Our work investigated how six primary school students used a non-traditional method for adding and subtracting: the ABN method, a Spanish acronym for Open (method) Based on Numbers. Commognitive theory [Sfard, A. 2008. "Thinking as Communicating: Human Development, the Growth of Discourses, and Mathematizing." New York: Cambridge…

Building students' confidence and conceptual understanding early sets a solid foundation for reasoning and exploration. "Nurturing Math Curiosity With Learners in Grades K-2" offers educational tools and strategies teachers can use to integrate mathematical argumentation in early elementary classrooms, allowing space for students'…

Background or Context: Teachers knowing their students is consequential for students' participation and learning. Evidence in mathematics education points to the ways that knowing the details of students' mathematical thinking supports teacher and student learning. What it means to know students and what teachers learn about their students are…

Mathematical problem solving remains a struggle for many students today (Celebioglu et al., 2010; Englard, 2010; Gavaz et al., 2021; N. H. Lee et al., 2014; Yeo, 2011). Though intervention studies have reported measured impact on improving students' problem-solving abilities (Gavaz et al., 2021; Gidalevich & Kramarski, 2019; N. H. Lee et al.,…

The purpose of this qualitative phenomenological research study was to explore and illuminate lived professional developmental experiences and personal perspectives of a select group of K-2 mathematics teachers. According to Creswell and Poth (2017), researchers collect and analyze data from people who experience a phenomenon to describe "the…

Adaptive teachers use student data to guide instruction. Learn about using an anecdotal record form to support adaptive teaching. In this article, the authors describe how teachers can use learning trajectories to make adaptive decisions to meet the needs of their students. They provide an example using the U .S. Math Recovery Council's learning…

Although children learn more when teachers gesture, it is not clear "how" gesture supports learning. Here, we sought to investigate the nature of the memory processes that underlie the observed benefits of gesture on lasting learning. We hypothesized that instruction with gesture might create memory representations that are particularly…

The results of this study revealed students' solution strategies progressed from inefficient strategies e.g., counting on fingers to more efficient strategies with mathematical connections. These findings should enable educators to gain more insight to use Number Talks to help student develop computational fluency with numbers.

This study aims to examine whether a maths-unrelated reading intervention can improve children's mathematical performance and to compare the effects of maths-related and maths-unrelated reading interventions. Furthermore, this study examines whether the effects of reading interventions are moderated by individual differences, including gender,…

The purpose of the study was to observe the understanding and motivation of second-grade Tier III students' achievement in skip-counting patterns by implementing music and non-music learning activities. The case study was performed using a qualitative design. A pretest-posttest and repeated measures design was used to analyze and triangulate the…

The perception and manipulation of spatial information are essential for mathematical learning, and research highlights gender differences in spatial abilities. The present study contributes to the question of whether these differences are evident at earlier ages and how they interact with task complexity in mental rotation. We developed the…

We share results from a one-year early algebra classroom intervention. One kindergarten, one first-grade, and one second-grade classroom participated in the intervention and three classrooms of the same grade levels served as control sites. The intervention addressed the structure of even and odd numbers, mathematical equivalence and equations,…

This research aimed to (1) study the factors affecting the development of mathematics achievement of second-grade students in Qinhuang Town Primary School, (2) develop an instructional model based on Gardner's Multiple Intelligence Theory, (3) compare the mathematics achievement of second-grade students before and after using an instructional…

Background: Early numeracy interventions including basic arithmetic are crucial for young students at risk for early mathematics difficulties (MDs), yet few studies have evaluated numeracy interventions in second grade with a randomized controlled design. Aim: This pre- and post-test randomized controlled study evaluated the effects of an…

Professional learning that includes coaching is an effective method of supporting teachers to make changes to their teaching practice. This article provides an overview of the initial in-situ professional learning and coaching in a primary school in Western Sydney facilitated by a Mathematics Teaching Educator. In this article I present the…
