Although many U.S. children can count sets by 4 years, it is not until 5½--6 years that they understand how counting relates to number--that is, that adding 1 to a set necessitates counting up one number. This study examined two knowledge sources that 3½- to 6-year-olds (N = 136) may leverage to acquire this "successor function": (a)…

Susperreguy, María Inés; Di Lonardo Burr, Sabrina; Xu, Chang; Douglas, Heather; LeFevre, Jo-Anne – Child Development, 2020
This study investigated the longitudinal associations between children's early mathematics and their home numeracy environment (HNE). Chilean children from families who varied widely in socioeconomic status were assessed at the beginning and end of prekindergarten in 2016 (N = 419, M[subscript age] = 4:7 [years:months]), and at the end of…

Koponen, Tuire; Eklund, Kenneth; Heikkilä, Riikka; Salminen, Jonna; Fuchs, Lynn; Fuchs, Douglas; Aro, Mikko – Child Development, 2020
This study examines the core predictors of the covariance in reading and arithmetic fluency and the domain-general cognitive skills that explain the core predictors and covariance. Seven-year-old Finnish children (N = 200) were assessed on rapid automatized naming (RAN), phonological awareness, letter knowledge, verbal counting, number writing,…

Schneider, Michael; Merz, Simon; Stricker, Johannes; De Smedt, Bert; Torbeyns, Joke; Verschaffel, Lieven; Luwel, Koen – Child Development, 2018
The number line estimation task is widely used to investigate mathematical learning and development. The present meta-analysis statistically synthesized the extensive evidence on the correlation between number line estimation and broader mathematical competence. Averaged over 263 effect sizes with 10,576 participants with sample mean ages from 4…

Barner, David; Alvarez, George; Sullivan, Jessica; Brooks, Neon; Srinivasan, Mahesh; Frank, Michael C. – Child Development, 2016
Mental abacus (MA) is a technique of performing fast, accurate arithmetic using a mental image of an abacus; experts exhibit astonishing calculation abilities. Over 3 years, 204 elementary school students (age range at outset: 5-7 years old) participated in a randomized, controlled trial to test whether MA expertise (a) can be acquired in standard…

Peer reviewedBrainerd, Charles J. – Child Development, 1976
It is argued that Macnamara's criticisms of Piaget's theory of number do not lead to Macnamara's conclusions about arithmetic instruction. These conclusions appear to be based on misconceptions about logic and logical theories of number. The misconceptions are discussed and an empirical rationale for the conclusions about arithmetic instruction is…
