Abstract

The invention discloses a spatial graph presentation combined teaching aid for primary school mathematics. The spatial graph presentation combined teaching aid is formed by connecting two cubes with the same size, wherein a conical blind hole is formed in the center of the external surface of one cube, a cone is arranged in the conical blind hole and sucked by using a conical fixed magnet set, a first hemispherical groove which accommodates a first hemisphere is formed on the internal surface of the cube, and the first hemisphere is sucked with the first hemispherical groove by using a first hemispherical fixed magnet set; a horizontal cylindrical blind hole is formed in the center of the external surface of the other cube, a cylinder is arranged in the cylindrical blind hole and sucked by using a cylindrical fixed magnet set, a second hemispherical groove which accommodates a second hemisphere is formed on the internal surface of the cube, and the second hemisphere is sucked with the second hemispherical groove by using a second hemispherical fixed magnet set; and a hemisphere joint magnet set is arranged on a joint surface of the first hemisphere and the second hemisphere. The spatial graphical presentation combined teaching aid has few parts, is convenient to assemble and carry, and can intuitively present the shapes of a cuboid, the cubes, the cylinder, the cone and spheres.

Description

technical field [0001] The invention relates to a teaching aid, in particular to a combination teaching aid for primary school mathematics space graphics demonstration. Background technique [0002] Teaching aids play an important role in teaching, especially in the lower grades. Scientific and effective use of learning aids can not only mobilize students' enthusiasm for learning, stimulate students' intuitive and visual thinking, but also make abstract mathematical knowledge intuitive and vivid. , which is conducive to students' better understanding and mastery. The existing teaching aids for elementary school mathematics space graphic demonstration have too many components, are too scattered, are not easy to carry, and are difficult to assemble and complicate for elementary school students to participate in, thus affecting the teaching and learning effects. Contents of the invention [0003] In order to overcome the defects in the above-mentioned existing teaching aids,...
