Abstract

The use of Balok Pelangi Dienes aims to improve the ability to determine place value for students with learning disability. The ability to determine place value is profoundly needed as prerequisites in the acquisition of other mathematical concepts, such as the operation of addition, subtraction, and others. The type of the research was the experiment using singlesubject research approach with A-B-A design. The subject of the research was elementary school student in grade 5 aged 11 years old. The target behavior research was the increase of ability to determine place value through reading and writing numbers. The data of the research were measured using frequency to identify correct answers on condition of A1 (first baseline), B (intervention) and A2 (second baseline). The results showed that the frequency of student’s correct answers has significantly increased after the intervention. This was proved by the inclination of increased line direction and the small percentage of overlapping data. Therefore, the use of Balok Pelangi Dienes as media can improve the ability to determine place value for students with learning disability.
