This research aims to analyze the meanings attributed by students of the 6th year of Elementary School on the equal sign in the resolution of addition sentences. In order to do so, we take as a theoretical-methodological reference studies that discuss the meanings of the equal sign in an operational and relational perspective. Data collection was performed using a diagnostic test with five questions with addition sentences. The test was applied in two classes of the 6th year of Elementary School in two private schools, one located in Olinda – PE and the other in Recife – PE. 19 students participated in the research. The test results show that most students, who made mistakes in solving sentences, presented the notion of the operational equality sign, as they understand that the equal sign is a direct indication of the result of an operation, that is, “operation = result". For those who attributed the meaning, in a relational perspective, to the equal sign, we can identify that most of them used arithmetic procedures both to determine the unknown term and to determine whether the sentence would be true or false, demonstrating dependence on the performance of arithmetic operations. involved in solving addition sentences.
