Embodiment 1

[0010] First make a measuring angle circular plate 1 with a scale of 360 degrees, then install a circular axis 2 on the measuring angle circular plate 1, and install two graduated rulers 3 on the circular axis 2, and dig a movable groove in the center of one of the graduated rulers 4. Install the movable clip 5 within the movable groove range, and dig a chalk clip hole 6 above the movable clip to make a multi-purpose mathematics teaching aid.

[0011] When in use, the scale ruler 3 can be directly used as a straightedge and is practical, and the angle formed by the two scale rulers 3 can be used as a triangle ruler, and can also measure the angle of the angle. Install chalk on the chalk clip hole 6, and it can be used as a compass Draw a circle.

Abstract

The invention relates to a multipurpose mathematical teaching aid and belongs to teaching aids. The multipurpose mathematical teaching aid comprises an angle measuring circular plate and rulers and is characterized in that the angle measuring circular plate is of 360 degrees. A circle center shaft is mounted on the angle measuring circular plate. The angle measuring circular plate is connected with the two rulers through the circle center shaft. The rulers can form optional included angles by using the circle center shaft as the axis, and the included angles can be measured by the angle measuring circular plate. A movable groove is formed in one of the rulers. A movable clamp is mounted on the movable groove. A chalk clamp hole is formed in the middle of the movable clamp. The multipurpose mathematical teaching aid has the advantages that the teaching aid is integrated with the functions of a set square, an angle gauge, a ruler and a compass; when the teaching aid is used as the compass, a chalk is clamped in the chalk clamp hole, the circle center shaft is set at the preset position, and an arc can be drawn by moving the chalk clamp hole; during angle measuring, a user only needs to use the two rulers as the two edges, and the teaching aid is convenient and practical.

Description

technical field [0001] The invention relates to a teaching aid, in particular to a multipurpose mathematics teaching aid. Background technique [0002] Among the existing mathematics teaching aids, settable, ruler, protractor, and compass are all single tools, which are inconvenient to use and carry. Inaccurate, seriously affecting the quality of teaching. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multipurpose mathematical teaching aid with the functions of a triangle ruler, a protractor, a ruler and a compass at the same time, so as to facilitate teaching and improve teaching quality. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is a multi-purpose mathematical teaching aid, which includes a measuring angle disc and a scale ruler. It is characterized in that the measuring angle disc is 360 degrees, and the circle center is inst...
