In the literature on numerical cognition, the presence of the capacity to distinguish between numerosities by attending to the number of items, rather than continuous properties of stimuli that correlate with it, is commonly taken as sufficient indication of numerical abilities in cognitive agents. However, this literature does not take into…

The aim of this study was to develop an instrument for assessing sixth-grade students' number sense skills in fractions and decimals. This study was conducted on 452 sixth graders (10-11 years old) from the western region of Turkey. The construct validity of the number sense test (NST) was examined via exploratory factor analysis (EFA) and…

Mastery of the cardinality principle (CP) is foundational for children's mathematical development. Children's age and subitizing and counting skills contribute to their CP acquisition. This study aimed to investigate the effectiveness of different types of instruction for supporting 3-4-year-olds' CP development and its interplay with child…

Recently, there have been calls to build a more inclusive knowledge base of the home numeracy environment (HNE) by diversifying the populations in our descriptive research. Given that Latine children are the fastest-growing population in the U.S. it is of the utmost importance to include Latine families and children in these efforts. The present…

When children are aged around 2 years, many of the early foundations of mathematical skills are developing. Understanding this is important to shed light on theories of mathematical development. Nevertheless, little research has investigated 2-year-olds' early mathematical abilities, with most research focussing on either infants (aged 0-1 years)…

The same and different routine offers an opportunity to build a strong foundation for future grades while also deepening the experiences of prekindergarten and transitional kindergarten students. Students have opportunities to make sense, share ideas, and engage in the ideas of others. We conjecture this type of experience supports students and…

This paper reports on our study of the effectiveness of the course instruction in the numeracy course 'Numbers for Life', offered at McMaster University, Canada, and taught by one of the co-authors. In this course students explore the ways to reason with numbers in a variety of contexts important not only for their individual lives and their…

Background/purpose: Mathematical literacy is an important ability that students must acquire, but several studies indicate that Indonesian students' mathematical literacy remains low. Therefore, this study aims to (1) test the effectiveness of CTL assisted by Articulate Storyline in improving students' mathematical literacy and (2) analyze the…

Background: Despite its potentially significant functional and emotional impact, acalculia is still too rarely assessed and managed by speech and language therapists. Research on the rehabilitation of numerical transcoding remains scarce in the literature and, despite positive results, presents a low level of evidence. Aims: The present study aims…

The aim of this study is to determine the number sense skills of preschool (Kindergarten) children. In the study, survey design, one of the quantitative research methods, was used. The study group consists of a total of 114 children attending all the kindergartens (5 kindergartens) in the city center of Tunceli in the 2020-2021 school year. The…

Taking into consideration that young children engage with mathematics outside of the preschool classroom, this study focuses on adults' awareness of numerical ideas raised by young children without and with adult involvement. Ninety adults in Israel, the majority of whom were parents or grandparents of children aged 3-6 years, participated in this…

We investigate the effects of private schools on reading and numeracy scores using rich population data. Conditional on lagged test scores and narrowly defined neighborhood indicators, Catholic and non-Christian faith private schools on average raise test scores by 0.18 standard deviation or more relative to the average public school, while…

Mathematical literacy, quantitative literacy, numeracy, matheracy, disciplinary literacy, and content-area literacy are among a plethora of terms used to link mathematics and literacy. In addition to this abundance of terms, the content of the terms is not precise, and in some cases the terms are used interchangeably. I delve into this landscape…

Background: While students possess procedural knowledge associated with engineering calculations and calculus, they often exhibit a disconnect between the conceptual meaning of mathematics and the problem being solved. This conceptual understanding of what mathematics "says" is defined by the theoretical framework of numeracy. Many…

Findings from previous work show that caregivers' math anxiety moderates the positive association between caregiver-child math activities and child math outcomes. Most of this research, however, has focused on elementary school children, primarily White populations, and used mainstream measures. The present study examined the associations between…
