A importância da compreensão numérica para a matemática no ensino fundamental

Abstract

The discipline of Mathematics is still predominantly based on the exercise paradigm. Without having an understanding of the concepts and properties of mathematics objects, some basic education students are able to memorize and manipulate symbols, but without attributing meanings, even when it comes to basic operations. Therefore, the present study has as a problem question: "To seek to understand which behaviors indicate understanding of basic operations using numbers, and what type of problems should compose the activities for the development of these behaviors during basic education.". Faced with the exposed problem and aiming to contribute with a proposal for alternative approaches, we will seek to identify networks of concepts and competences for numerical understanding in students at different levels of development in Elementary School. Thus, we propose to insert games adapted for the processes of teaching and learning mathematics, here, specifically, we will exemplify an approach for didactic intervention aimed at developing skills to compose and decompose numbers, an important behavior for numerical understanding.
