Stereoscopic multi-element teaching aid

Abstract

The invention belongs to the technical field of mathematics teaching tools, and in particular relates to a three-dimensional multiple teaching aid, which includes three groups of corner bodies combined into a triangle, and each group of corner bodies includes a mother rod, a child rod, and a first T-shaped rod 1. A second T-shaped rod and a nut. There is a groove running through the female rod at the upper center of the left end surface of the female rod. The groove matches the sub-rod. A first lug is respectively provided on the front and rear sides of the right end face, and a second lug is respectively provided on the front and rear sides of the lower part of the right end face of the sub-rod. A third hinge rod is provided between the two second lugs, and the first T The shaped rod includes a first hinged cylinder and a threaded rod, the first hinged cylinder is sleeved on the first hinged rod, the nut is sleeved on the threaded rod, the second T-shaped rod includes a second hinged cylinder and a sleeve, and the second hinged cylinder Sleeved on the third hinged rod. Its purpose is to help students intuitively understand the theory that the sum of the three interior angles of a triangle is equal to 180°.

Description

technical field [0001] The invention belongs to the technical field of mathematics teaching tools, and in particular relates to a three-dimensional multiple teaching tool. Background technique [0002] In the field of mathematics, the sum of the three interior angles of any triangle is equal to 180°. This is common knowledge in the field of mathematics. However, for students, when they first come into contact with this theory, they do not necessarily know this theory. Basically, there is a teacher's education. Coupled with the verification of various methods, such as the method of measurement to get this theory, but students do not have an intuitive understanding of this theory. In this field, there is also a lack of professional demonstration tools to demonstrate this theory, which prevents students from intuitively understanding this theory.
