Not all students in early grades develop efficient strategies for solving subtraction tasks. In this paper, we examine subtraction teaching in the 1--20 number range. We analyzed two first-grade lessons addressing similar subtraction tasks, using variation theory to identify what aspects of the content were foregrounded in the teaching. The…

Early critical thinking and sustainability awareness development is crucial for equipping future generations to handle global issues in an increasingly complicated and interconnected society. This study examined how 9-year-old primary school students applied their knowledge through a collaborative Mystery assignment, demonstrating a Thinking Skill…

In recent years, there has been considerable growth in evidence that open-ended, challenging, and autobiographical tasks may provide better opportunities to evidence how young children exhibit metacognition and self-regulation. This research examines possible differences in children's metacognition and self-regulation between two ecological valid…

There is growing evidence that the ability to perceive structure is essential for students' mathematical development. Looking at students' structure sense in basic numerical and patterning tasks seems promising for understanding how these tasks set the foundation for the development of later mathematical skills. Previous studies have shown how…

The purpose of this research was to explain why many people do not like mathematics and find it difficult because it is difficult to understand or because a teacher they had did not give the appropriate weight. The methodology used in this research was the quantitative method. The sample was collected through electronic questionnaires involving…

Cover-copy-compare is a self-management intervention strategy developed to improve students' academic performance, particularly in spelling. In academic intervention research, it is often assumed that students are completing the intervention as intended, yet this is seldom examined during intervention implementation or subsequent data analysis.…

In this paper, the multidigit arithmetic-related strategy adaptivity, strategy flexibility and solution accuracy of Danish compulsory school students is examined. Participants, 749 grade three, 731 grade six and 818 grade eight, were drawn from twenty demographically different schools. Drawing on a tri-phase assessment tool, each student completed…

This study examines the solutions of 34 kindergarten children as they create equal groups from n bottle caps, where n was equal to 8, 9, 22, and 23. For each n, children were asked to find as many different solutions as possible. The number of solutions they found, i.e., children's fluency, as well as the strategies used to create equal groups,…

Repeating patterning proficiency predicts students' later mathematical proficiency. A comparative multi-case design enabled the present study to compare patterning success and strategy use for repeating patterns of 75 Norwegian 6-year-old grade 1 students. We provided the students with duplicate, extend, transfer, and unit isolation activities in…

The learning of basic facts, or the sums and products of numbers 0-10 and their related differences and quotients, has always been a high priority for elementary school teachers. While memorization of basic facts has been a hallmark of elementary school, current recommendations focus on a more nuanced development of fluency with these facts.…

Spatial ability is a significant component of mathematical ability and a foundation for children to master mathematical knowledge. Although many studies have confirmed that technology can enhance children's learning, few have explored the use of technology in the area of children's spatial learning. In this study, we adopted a paradigm for…

Background/Context: The COVID-19 pandemic disrupted family life in myriad ways, including increasing family stress and reducing access to early care and education experiences. Such factors suggest that children's early learning and development may have been negatively impacted, which would have long-term implications for necessary school support.…

Students with mathematics difficulty, especially students with disabilities and emergent bilinguals, require careful consideration during word-problem instruction. Word problems that include relational terms such as more but are not easily solved using the implied operation (i.e., addition) can be particularly challenging. First, we summarize a…

Instructional routines, like "Number Talks" and "Notice and Wonder," engage students in doing and then talking about their mathematical thinking. Number Talk routines are short mathematical discussions where students mentally solve and share the strategies they used to make sense of the problem. In comparison, the Notice and…

This case study was undertaken to characterise the interventions made by a kindergarten teacher during a multiplicative structure problem-solving lesson. The study findings show that when she realised the children were having difficulty, she provided assistance to enable them to find the right answer. When the children gave an incorrect response,…
