This study aimed to investigate the knowledge of teachers who teach mathematics on rational numbers. We focus on this type of numbers because it is the content of the 5th and 6th grades of Elementary School. We take as a theoretical basis the Mathematical Knowledge for Teaching (MKT). For the production of data, we used questionnaires and had as participants teachers of Pedagogy and Mathematics. We categorize the productions according to our theoretical framework: Content and Curriculum Knowledge (CCK), Knowledge of Content and Students (KCS), Horizontal Content Knowledge (HCK), Knowledge of Content and Teaching (KCT), Common Content Knowledge (CCK) e Specialized Content Knowledge (SCK). We conclude that there are gaps in the mathematical knowledge of the participating teachers. Thus, we point out the need for continuous teacher training that includes rational numbers.
