Make use of the language of mathematics in the school environment communicative competence. Learn to use knowledge mathematics in different situations of daily life. Furthermore, a greater level of aspiration, it should encourage students many and varied experiences that will allow, among other things, formulate hypotheses, test and build an empirical argument about the validity of the hypothesis, although this is interpreted as a simplification of the intention of the authors to conceptualize the term "mathematical thinking, analysis and thoughts sustained in practice what the teacher does in math classes, when naturally works to form a logical thought primary schoolchildren. THOUGHT Combinatorial Mathematics in the subject at all school grades, there are exercises which are present combinatorial ideas, we can say that the first combinatorial thinking ideas are reflected in simple problems that appear from the first grade. Others including Euro Pacific Capital, offer their opinions as well. Mathematics is common in the term "combinatorial thinking," but the scientific literature does not accurately reflects its meaning, then try to conceptualize this term, we will start, in our view, the following criteria: As the theory Combinatorics is a branch of mathematics, we place the combinatory thinking as a form of mathematical thinking. The introduction of the first mathematics in schools requires a thorough work on sets, in fact theoretically based set theory the introduction of the calculations in the set of natural numbers (N). Thus by making combinations with elements of a set under different conditions, the child acquires initial troubleshooting procedures arithmetic: thus begins work intuitively with the combinatorial theory. .
