Jitterbug ★★★✩✩ Use 12 Squares Finished Model Ratio 1.0 Jitterbug ★★★✩✩ Use 12 squares Finished model ratio 1.0 uckminister Fuller gave the name Jitterbug to this transformation. I first came across B the Jitterbug in Amy C. Edmondson’s A Fuller Explanation (1987).As I didn’t have dowels and four-way rubber connectors, I made several cuboctahedra that worked as Jitterbugs but were not very reversible. Some were from paper and others from drinking straws and elastic thread. My first unit,Triangle Unit, was partly successful as a Jitterbug.A better result came from using three units per triangular face (or one unit per vertex) which was published in 2000. This improved version is slightly harder to assemble but has a stronger lock.The sequence is pleasingly rhythmical and all steps have location points.The pleats in step 18 form the spring that make the model return to its cuboctahedral shape.

  • The Geometry Junkyard: Origami
    Table of Contents Table of Contents 1 Origami 2 Origami The Japanese art of paper folding is obviously geometrical in nature. Some origami masters have looked at constructing geometric figures such as regular polyhedra from paper. In the other direction, some people have begun using computers to help fold more traditional origami designs. This idea works best for tree-like structures, which can be formed by laying out the tree onto a paper square so that the vertices are well separated from each other, allowing room to fold up the remaining paper away from the tree. Bern and Hayes (SODA 1996) asked, given a pattern of creases on a square piece of paper, whether one can find a way of folding the paper along those creases to form a flat origami shape; they showed this to be NP-complete. Related theoretical questions include how many different ways a given pattern of creases can be folded, whether folding a flat polygon from a square always decreases the perimeter, and whether it is always possible to fold a square piece of paper so that it forms (a small copy of) a given flat polygon.

  • Use of Origami in Mathematics Teaching: an Exemplary Activity
    Asian Journal of Education and Training Vol. 6, No. 2, 284-296, 2020 ISSN(E) 2519-5387 DOI: 10.20448/journal.522.2020.62.284.296 © 2020 by the authors; licensee Asian Online Journal Publishing Group Use of Origami in Mathematics Teaching: An Exemplary Activity Davut Köğce Niğde Ömer Halisdemir University, Faculty of Education, Department of Elementary Mathematics Education Turkey. Abstract Students’ attitudes and motivations toward mathematics decrease as they intensively confront cognitive information along the process of mathematics teaching in general. One of the most important reasons for this is the lack of activities for affective and psychomotor domains in the mathematics teaching process. One way to overcome this problem is to include activities through which students can participate effectively in the teaching process. For example, activities performed using origami can be one of them in teaching the attainments covered by the field of geometry learning in mathematics curriculum. Therefore, this study was carried out to present an exemplary activity about how origami can be used when teaching mathematics in secondary schools and to identify preservice teacher opinions on this activity. The activity presented in this study was performed with 32 preservice elementary mathematics teachers attending the faculty of education at a university and taking the Mathematics Teaching with Origami course, and their opinions were taken afterwards. At the end of the application, the preservice teachers stated that such activities would have very positive contributions to students’ mathematics learning. In addition, the preservice teachers communicated and exchanged ideas with each other during the application. It is therefore recommended to use such activities in mathematics teaching.

  • Paper Pentasia: an Aperiodic Surface in Modular Origami
    Paper Pentasia: An Aperiodic Surface in Modular Origami a b Robert J. Lang ∗ and Barry Hayes † aLangorigami.com, Alamo, California, USA, bStanford University, Stanford, CA 2013-05-26 Origami, the Japanese art of paper-folding, has numerous connections to mathematics, but some of the most direct appear in the genre of modular origami. In modular origami, one folds many sheets into identical units (or a few types of unit), and then fits the units together into larger constructions, most often, some polyhedral form. Modular origami is a diverse and dynamic field, with many practitioners (see, e.g., [12, 3]). While most modular origami is created primarily for its artistic or decorative value, it can be used effectively in mathematics education to provide physical models of geometric forms ranging from the Platonic solids to 900-unit pentagon-hexagon-heptagon torii [5]. As mathematicians have expanded their catalog of interesting solids and surfaces, origami designers have followed not far behind, rendering mathematical forms via folding, a notable recent example being a level-3 Menger Sponge folded from 66,048 business cards by Jeannine Mosely and co-workers [10]. In some cases, the origami explorations themselves can lead to new mathematical structures and/or insights. Mosely’s developments of business-card modulars led to the discovery of a new fractal polyhedron with a novel connection to the famous Snowflake curve [11]. One of the most popular geometric mathematical objects has been the sets of aperiodic tilings developed by Roger Penrose [14, 15], which acquired new significance with the dis- covery of quasi-crystals, their three-dimensional analogs in the physical world, in 1982 by Daniel Schechtman, who was awarded the 2011 Nobel Prize in Chemistry for his discovery.

  • Martin Gardner Modular Origami G4G12 Rhombic Dodecahedron by Peter Knoppers
    Martin Gardner Modular Origami G4G12 Rhombic Dodecahedron By Peter Knoppers Artwork © by Scott Kim; originally designed for G4G6; reused with permission. Description This artwork was designed for G4G6 to cover the 6 faces of a cube. As most of you will know, a Rhombic Dodecahedron can be constructed from a cube by adding a pyramid with square base and height 0.5 to each face of the cube. Faces of a pyramid on adjacent cube faces are then joined to create 12 Rhombuses. To match the artwork, it needed to be stretched by a factor √2 along the long diagonal of the Rhombus. The (very charming) property of this artwork on a cube that all faces show essentially the same image is not maintained. The Rhombic Dodecahedron requires three different clippings. Folding instructions There are 12 numbered pages. Each page must be folded the same way. Solid lines (as printed on the sheets) become (initially) hill folds; dotted lines valley folds. The printed lines are indications; you get a better result by making fold markings (step 1 below) and folding the various corners of the paper up to those markings in steps 2..7 as indicated below. The image shown here is © by Ole Arntzen who has a web site that generates pages for a 12 month calendar using this folding and assembly method (image reused with permission). You can find this calendar generator at http://folk.uib.no/nmioa/kalender/ . 1 Put the printed side up. Mark the center of the long edges by folding the A4 page in half; Only make the fold near the edges to mark the halfway points; unfold.

Mechanical properties of paper, as a material, are simple. A sheet of paper is rigid in tangential direc- tions. Indeed, it cannot be stretched, compressed, or sheared. If a sheet of paper is constrained on a plane, it would only be possible to achieve rigid motions, i.e., rotations and translations of the whole sheet. On the other hand, in the normal direction it can be easily folded. This is due to the infinitesimal thickness of the paper and to Figure 2.
