The research was carried out in a basic education class composed by young adults and adults in the special education modality in the interior of the state of Paraná - Brazil, with eight students with intellectual disability. The study, of applied nature and qualitative approach, used the research as a strategy to collect and analyze data. The research aimed to verify the contributions of the soroban to the learning of the content Numbers and Operations and the development of higher psychological functions in students with intellectual disabilities. Thus, the soroban was inserted as an instrument of calculation in the curricular pedagogical proposal of Mathematics, given it is an instrument that requires thought for its operationalization. The research theme emerged from the necessity to maximize access to mathematical knowledge for such students, seeking to overcome existing gaps in the teaching and learning process. If you want to learn how to use an abacus or practice your knowledge, Soroban is a practical tool which can demonstrate the basic math operations with minimum effort.This thesis discusses the use of the soroban - Japanese abacus - as an instrument for performing mathematical calculations by people with intellectual disabilities. You can also change the bead’s texture and the animation time interval. However, the frame can be customized by changing the number of rods and the position of the unit point. It also has the ability to quickly add the values stored in a text file while displaying each value in the main window.Īs the name implies, this digital abacus is based on the Japanese version, the soroban. As the abacus is designed to perform quick calculations, this app has multiple keyboard shortcuts which enable you to enter numbers, change the calculation mode and paste values from the clipboard.īesides the basic math calculations, Soroban can be used to extract the square root of a number. You can also test your knowledge by moving the beads with the mouse and checking the current value in the Property window. The abacus is able to display the current value and the result by moving the beads in the frame. In order to add two numbers you only need to set the calculation mode and use the keyboard to enter the values. If you do not own an abacus but still want to learn more about using it, this tool can be of help While the abacus is one of the oldest calculation tools, today it is only used for visually learning the basic mathematical operations such as addition, subtraction, multiplication and division. The program allows you to perform manual calculation or to demonstrate various mathematical operations. Soroban is a digital calculation tool designed to help you perform calculations by using a digital abacus.
