Abstract

We present research into how a group of 9 students with Down syndrome perform subtractions and additions. This descriptive and qualitative study uses previous research conducted in this area on people without disabilities to detail the strategies, procedures and errors involved. The data were gathered from algorithms performed on a digital board, which allows for the numbers used in the operations to be represented using balls. The results show that students with Down syndrome use the same strategies and procedures as normal students, though none of the subjects operated on a completely abstract level. The use of fingers or concrete representations (balls) appears as a fundamental process among these students. As for errors, these vary widely depending on the students, and can be attributed in their majority to an incomplete knowledge of the decimal number system.
