Integrated multipurpose teaching aid for mathematics teaching

Abstract

The invention relates to an integrated multipurpose teaching aid for mathematics teaching, and aims to solve the technical problems that in the mathematics teaching process of a current teaching aid, the number of drawing styles is small, complex graphs need to be matched with various teaching aids, and the rotation angle of a graph rotating by a special angle is not in place. The integrated multipurpose teaching aid comprises a projection device and an imaging cylinder, wherein the projection device comprises an outer shell and a projection cavity, the left side outer wall of the projection cavity is connected to the left side wall in the outer shell, the right end opening handle of the projection cavity is in threaded connection with the imaging cylinder, the rear portion of the imaging cylinder is located at the front end in the projection device and extends out, the projection cavity comprises a light source and a shell, and the left side of the light source is connected to the left side wall of the interior of the projection cavity.According to the invention, switching of a plurality of graphs can be realized by replacing an imaging lens, and a teacher can be helped to rapidly draw the graphs by projecting a plurality of graph contours onto a blackboard, so that the drawing of a complex graph only needs to be independently completed by the design.

Description

technical field [0001] The invention relates to the field of mathematics teaching aids, in particular to an integrated multipurpose teaching aid for mathematics teaching. Background technique [0002] In the process of teaching, teachers often need various teaching aids to assist teaching, so as to facilitate teachers' teaching and improve students' awareness of knowledge, especially in the process of mathematics teaching, it is necessary to use various graphics to display Mathematics knowledge, but the teaching aids in the prior art often have a single role in the drawing process, and the graphic styles that can be drawn by using one teaching aid alone are less, and when drawing complex graphics, multiple teaching aids are generally required to be used in conjunction, resulting in graphics in the mathematics teaching process. The drawing time is too long and the teaching progress is slow. Contents of the invention [0003] The purpose of the present invention is to overc...
