Resumo: According to the majority of educator s elementary school students show difficulties in learning complex mathematic concepts, such as fractions. Such results urgently recommend the development of new teaching methodologies able to help students to overcome their difficulties. Behavioral analyst researchers have been making use of the stimulus equivalence paradigm in order to teach a mathematical repertoire. This paradigm allows to account for the emergency of new behaviors from other previously instructed, and that happens when different stimulus classes are made to be equivalents. Based on this paradigm point the present work elaborated and tested a procedure for teaching fractions using the MESTRE (GOYOS, ELIAS & RIBEIRO, 2005) software as a tool. Three stimulus classes were used: dictated proportional fractions (A), pictorial fractions (B) and printed proportional fractions (C), all of them with values lower than 9.Participated of the study two children age 9, in the 3rd grade of two private elementary schools of São Paulo city. The teaching Schedule was applied over two participants with nine years old, students of the third grade in private educational institutes (Sao Paulo South Square). Design involved pre-tests, teaching phase and tests for emerging relations and generalization test. The AB and BC relations were taught; relations BD, CB, AC and CD were only tested for emergency of other relations (subjects should read printed proportional fractions). Generalization was tested submitting students to fractions not previously taught. Part of these had denominators which had not been employed during the training phase. Results indicated that not trained relations BD, CB, AC and CD (where subjects should read printed proportional fractions) emerged showing that stimulus classes A, B and C became equivalents. Besides students proved to be able to read fractions without explicit training, making evident that the educational program was effective and that the equivalence paradigm is a helpful tool the fill the gaps left behind by ongoing educational practices
