A teaching aid for basic mathematics

Abstract

The invention provides a teaching aid for basic mathematics and belongs to the technical field of teaching tools. The teaching aid for basic mathematics comprises a fixed base, a first drawing tool and a second drawing tool; the fixed base comprises a first fixed plate and a second fixed plate, and a connection column is arranged between the first fixed plate and the second fixed plate; one end ofthe connection column is fixedly connected with the first fixed plate, and the other end of the connection column is fixedly connected with the second fixed plate; a first positioning column is arranged on the outer side of the second fixed plate; the tail end of the first positioning column is provided with a pointed part in the shape of an inverted cone; a first index plate is arranged on the outer side of the second fixed plate; the first drawing tool comprises a first drawing ruler, a second drawing ruler and a second index plate; the second drawing tool comprises a first supporting leg and a second supporting leg; and the first supporting leg and the second supporting leg are both arranged on the other side of the fixed base. The teaching aid is compact in structure and easy to operate, the whole teaching aid integrates a set square, a straight ruler, a protractor, compasses and other drawing tools, is convenient to use and carry and improves the teaching quality.

Description

technical field [0001] The invention belongs to the technical field of teaching tools, and in particular relates to a teaching tool for basic mathematics. Background technique [0002] Basic mathematics is one of the secondary subjects under mathematics. Basic mathematics, also known as pure mathematics, is the core and basic part of mathematical science. Geometry is an indispensable subject in basic mathematics. [0003] In the teaching of geometry, geometric drawing is a very important skill requirement in mathematics teaching. It is widely used in mathematics teaching and related mathematics research. Using appropriate drawing tools for geometric drawing can better help Students understand geometric principles, geometric methods, and geometric content. Geometric drawing requires various teaching aids, such as set squares, rulers, protractors, compasses, etc. [0004] In the existing geometry teaching, the mathematics teacher often needs to carry a variety of teaching ai...

Problems solved by technology

[0004] In the existing geometry teaching, the mathematics teacher often needs to carry a variety of teaching aids such as compasses, rulers, and triangular boards, and the compasses are often caused by collisions and damage to the drawing pen during the carrying process. At the same time, the existing compasses have only one fixed point. , it is easy to move when drawing, so that drawing circles and arcs is often inaccurate, which affects the teaching effect, and these teaching aids are relatively scattered, and need to be replaced back and forth when drawing, wasting precious teaching time, greatly increasing the workload of teachers, and seriously affecting the teaching effect. teaching quality, and carrying too many tools is not only laborious, but also very inconvenient
