Understanding the decimal positional systemis fundamental to the construction of logical mathematicalknowledge. Throughout history, mankind has conceivedgreat inventions, among them the playful soroban the Japanese abacus. In the Land of the Rising Sun, schools had as its motto: reading, writing and arithmetic, and the latter was synonymous with soroban. After the invention of the electronic calculator, there was a competition between soroban and calculator, and the first won, proving that the Japanese abacus is a effective and fast, or more, as the new technology available. Through the soroban all the fundamental basic operations of arithmetic can be performed. This work aims to show the potential of this tool, not only as a concrete and manipulable material, but as support to the understanding of addition, subtraction, multiplication and division operations, as well as their properties. Further, there is a short account of the experience and analysis of the use of soroban as support to 7th grade students who failed in 2013. In teaching-learning process, using the principle that the teacher must seek new knowledge to his/her professional growth, students which are the focus, can also grow as the teacher believe, dare and try new materials and methodologies
