A multifunctional advanced mathematics learning teaching aid

Abstract

The invention provides a multifunctional advanced mathematics learning teaching aid, which belongs to the technical field of teaching aids. It solves the problems of inaccurate positioning and single function of existing teaching aids. The multi-functional advanced mathematics learning teaching aid includes a chassis, which is provided with a cavity, one end of the cavity runs through the side one of the chassis, and the other end is blocked by the side two of the chassis, and also includes a teaching module, the teaching module includes rollers and display blocks, rollers There is a slot on the outer wall, the display block is adsorbed to the slot, the display block can rotate along the axis of the inner wall of the cavity and the display block can be against the inner wall of the cavity, a magnet is arranged on the inner wall of the cavity, and the outer wall of the roller is provided with The magnet one corresponding to the magnet two also includes a rotating shaft with a shift block fixedly connected at one end, and the roller is sheathed on the rotating shaft. When it is necessary to demonstrate a single probability, the corresponding display block can be obtained by rotating the roller, and it can be observed through the opening position of the inner wall of the cavity on the front surface of the chassis; when it is necessary to demonstrate the probability distribution, push the dial fast, and the teaching module can be raised as a whole through the rotating shaft .

Description

technical field [0001] The invention belongs to the technical field of teaching aids, and relates to a multifunctional advanced mathematics learning teaching aid. Background technique [0002] Now when teachers are teaching probability, there are no teaching aids available, and they can only use words and language to explain on the blackboard. Probability is an abstract concept, and it is difficult for students to quickly understand it by explaining it in this way. [0003] For example, Chinese patent application [Application No.: 201320257234.5; Publication No. 203217830U] discloses a probability mold teaching aid for university mathematics teaching, which includes a magnetic chassis, a partition, a teaching module, and a suction cup. The board is divided into several spaces of the same shape and size, and teaching modules are arranged in the spaces, and suction cups are provided at the four corners of the back of the magnet-type chassis, which is characterized in that it a...

Problems solved by technology

[0005] However, the above-mentioned two existing teaching aids are single and very functional. When the lecturer needs to display a single probability by flipping the teaching module and stretch the sliding bar to display the probability distribution, he needs to take two teaching aids at the same time, which is very inconvenient and displays a single probability. Because the teaching aids use the rotating shaft to rotate the teaching module, the positioning of the teaching module is not accurate, the classroom time is precious, and the teacher does not need to waste time on it
