This report describes an activity that helps organic chemistry students to better understand organic molecules as 3-dimensional objects. To accomplish this goal, the activity employs a unique three-way combination of analyzing computer-generated 3-dimensional renditions of open access X-ray crystallography data, building physical 3-dimensional…

This study compares the effect of Augmented Reality (AR) based virtual manipulatives to physical manipulatives for teaching geometric shapes to preschool children to improve their spatial skills. A quasi-experimental research design was utilized in order to answer the research questions. The context of the research was a public primary school in…

Perceptually rich concrete manipulatives benefit mathematics learning. Because students should be challenged to consider connections between two-dimensional (2D) and three-dimensional (3D) perspectives of conics (NCTM 2000), this article describes hands-on teaching techniques that promote this type of student reasoning. This article aims to (1)…

In this article, we present a systematic review of literature on augmented reality (AR) supported for early language learning. We analyzed a total of 53 papers from 2010 to 2019 using qualitative analysis with complementary descriptive quantitative analysis. Our findings revealed three main AR learning activities: word spelling games, word…

Geometry belongs to branches of mathematics that develop students' visualisation, intuition, critical thinking, problem solving, deductive reasoning, logical argument and proof (Jones, 2002). It provides the basis for the development of spatial sense and plays an important role in acquiring advanced knowledge in science, technology, engineering,…

Many students have difficulties in geometric and spatial thinking (see Pittalis & Christou, 2010). Students who are asked to construct models of geometric thought not previously learnt may be forced into rote learning and only gain temporary or superficial success (Van de Walle & Folk, 2008, p. 431). Therefore it is imperative for…

The purpose of this book is to introduce the geoboard as an effective tool that can help young children understand geometry as they develop spatial sense and mathematical thinking. Activities are clustered into three main sections: beginning geoboard explorations, exploring polygons, and coordinates. Blackline masters are included. (MKR)

Eleven activities with a puzzle consisting of 12 five-square shapes are presented, with some solutions illustrated. (MNS)

Four worksheets are presented, each using cubes to develop students' spatial visualization abilities. Directions and answer keys are both included. (MNS)

Suggests discovery activities in spatial awareness for elementary math, utilizing home-made geometric shapes and soma cubes. (SJL)

Geometry tiles can be used to develop and extend intuitive geometric concepts by helping children visualize geometric shapes and communicate spatial relationships. Eleven activities are described for introduction, basic concepts, geometric figures, transformations, and metric geometry. (MNS)

Spatial concepts are important to the development of many skills, including reasoning and problem solving. Here are guidelines for making geometry learning more effective for elementary-grade students. (Editor)

Describes two activities involving sorting, counting, and determining relationships that use sameness and difference, spatial skills, pattern identification, number bonds, and generalization. (DDR)

Some activities with tangrams and their use for investigating fractions, constructions, and percentages are presented, with worksheets included. (MNS)

The articles in this collection of readings come principally from the last ten years of the "Arithmetic Teacher." The emphasis is on teaching mathematics in grades K-6, although some articles may include teaching ideas and activities for grades seven and eight. Articles on measurement geometry are not included; the focus is on the development of…
