Relations of reading and math skills are well-documented. Using open randomized reading intervention data, we examined a reading intervention's impact on math fluency and problem-solving as well as the mechanisms of reading intervention's relation to math fluency. Twenty-eight teachers and 511 first-grade students (82% White, 6% Hispanic, 53%…

Thirty-seven third graders and thirty-two first graders engaged in solving a tangram puzzle in the shape of a fox. They had five minutes to solve the puzzle, and after this time, they received guidance on the particular piece they had difficulties with. Through the lenses of navigating flexible abstraction, reinterpretation, combinations, and…

As digital integration transforms modern society, equipping young learners with computational thinking (CT) skills has become an essential educational goal. However, many education systems face challenges in adapting curricula to include CT, particularly in early childhood education where resources, teacher preparedness, and instructional design…

Having students solve shape puzzles, such as with pattern blocks or tangrams, is a popular way to encourage students to compose shapes in different ways and talk about the effects of different compositions (Clements et al., 2004; Clements & Sarama, 2009; Sales, 1994), meeting Common Core geometry standards in kindergarten through second grade…

It is important to work on verbal mathematical problem-solving skills, which is one of the high-level skills with which students have difficulty. Supporting problems with visuals has been suggested by mathematics educators to develop this skill. This study examined the effect of the visualization of mathematical problems on the problem-solving…

Computation competence (CC) in simple addition and subtraction using non-counting (NC) strategies is an important learning objective in Grade 1 mathematics but many children, especially low achievers in mathematics, struggle to acquire these skills. To provide these students with the support they need, it is important to have valid and reliable…

The transition from kindergarten to the first grade of elementary school is a crucial developmental period that can significantly influence pupils' academic trajectories. This study aimed to examine whether adaptation to the school environment moderates the relationship between skill-specific performance and academic achievement in two core…

Mathematical reasoning, which plays a critical role in students' capacity to make sense of mathematics, is now emphasised more strongly in various curricula internationally. However, reasoning is sometimes difficult for teachers to recognise, let alone teach. This case study considers video of one teacher's implementation of a problem-solving…

Early detection of and relevant information on children's mathematical difficulties is important to initiate targeted teaching and intervention. This study investigated the extent to which strategy use in single-digit addition provides additional predictive information about 61 grade one children's (6-year-old) mathematical achievement 3 years…

This article explores the usefulness of detective role-play as a research method to facilitate young children's critical thinking. The study examines four specifically designed detective play experiences, adopting an ethical rights-based approach to research with children. This qualitative multiple-case study is grounded in play-based pedagogy…

As early as first grade, some children are more likely than others to perform arithmetic using inefficient or other overt counting strategies. To partially address this problem, the primary investigator developed a skill hierarchy with procedures based on applied behavior analysis. The novel early-intervention program included a combination of…

The hundreds chart is a valuable tool for teachers in elementary mathematics classrooms. The present study investigated the effects of spatial configurations of virtual hundreds charts on children's knowledge of base-ten concepts. Kindergarten and first-grade students were assigned to three instructional conditions in which they worked with a…

Current reading research largely focuses on word reading. This study complements that focus by considering what children do when encountering unknown words and how that problem-solving changes over time. We used overlapping wave theory to describe how children who were having difficulty with reading changed their word-solving actions across nine…

In 2 experiments, I studied the effects of an Equivalence Based Instruction (EBI) math intervention on the emergence of untaught selection responses and abstraction to production responses. In Experiment I, using a multiple baseline design, I implemented the EBI intervention among a group of 17 first grade participants with varying levels of math…

This article focuses on students' meaning-making when working with mathematics textbooks from a multimodal approach that encompasses all resources for communication, which is an under researched area. Central to this study are the designed meanings of the textbooks and the affordances discovered by students when working with the textbooks. Video…
