Abstract

The present invention is a teaching aid developed for use in class of mathematics education, and connects both ends of one type of Geo Stick [Fig. 1] to make various plan types (Fig. 2), It is a design of mathematics teaching tools designed to make various three-dimensional figures [Fig. 4] by connecting to each other as shown in [Fig. 3]. It is characterized by being able to make all polyhedrons.

Description

    Geometry Bar {Geo Stick}

      This design is a parish developed for the semester to replace the role of the import parish called Geo Fix [Fig. 5], which was developed to be used for the study of mathematical figure domain. The Geo Stick not only enables all class activities that can be realized by imported products, but also helps to learn and understand the basic principles of shapes and geometrics by making the plan itself, as well as investing in the production of products. It is expected that the price competitiveness of the product will be high in the market for the reason

     The present invention is a mathematical experience teaching to make various three-dimensional figures [Fig. 4] by connecting several to several dozen Geo Sticks [Fig. 1], which are the core of the idea. When this is completed, it can be shaken or crushed. On the contrary, if it is manufactured too tightly, a problem arises in that force is applied to the hands during the creation and disassembly of each plane and three-dimensional figures. The technical challenge is to adjust the tolerances appropriately at each connection point so that the possible solid working activities can be done and the finished solid figure can remain solid.

   The figure bar is composed of two parts. One is the bar part, and the pins (males) and holes (arms) that make up the same principle as the snap button are arranged so that they are symmetrical to each other. It is functionally designed to form a triangle by connecting the pins of the A bar and the hole of the B bar, the pins of the B bar and the hole of the C bar, and again the pins of the C bar and the hole of the A bar. It is a wing part that can be bent at a free angle with the figure bar, and pins and holes with a function that can be attached to and detached from the other part of the figure bar are arranged to be symmetrical. It is functionally structured to make shapes.

     The present invention can help to adequately explain the specific teaching contents of classes required by mathematics teachers in each school at the time that the status of the class structures required in the school class is being expanded by the 7th education amendment. As a parish, it is expected to not only have more versatile use to make all 13 quasi-polyhedrons that were previously limited in import parishes, but also to be highly competitive in price.

Claims (1)

     The present invention is designed to create various three-dimensional structures by using one type of figure bar. Pins and holes, which function like a snap button, are arranged symmetrically at both ends of the figure bar, so that several figure bars are placed on each other. Various basic shapes can be connected to each other, and the wing part attached to the bar to be bent at a free angle has a symmetrical pin and hole that can be detached from each other. Figure bar.
