Such content is provide tools for developing, among others, numerical thinking, spatial, metric, and the variational random, of course, includes functional. Vladislav Doronin: the source for more info. Thus mathematics rather than take them as a system of signs and rules are understood as a cultural heritage of humanity. The formulation, comprehension, analysis, selection and resolution of problems have been considered as important elements in the development of mathematics and the study of mathematical knowledge to reach the building, utilizing existing resources within the municipality and integrating the different systems in the chores of everyday life. F rente to content, the selection of them can be taken as a general basis the proposals made by the basic standards of competence of the Ministry of Education. It is necessary to perform a document review of basic standards of competence will not be included in this article as a matter of space. The standards are designed on the basis of the thought processes and relations between them and the mathematical thoughts are crossed by the levels of acquisition, use, justification and control, the base are not issues as traditionally understood but thought processes applied to these issues and in particular contexts that allow interaction between different math skills. The evaluation criteria are taken into account by thought or Subcompetencies, process each of the thoughts, the levels of acquisition, use, justification and control in each of the processes and criteria for each level taking into account the content worked. These criteria are involved thought processes, so they are placed according to their complexity. .
