Do this for vertical and horizontal so you can identify the center.Fold the top right and bottom left corners to the center.Repeat, fold the top left and bottom right corners to the center.Fold model in half. ---> go back to Modular Origami Page---> see more Free Origami Diagrams
Origami Flash Cards Origami Flash Cards Here's an idea that goes along with the Multiplication Practice Sheets I created to help my students become more proficient at learning multiplication facts. Start with a 4.25" square of xerox paper. (You can get four squares from one sheet of paper.) Fold it in half three times as shown below. After making the three folds, unfold the whole thing and refold it so that the diagonal folds are ridges and the 90 degree folds are valleys. Collapse the valleys inward as you bring the ridges on both sides together. Lay the paper on its side and flatten it. The last step is easy. The example below shows how to do this for the 4's family. When you've done all four outside triangles, refold the paper, and do the inside four triangles with the remaining facts. How to Use The Multiplication Practice Sheets provide practice at learning either the products or the factor needed to make a particular product. Multiplication Practice Sheets Questions?
La chronique de Mélisande* Au cours des années, j'ai créé plusieurs dizaines de modèles. Pour certains d'entre eux, j'ai publié des instructions, accessibles via la rubrique diagrammes de ce blog. D'autres ne subsistent que par une photo sur flickr et quelques croquis dans mes archives manuscrites. Longtemps, j'ai attendu le prince charmant, un as du dessin vectoriel qui serait prêt à diagrammer toutes mes créations ; je ne vois toujours rien venir, et à mon âge, cela devient improbable. Mieux vaut profiter des quelques années qui me restent avant l'Alzheimer pour faire ce travail moi-même. Deux de mes modèles figurent dans le dernier livre de Meenakshi Mukerjee. Le premier résultat de mes efforts est présenté dans le billet précédent. Je partage toujours mes idées de création par des photos, CP, tutoriaux, sur flickr ou ailleurs, et cela ne va pas changer. J'envisage de publier mes futurs diagrammes dans des livrets de convention ou autres ouvrages collectifs.
Modular origami Modular origami or unit origami is a paperfolding technique which uses two or more sheets of paper to create a larger and more complex structure than would not be possible using single-piece origami techniques. Each individual sheet of paper is folded into a module, or unit, and then modules are assembled into an integrated flat shape or three-dimensional structure by inserting flaps into pockets created by the folding process. These insertions create tension or friction that holds the model together. Definition and restrictions Examples of modular origami made up of Sonobe units Modular origami can be classified as a sub-set of multi-piece origami, since the rule of restriction to one sheet of paper is abandoned. The additional restrictions that distinguish modular origami from other forms of multi-piece origami are using many identical copies of any folded unit, and linking them together in a symmetrical or repeating fashion to complete the model.

Origami-Make: Instructions to learn how to make origami models Mukerji Excerpt Primary Magazine - Issue 58: Focus on In this three-part series, Barbara Carr, an independent consultant who is also an accredited PD lead for the NCETM, outlines how to use Dienes (Base 10) equipment and the Roman Numeral system to help children develop better conceptual understanding of how place value in our number system works. Do we really make the most of our wonderful number system? There has been surprise, possibly annoyance, even outrage at the introduction of Roman Numerals in the 2014 mathematics curriculum. Year 4 draft programme of study: Read Roman numerals to 100 (I to C) and know that over time, the numeral system changed to include the concept of zero and place value. The guidance states: Roman numerals should be put in their historical context so pupils understand that there have been different ways to write whole numbers and that the important concepts of zero and place value were introduced over a period of time. Year 5 draft programme of study: Pupils identify the place value in large whole numbers. Rules:

Origami Folding Instructions - Instructions on How to Make Origami Folding Modular Models - Polyhedrals by Francis Ow Folding Modular Models - Polyhedrals This page has many graphics and illustrate how to fold a few simple models. Due to its graphical nature, loading of this page will be slow. Modular models are where simple modules are first folded, these simple modules are then lock together without the use of glue to form the complete model. Polyhedral Models Folding are a subset of Modular Models Folding. Diagrams avaliable here include: 120 degrees module - to construct truncated tetrahedron, cuboctahedron, dodecahedron, rhombicuboctahedron, etc. How to fold a 120-degree module Using this module and folding the required number modules you can construct a Truncated Tetrahedron, Cuboctahedron, Dodecahedron, Rhombicuboctahedron, etc. How to fold a 135-degree module Using modules that can interlock at various angles, I have been able to devise many kinds of other geometrical models. I wish you luck and many hours of happy frustrating fun!
