Mathematics probability teaching demonstration device

Abstract

The invention discloses a mathematics probability teaching demonstration device, comprising a bottom plate; support legs are integratedly formed on the lower end of the bottom plate; the lower end of the bottom plate is provided with an iron plate through adhesion; the lower end of the iron plate is provided with a magnet; the upper end of the bottom plate is provided with a connection handle through welding; the connection handle is provided with a positioning plate through a bearing; the outer rim of the positioning plate is provided with positioning holes; the connection handle is provided with a positioning bolt matching with the positioning holes; and a main shaft is integratedly formed on the upper end of the positioning plate. The mathematics probability teaching demonstration device realizes the direct demonstration function during the probability teaching through designing a random rotation plate of an inner-outer plate. Besides, the mathematics probability teaching demonstration device also has the function of regulating the inclination angle of the plate, and regulates the inclination angle of the demonstration plate in real time according to the requirement. The invention is simple in structure, gives a strong visual impression, and maximally satisfies various demonstration requirements on the class.

Description

technical field [0001] The invention relates to the field of teaching demonstration tools, in particular to a mathematical probability teaching demonstration device. Background technique [0002] Probability and statistics are one of the basic contents of mathematics teaching and an important part of modern mathematics. However, students often cannot understand probability and statistics because they are too abstract, especially when teaching teachers are explaining probability events. Sometimes, the teacher can only explain to the students by writing on the blackboard that the students do not understand thoroughly. In the teaching process, there is a lack of auxiliary teaching tools for probability and mathematical statistics, so the learning efficiency of the students is low.

[0002] Probability and statistics are one of the basic contents of mathematics teaching and an important part of modern mathematics. However, students often cannot understand probability and statistics because they are too abstract, especially when teaching teachers are explaining probability events. Sometimes, the teacher can only explain to the students by writing on the blackboard that the students do not understand thoroughly. In the teaching process, there is a lack of auxiliary teaching tools for probability and mathematical statistics, so the learning efficiency of the students is low. If we can invent an effective A new type of probability teaching demonstration device that improves students' learning efficiency and can more intuitively demonstrate probability-related laws can solve such problems. For this reason, we provide a mathematical probability teaching demonstration device
