Mathematical knowledge and language in deaf students: The relationship between the recitation of a numerical sequence and Brazilian Sign Language proficiency

Abstract

Abstract The present study investigated recitation skills, constitutive of the number concept, and their relationship with language skills in the Brazilian Sign Language. Different levels of numerical sequence recitation were identified in 1st to 3rd grade deaf students attending a bilingual Elementary School (Brazilian Portuguese and Brazilian Sign Language), as well as the association between numerical recitation and schooling. The ability to enumerate was associated with specific levels of receptive and expressive language in Brazilian Sign Language.
