Children's sense of numbers before formal education is thought to rely on an approximate number system based on logarithmically compressed analog magnitudes that increases in resolution throughout childhood. School-age children performing a numerical estimation task have been shown to increasingly rely on a formally appropriate, linear representation and decrease their use of an intuitive, logarithmic one. We investigated the development of numerical estimation in a younger population (3.5- to…

Varieties of quantity estimation in children.
The findings demonstrate that estimation of numerical and non-numerical quantities is based on different processing strategies and follow different developmental trajectories.
Linear Numerical-Magnitude Representations Aid Children’s Memory for Numbers
The results indicated that children’s representations vary from trial to trial with the numbers they need to represent and remember and that general strategy-choice mechanisms may operate in selection of numerical representations, as in other domains.
Representational change and strategy use in children's number line estimation during the first years of primary school
This study has identified that children employ variable strategies when completing numerical estimation, with levels of strategy advancing with development, which highlights the limitations of any regression modeling approach.
In the current study, three possible interpretations of children’s number line estimation (NLE) performance were examined for appropriateness and possible correlates of performance were tracked over
A Longitudinal Study of Number Line Estimation in Young Children
The development of numerical representations plays a central role in a child's mathematical abilities. Previous studies have reported that children's numerical representations shift from logarithmic
Representation of numerical and non-numerical order in children
Developmental change in numerical estimation.
The proportional account explained estimation patterns better than the logarithmic-to-linear-shift account for all age groups, at both group and individual levels, and contribute to the understanding of the nature and development of the mental representation of number.


Development of numerical estimation in young children.
Individual differences in number-line estimation correlated strongly with math achievement test scores, improved estimation accuracy proved attributable to increased linearity of estimates, and exposure to relevant experience tended to improve estimation accuracy.
Individual differences in non-verbal number acuity correlate with maths achievement
There are large individual differences in the non-verbal approximation abilities of 14-year-old children, and that these individual Differences in the present correlate with children’s past scores on standardized maths achievement tests, extending all the way back to kindergarten.
Developmental and individual differences in pure numerical estimation.
Developmental and individual differences in pure numerical estimation, the type of estimation that depends solely on knowledge of numbers, were examined and all types of estimation skill were positively related to math achievement test scores.
Development of Numberline and Measurement Concepts
In a two-part study, children in Grades 1 through 3 were given a set of numberline estimation problems and a set of similar numberline estimation problems that were to be solved using specially
Development of Number Line Representations in Children With Mathematical Learning Disability
The central executive component of working memory contributed to across-grade improvements in number line performance and to group differences in this performance.
Preschoolers' Magnitude Comparisons are Mediated by a Preverbal Analog Mechanism
The hypothesis that adults and children share preverbal, analog representations of magnitude is supported, because performance on posttests of verbal counting ability was variable, but did not predict performance on the numerical discrimination task.
Development of Elementary Numerical Abilities: A Neuronal Model
The computer simulations account for several phenomena in the numerical domain, including the distance effect and Fechner's law for numbers, and demonstrate that infants' numerosity detection abilities may be explained without assuming that infants can count.
Preschool children's mapping of number words to nonsymbolic numerosities.
Findings provide evidence that large, approximate numerosity representations become linked to number words around the time that children learn to count to those words reliably.

Children's Knowledge of Teen Quantities as Tens and Ones; Comparisons of Chinese, British, and American Kindergartners.
Three studies were conducted to examine the effects of individual differences and language differences on children's understanding of teen quantities (11 < n ≤ 19) as counted cardinal tens and ones
