Drawing writing teaching device for mathematical classroom

Abstract

The invention discloses a drawing writing teaching device for a mathematical classroom. The device comprises a movable base, universal rolling wheels are arranged at four corners of the bottom of thebase of the movable base, a drawing writing main board is fixedly arranged above the base body of the movable base, a manual push handle is arranged in the middle position of a front panel of a strip-shaped powder scraping block, a plurality of first dust suction nozzles are uniformly communicated on the upper plate surface of a first scraping brush, the lower plate surface of a second scraping brush are uniformly communicate with a plurality of second dust suction nozzles, a guide sliding block matched with a groove cavity of a guide rail groove, a lifting positioning sleeve matched with arod body of vertical part of a movable supporting rod, a book placing seat is integrally and fixedly arranged on the front end surface of a sleeve body of the lifting positioning sleeve, and a tool storage box is further fixedly arranged at the right side of the top end of the front panel of the drawing writing main board. According to the drawing writing teaching device for a mathematical classroom, the actual drawing operation of a mathematical teacher is facilitated, the practicability is high, and the use requirements of the mathematical teaching are met.

Description

technical field [0001] The invention relates to the related technical field of teaching equipment, in particular to a drawing and writing teaching device used in mathematics classrooms. Background technique [0002] Mathematics is a subject that studies concepts such as quantity, structure, change, space, and information, and it is a kind of formal science from a certain perspective. Mathematicians and philosophers have a range of views on the exact scope and definition of mathematics. In the development of human history and social life, mathematics also plays an irreplaceable role, and it is also an indispensable basic tool for learning and researching modern science and technology. Plane geometry studies the geometrical structure and metric properties (area, length, angle, positional relationship) of straight lines and quadratic curves (ie, conic sections, that is, ellipses, hyperbolas, and parabolas) on a plane. [0003] At present, teachers often use teaching aids to d...

Problems solved by technology

[0003] At present, teachers often use teaching aids to draw on the blackboard in the process of mathematics teaching. Especially in the process of geometric drawing demonstration, they need to use drawing boards. Air pollution caused by a large amount of dust floating after writing will affect the health of teachers and students and pollute the classroom environment. In addition, mathematics teachers often need to hold books in one hand and use the other hand to draw pictures for reference. Drawing and writing makes it inconvenient for the teacher to operate and affects the drawing effect. The teacher often needs to carry drawing tools, which is very troublesome and poor in practicability, and needs to be improved
