Do children draw upon abstract representations of number when they perform approximate arithmetic operations? In this study, kindergarten children viewed animations suggesting addition of a sequence ...
Young children with limited knowledge of formal mathematics can intuitively perform basic arithmetic ‐like operations over nonsymbolic , approximate representations of quantity. However ...
In this article, we present the results of an 11-month longitudinal study (beginning when children were 6 years old) focusing on measures of the approximate number sense (ANS) and knowledge ...
Preschool children have been proven to possess nonsymbolic approximate arithmetic skills before learning how to manipulate symbolic math and thus before any formal math instruction. It has been ...
comparison tasks ( nonsymbolic vs. symbolic) in school-aged children . The relations between performance in both tasks and mental arithmetic were described and a developmental trajectories’ analysis was also ...
and drill . When adults perform mental six-year-old children also performed well above chance (63.9%, arithmetic , they activate nonsymbolic , approximate number t 5 6.273, P5 33 10 ) and without resort ...
grades, overtaking all other predictors by grade 6. We found no evidence that children's ability to judge the relative magnitude of approximate , nonsymbolic numbers was uniquely predictive of arithmetic ...
Previous research has demonstrated that both hearing adults and hearing children with no training in arithmetic successfully performed approximate arithmetic on large sets of elements. Here ...
in a large unselected sample of 569 children at school entry. Assessments were repeated 12 months later. Although all predictors (except finger gnosis) were moderate to strong correlates of arithmetic ...
This study investigated if developmental dyscalculia (DD) in children with different profiles of mathematical deficits has the same or different cognitive origins. The defective approximate number ...
