Multifunctional advanced mathematics learning teaching aid

Abstract

The invention provides a multifunctional advanced mathematics learning teaching aid and belongs to the technical field of teaching aids. The problem that an existing teaching aid is inaccurate in positioning and single in function is solved. The multifunctional advanced mathematics learning teaching aid comprises a chassis, wherein a cavity is arranged on the chassis, one end of the cavity penetrates through the side face I of the chassis, and the other end of the cavity is blocked by the side face II of the chassis. The multifunctional advanced mathematics learning teaching aid further comprises a teaching module, wherein the teaching module comprises a rolling column and a display block, wherein a groove is formed in the outer wall of the rolling column, the display block is absorbed onto the groove and can rotate along the axis of the inner wall of the cavity and abut against the inner wall of the cavity, a magnet I is arranged on the inner wall of the cavity, and a magnet II corresponding to the magnet I is arranged on the outer wall of the rolling column. The multifunctional advanced mathematics learning teaching aid further comprises a rotary shaft with one end fixedly connected with a shifting block, wherein the rotary shaft is sleeved with the rolling column. When single probability is required to be demonstrated, the corresponding display block is turned through the rolling column, and observation can be achieved through the opening position of the inner wall of the cavity, on the front surface of the chassis. When the probability distribution is required to be demonstrated, the shifting block is pushed, and the teaching module can be wholly lifted through the rotary 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
