Abstract
Este estudo buscou investigaro desempenho de 67 alunos surdos dos três primeiros anos do Ensino Fundamental, usuários de Libras -Língua Brasileira de Sinais, na realização de cálculos de adição e subtração, a fim de identificar se o uso de uma língua de modalidade visuoespacial interfere na maneira de executar tais cálculos.Objetivou-se descrever as principais estratégias utilizadas pelos estudantes e verificarerros frequentemente cometidos, relacionando-os às estratégias empregadas. As análises, quantitativas e qualitativas, revelaram que houve progressão acadêmica com a escolaridade e maior dificuldade na resolução dos cálculos de subtração.Identificou-se o uso de formas particulares na resolução de cálculos que podem ser atribuídas à modalidade visuoespacial da Língua de Sinais: algoritmos sinalizados. Essas estratégias são oriundas de uma forma de representar, contar e operar com os números, por surdos usuários de Línguas de Sinais, trazendo em si uma característica própria que as distinguem das formas de operar com os dedos, por ouvintes
The aim of this study was to investigate the performance of 67 deaf students from the first three years of Elementary School, users of Libras -Brazilian Sign Language, in doing calculations of addition and subtractionto identify whether the use of a visuospatial language interferes in this way of achievement.Themain strategies used by students were described, mistakes frequently done were identified and related to the strategies employed. Both, quantitative and qualitative analysis,revealed there was an academic progression with schooling. It was identified theuse of particular forms in the resolution of calculations that can be attributed to the visuospatial modality of Sign Language: signed algorithms. Such strategies come from the way deaf users of Sign Languages represent, count and operate with numbers. They bring characteristics of their own, that distinguish them from the ways listeners operate with their fingers
