of the northern people, studies of local lore promote the formation of ability to investigate mathematically the phenomena of the environment and to put the mathematical knowledge into practice. The systematization of the national mathematics of Yukaghirs, and also a selection of author's tasks on historical, folklore and local history material of Verkhnekolymsky and Nizhnekolymsky uluses of the Republic of Sakha (Yakutia) is presented.
