Early Number Development in Children with Special Needs: Correspondence, Classification, Comparison and Seriation

Abstract

Early number skills/concepts mean the skills and concepts that must be gained beforenumber acquisition. We can get those prerequisite skills from the theory of Piaget’s Cognitive Development; correspondence, classification, comparison and seriation. Theseskills, which are essential for all children, take a much larger place in the lives of childrenwith special needs who have difficulty in understanding abstract concepts. The aim of thisreview study is to give information on the concepts of correspondence, classification, comparison, and seriation studied before the acquisition of the number concept and investigatethe research on the concepts and skills before number acquisition in children with specialneeds. This review study was conducted with 22 studies, which met the inclusive criteria.The studies were examined in terms of skills, design, and interventions. Results showedthat classification and seriation were the most studied skills in the studies and effectivepractices were used in teaching early number skills or concepts. These effective practiceswere explained and implications for future research were discussed
