Abstract

The invention provides a combination teaching aid for high school mathematics; it includes a whiteboard, a box body and a fixed plate; a fixing bolt is fixed on the left side of the whiteboard through threads; a sliding plate is arranged directly below the fixing bolt; a sliding plate is arranged at the lower end of the sliding plate Electric telescopic rod; the upper end of the box is hinged with a revolving door; a fixed plate is arranged directly below the revolving door; vertical plates are arranged on both sides of the fixed plate; the lower end of the vertical plate is installed on the upper surface of the connecting plate; The lower end of the connecting plate is installed on the rotating shaft; the rotating shaft is connected with a motor through a coupling; the outer side of the motor is provided with a soundproof cover; the lower end of the soundproof cover is fixed on the upper surface of the support plate by screws; the lower end of the support plate is installed on On the hydraulic rod; the lower end of the box is provided with a support column; the lower end of the support column is installed with a U-shaped fixing frame through a bearing; the present invention is simple in structure and easy to use, and the whiteboard is provided with fixing bolts, which can be used to fix items used during learning. Prevent items from being cluttered and not found.

Description

technical field [0001] The invention relates to a teaching aid device, in particular to a combination teaching aid for high school mathematics. Background technique [0002] Mathematics is a subject of abstract thinking. When teachers explain mathematical theorems, formulas, geometric figures and mathematical theories, they usually use blackboard writing to explain. When explaining more abstract formulas, theorems and figures, students only use blackboard writing. It is difficult to understand formulas or theorems, especially when explaining permutations and combinations of formulas, theorems or examples, it is difficult for students to digest and understand. [0003] Most of the traditional mathematics teaching aids are formulated around a formula or theorem, which is relatively simple and cannot meet the needs of various teaching. Contents of the invention [0004] The purpose of the present invention is to provide a high school mathematics combination teaching aid to s...
