Abstract
Mathematical reasoning and scientific rigorous thought gives the student the possibility to understand other disciplines and look into problems related to nature, life and society, contributes to building and developing the ability to work in an organized and at a sustained pace, enhancing insight and spirit of investigation. At the object of Mathematics, the set theory and mathematical logic elements bring variety in building the concept of natural number, operations with natural numbers and in solving problems, reanimating the lesson and, therefore, making the path to skills’ formation safer and more pleasant. The article is part of our graduation paper and approaches aspects related to the use and integration of set theory and mathematical logic elements in lessons of Mathematics, which will lead to the efficient learning of mathematical notions and problem solving and, by this, to the school progress of primary school students.
Key words: set theory, mathematical logic, research, creativity, experiment
