Financial literacy is ideally suited to be integrated into mathematics courses and taught in an interdisciplinary manner. Students learn best and are motivated when tackling real-world meaningful questions. This article shares how elementary mathematics was applied to better understand the debate about raising the minimum wage and the United…

Generalizing, conjecturing, representing, justifying, and refuting are integral parts of algebraic thinking and mathematical thinking in general (Lannin et al., 2011). The activity described in this article makes a case for generalizing as an overall mindset for any introductory algebra or geometry class by illustrating how generalization problems…

In this study, a STEM activity was designed and implemented for eighth-grade students. The activity was used with thirty students and involved the construction of various hologram pyramids. During the activity, the mathematical concepts used in designing the hologram pyramids were discussed and the resulting hologram images were compared…

What is a teacher to do when students share an idea with underlying mathematics that is different from that of the student contribution being discussed? Could such situations be avoided to begin with? In this article, the authors share strategies that can help teachers better keep the mathematics related to the student contribution under…

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.…

This study examined the quality and types of mathematical tasks used for classroom instruction in an upper secondary school -- gymnasium. All the mathematical tasks presented in nine different school classrooms during the first semester of the school year 2018/2019 were analysed against a 5D analytical framework. The dimensions of the individual…

In this article, the authors share how gameplay with dominoes can leverage students' quantitative reasoning to promote number development and additive reasoning. This article explores three domino games (Basic Dominoes, Just Before/Just After, and Ten Train), and considers the following: (1) rules and details; (2) students' subitizing and unit…

How students build mathematics knowledge together in classrooms is of central concern in research focused on the role of language in learning and doing mathematics. This paper explores how students compose mathematics knowledge together in relation to the social construction of influence. Drawing on the influence framework (Engle et al. in J Learn…

This article explains how explorations into the quadratic formula can offer students opportunities to learn about the structure of algebraic expressions. In this article, the author leverages the graphical interpretation of the quadratic formula and describes an activity in which students derive the quadratic formula by quantifying the symmetry of…

The methods and techniques used by teachers have an important place on the basis of many students' negative perspectives and failures towards mathematics. Integrating technology into mathematics learning environments is inevitable since it is of great importance to create rich learning environments to increase students' interest and understanding…

In this article we address the 'educationalization' of authentic marine navigation tasks for upper secondary mathematics classrooms and their potential for students' learning. Our approach is based on boundary crossing and as well as on the distinction between realistic tasks (targeting students' familiarization with the marine navigation…

Learning mathematics requires real situations that are often faced by students. using the context that is around students for learning mathematics can make the context of mathematics easy to reach by students. This study meant to determine the effectiveness of mathematics learning based on Javanese vegetable salad context in increasing students'…

This dissertation explores the mathematics identities of early elementary school students. Throughout school, many students come to believe that mathematics is not for them or is not a part of who they are or want to be. Previous research has revealed mechanisms that lead to negative relationships with mathematics for middle grade students and…

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…

We present an investigative activity that was set as part of a course of pre-service teachers of mathematics. The emphasis in the course was set on the importance of using the computerized technological tool for teaching the subject. The activity focused on investigating interesting geometrical conservation properties which are not known to the…
