Spatial ability is an important one of the abilities for completing many tasks in everyday life successfully. Spatial ability is considered a type of different ability to others. Therefore, there needs a study on how are the characteristics of spatial abilities and to develop in schools. This paper is to reveal the ways are developing spatial abilities in learning mathematics. Based on literature review from some research, at least that there are six ways to develop spatial abilities in learning mathematics, namely: (1) using spatial language in daily interactions; (2) teaching for sketching and drawing; (3) using a suitable game; (4) using a tangram; (5) using video games; and (6) origami and folding paper. Playing video games like Tetris are exercises for spatial relations, mental rotation, spatial orientation, and spatial visualization.

Abstract Origami is the art of creating a three-dimensional (3D) shape by folding paper. It has drawn much attention from researchers, and the designs that origami has inspired are used in various engineering applications. Most of these designs are based on familiar origami patterns and their known deformations, but origami patterns were originally intended for materials of near-zero thickness, primarily paper. To use the designs in engineering applications, it is necessary to simulate origami in a way that enables designers to explore and understand the designs while taking the thickness of the material to be folded into account. Because origami is primarily a problem in geometric design, this paper develops a geometric simulation for thick origami. The actuation, constraints, and assignment of mountain and valley folds in origami are also incorporated into the geometric formulation. The experimental results show that the proposed method is efficient and accurate. The method can successfully simulate a flat-foldable degree-four vertex, two different action origami, the bistable property of a waterbomb base, and the elasticity of non-rigid origami panels.

<p>When origami is mentioned, the first associations are paper cranes.  But origami is much more, and it is actually a mathematical discipline, so powerful that even NASA uses origami in its space research. Flat origami, where figures are as such as the above mentioned crane, is full of mathematical problems. There are seven origami axioms, widely known as Huzita-Hatori axioms, that describe creases. They represent the mathematically formal description of origami constructions. But when talking about involving origami and space science, we need to mention Miura folding  This form of origami folding is proposed by Japanese astrophysicist Koryo Miura. Miura-ori is a way of folding paper or another flat surface into smaller area.  In the presentation we describe how we have made Miura-ori folding, how we 3D printed and made a model of a space craft in our classroom. Connecting different disciplines and inquiry students learned about the most recent scientific research and applied their knowledge during the project. </p>

This manuscript describes three activities connecting the Tower of Hanoi puzzle to three familiar fractal forms. The first connects coin flipping, paper folding, and the Tower of Hanoi to the Dragon Curve. The second illustrates mathematician Ian Stewart's method for showing how the relationships between possible states of the Tower of Hanoi are related to stages in Sierpinski's Gasket. The final activity compares right-left moves of Tower of Hanoi disks to iterations of the Von Koch Curve.

In this research, we study a method to produce families of origami tessellations from given polyhedral surfaces. The resulting tessellated surfaces generalize the patterns proposed by Ron Resch and allow the construction of an origami tessellation that approximates a given surface. We will achieve these patterns by first constructing an initial configuration of the tessellated surfaces by separating each facets and inserting folded parts between them based on the local configuration. The initial configuration is then modified by solving the vertex coordinates to satisfy geometric constraints of developability, folding angle limitation, and local nonintersection. We propose a novel robust method for avoiding intersections between facets sharing vertices. Such generated polyhedral surfaces are not only applied to folding paper but also sheets of metal that does not allow 180 deg folding.

Origami-inspired active graphene-based paper with programmed gradients in vertical and lateral directions is developed to address many of the limitations of polymer active materials including slow response and violent operation methods. Specifically, we used function-designed graphene oxide as nanoscale building blocks to fabricate an all-graphene self-folding paper that has a single-component gradient structure. A functional device composed of this graphene paper can (i) adopt predesigned shapes, (ii) walk, and (iii) turn a corner. These processes can be remote-controlled by gentle light or heating. We believe that this self-folding material holds potential for a wide range of applications such as sensing, artificial muscles, and robotics.
