Problems solved by technology

The disadvantages are that the variety is incomplete and the quantity is small. It can only be demonstrated by the teacher and the students can just watch it; especially the structure is fixed, the volume is too large, and the storage is cumbersome.

Embodiment approach

[0043] Since the components in the component set can be assembled into various spatial geometric models, and the assembly methods are similar, we only take the steps of the assembly method of a cube model as an example, as a demonstration of the assembly of all other three-dimensional geometric models, so as to avoid repetition .

[0044] As shown in Figure 5, insert the small tenon OO' in the center of two square plane frames ABCD into the small holes J at both ends of the central column HI; respectively insert the small tenon at both ends of the four ribs FG into the plane frame ABCD The vertices A, B, C, and D are placed in the small holes E of the arc-shaped bayonet sockets on the sides; so far, the cube model shape ABCD-A'B'C'D' is successfully assembled.

[0045]If another piece of square planar frame ABCD arc-shaped bayonet E is respectively clamped on the ridge rods of the above-mentioned assembled square phantom ABCD-A'B'C'D' and slides up and down parallelly along th...

Abstract

The invention is a space geometric body model component set, composed of various regular polygons, circles and semicircular planar frames, punched of organic raw material and having heights or diagonals and round rod components and central poles vertical to them as well as semicircular ring with seat and components able to assemble a space reference system, according to assembling requirement, selecting corresponding components from the component set to be able to assemble models such as pole, cone, truncated cone, and sphere, models simulating points, lines and surfaces in the space and models of space right-angle reference system and space vector; and the component set is multi-purpose, simple in structure and simple to manufacture, and especially suitable for high-school teachers or students to teach or study 3D geometric knowledge.

Description

technical field [0001] The invention relates to a teaching and learning tool, aiming to provide a "spatial geometry model component set". Background technique [0002] "Geometry is difficult, algebra is complicated." Solid geometry is a key content of mathematics teaching in senior high school, and it is also a prominent difficulty. The difficulty lies in the fact that young students have little experience and lack spatial imagination, which makes teachers worry about teaching and speaking. The Ministry of Education’s new “General High School Mathematics Curriculum Standards” specifically states on page 22, “The primary teaching focus of solid geometry is to help students develop spatial imagination. Teachers should provide rich physical models or geometric figures presented by computer software to help students Recognize the structural characteristics of spatial geometry..." [0003] For a long time, in the teaching of solid geometry in senior high schools in my country, ...
