Mathematical probability demonstration device

Abstract

A mathematical probability demonstration device includes a base. A box made of a transparent material is arranged above the top of one side of the base. Buffer rods are fixedly installed on the frontand back sides of the bottom of the box. The lower ends of the buffer rods are fixedly installed on the top of the base. A transverse plate is fixedly installed at the lower ends of the two sides inside the box. Two first through holes are arranged in one side inside the box, and one through hole is flush with the top of the transverse plate. A box with an open top is fixedly installed on one sideof the box. Second through holes are arranged in the two sides inside the box. The inside of one first through hole is communicated with the inside of one second through hole. The mathematical probability demonstration device is reasonable in structure design and convenient to use. In the using process, there is no need to place a dice manually, and the trouble of manual dice pickup is avoided. The operation time is saved, and the efficiency of class is improved. A cushioning and shock absorbing function can be achieved, so that the mathematical probability demonstration device is more stablein the working process.

Description

technical field [0001] The invention belongs to the field of mathematics teaching devices, in particular to a mathematical probability 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, when learning probability and statistics, students cannot understand them well because of their abstract nature. At the time of the incident, the teacher could only explain to the students by writing on the blackboard. The students could not understand it thoroughly. During the teaching process, they lacked some auxiliary teaching tools for probability and mathematical statistics. Therefore, the learning efficiency of students was low. Contents of the invention [0003] The invention provides a mathematical probability demonstration device to solve the defects in the prior art. [0004] The present invention is achieved through the following technical solu...
