The present article is related to the role of representational tools in teaching and learning of mathematics. It aims to present education practices with the aid of visualizations in order to reduce the difficulties on fractions of the students of the 5th and 6th grade of elementary school. The research emphasizes visual ways of thinking and visualization of fractions through representational tools, use of experiential activities and activities carried out on electronic platforms. The results of the research indicate that students, after instructive interventions with the use visual way of thinking and visualization of fractions through representational tools, performed better on fractions. On the other hand, the phenomenon of compartmentalization of the students’ solutions of tasks on fractions has been observed and analyzed.
