To provide a landscape of mathematics activities children experience in U.S. preschool and kindergarten classrooms, we observed time children spent in mathematics activities (and -- as a contrast -- literacy) in 101 geographically diverse early childhood classrooms in seven U.S. states. We also observed what mathematics content, grouping…

Research Findings: The present study analyzes whether child factors are linked to variations in teacher cognitive activation (CA) among individual children in math-related activities within Chinese kindergarten classrooms. The findings show that teachers tend to provide direct CA with high concreteness and that child engagement with tasks is…

This study aimed to investigate the impact of inquiry-based indoor and outdoor mathematics activities on pre-school children's geometric and spatial thinking skills. Thirty-two children between 48 and 66 months old participated in the study. The study employed as a quasi-experimental research model and employed Non-equivalent Control Group Design.…

Counting is fundamental to early mathematics. Most studies of teaching counting focus on teachers observing children count. The present study compares mathematical ideas that 12 PK, transitional kindergarten (TK), and kindergarten teachers noticed from observing their own students count during a classroom session of Counting Collections with ideas…

This study compares mathematics instructional practices in classrooms that do and do not contain students with high-incidence disabilities (HIDs). To do so, we examined a national data set of responses from kindergarten teachers about instructional practices. We do find that in classrooms with students with HIDs, teachers reported different…

This study investigates kindergarten children's mathematics learning with a focus on the role of teachers' mathematics education and readiness beliefs, and home learning environment. Using structural equation modeling to estimate the individual differences in early mathematics learning, data from 5,845 kindergarteners was evaluated. Findings show…

Scaling up educational interventions in the STEM (Science, Technology, Engineering, and Mathematics) field is critical but under-researched. We review and draw implications from a series of studies investigating the long-range impact of an implementation of an early mathematics scale-up model based on learning trajectories. Lasting effectiveness…

This article describes how a teacher in Mexico City worked with two researchers on an instructional design project to help kindergartners become proficient in participating in whole-class mathematical conversations.

This paper focuses on kindergarten teachers' interactions with young children during mathematical learning activities involving the use of digital tools. We aim to characterise the teachers' roles and actions in these activities and extend considerations of teachers' orchestrations current in the research literature with regard to agency and…

Research Findings: We evaluated the fidelity of implementation and the sustainability of effects of a research-based model for scaling up educational interventions. The model was implemented by 64 teachers in 26 schools in 2 distal city districts serving low-resource communities, with schools randomly assigned to condition. Practice or Policy:…

The aim of this study is to analyse how a kindergarten teacher orchestrated a mathematical activity involving a fairy tale. Taking a sociocultural perspective on learning and development, naturally occurring talk-in-interaction has been analysed in order to scrutinise the subtleties of the orchestration. The fairy tale "Goldilocks and the…

This article explores the use of children's photography as a method for conducting mathematics education research with young children. Collected as part of a study focusing on the experiences with measurement children have at the start of schooling, the photographs presented here were taken by children aged five and six years, from two Australian…

"The Zeroing in on Number and Operations" series, which aligns with the Common Core State Standards and the NCTM Standards on Focal Points, features easy-to-use tools for teaching key concepts in number and operations and for addressing common misconceptions. Sharing the insights they've gained through decades of mathematics teaching and research,…
