Problems solved by technology

[0002] When teaching mathematics to elementary school or school-age children, when teachers instruct addition, subtraction, multiplication, and division operations, they often have to write calculation expressions on the blackboard, which will delay the progress of the class. In order to avoid writing calculation expressions on the blackboard, many teachers make PPT directly Demonstration and explanation, but such a teaching method can not increase children's learning interest and improve the fun of teaching, nor can they quickly grasp the knowledge points, so it is very necessary to invent a teaching demonstrator specially used for teaching mathematics multiplication

Abstract

The invention relates to a teaching appliance and especially relates to a multiplication teaching demonstrator. The demonstrator comprises an operation base plate, an X support shaft and a Y support shaft. The X support shaft is provided with a transverse digital board. The Y support shaft is provided with a vertical digital board. The operation base plate is provided with counting grids. The counting grids are arranged in an N row and M column matrix mode. A left side of the operation base plate is connected to the Y support shaft. A lower side of the operation base plate is connected to the X support shaft. The X support shaft is provided with M line shaft sleeves. The Y support shaft is provided with N line shaft sleeves. The line shaft sleeves are twined with stay wires. The stay wires are divided into two segments. One segment is intersected and distributed among the counting grids arranged in the N row and M column matrix mode and the other segment is twined on the line shaft sleeves. By using the teaching demonstrator which uses a multiplication array to carry out multiplication exercises, an operating method is interesting and interactive so that operation is simple; children interests are stimulated and a multiplication calculating capability is increased; and a learning interest are increased.

Description

technical field [0001] The invention relates to a teaching tool, in particular to a multiplication teaching demonstrator. Background technique [0002] When teaching mathematics to elementary school or school-age children, when teachers instruct addition, subtraction, multiplication, and division operations, they often have to write calculation expressions on the blackboard, which will delay the progress of the class. In order to avoid writing calculation expressions on the blackboard, many teachers make PPT directly Showing and explaining, but such a teaching method can not increase children's learning interest and improve the fun of teaching, nor can they quickly grasp the knowledge points, so it is very necessary to invent a teaching demonstrator specially used for teaching mathematics multiplication. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention provides a teaching demonstrator that utilizes the multi...
