[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] Embodiment 1, as Figure 1-3 As shown, a multifunctional mathematics learning teaching aid is used. The teaching aid adopts a magnetic blackboard 1 and a teaching aid to achieve a combination effect, thereby achieving a multifunctional teaching effect. The outer wall of the magnetic blackboard 1 utilizes a multifunctional drawing ruler 4 and a marking magnetic block 2 that are magnetically adsorbed. The marking magnetic block 2 can be used to mark figures and formulas on the blackboard, which plays a good auxiliary role. The multifunctional drawing ruler 4 utilizes two sets of forked rulers 11 and a measuring disk 10 to measure and draw figures of any angle. When it is necessary to draw a figure with an angle, since the forked ruler 11 is connected to the multifunctional drawing ruler 4 through a connecting shaft 15, the two sets of forked rulers 11 can be rotated to adjust the angle between the two sets of forked rulers 11. The calibration line 14 on the outer surface of the ruler 11 is aligned with the scale line on the measuring disk 10, so it can be adjusted to the required angle. The length of the side of the figure can be determined by the measuring scale 12 on the forked ruler, which is convenient for measurement and calculation. At the same time, the multifunctional drawing ruler 4 also has the function of drawing a circle. A chalk 16 is installed at the chalk installation slot 13 at the front end of the forked ruler 11, and the chalk 16 is aligned with the surface of the blackboard. The forked ruler 11 is rotated along the connecting shaft 15 to draw a circle, so that the teaching aid is comprehensive and more practical. The multifunctional drawing ruler 4 is adsorbed on the outer surface of the magnetic blackboard 1 by the magnetic block 17. When using it, the teacher no longer needs to lift the drawing tool to use it, making the teacher's teaching process easier.

[0023] Embodiment 2, as Figure 1-4 As shown, a multifunctional mathematics learning teaching aid, a magnetic blackboard 1 is connected to a teaching aid placement cabinet 6 at the lower end, so that the teacher's teaching aids and teaching materials can be classified and stored, making the overall storage more convenient. The drawer 7 at the upper end of the teaching aid placement cabinet 3 can be used for small objects such as chalk. The universal wheel 9 at the bottom of the teaching aid placement cabinet 6 can be easily pushed to move the teaching aid placement cabinet 6 and the magnetic blackboard 1, which facilitates the movement and transportation of teaching aids and reduces the workload of teachers.

[0024] How it works

[0025] It should be noted that the utility model is a multifunctional mathematics learning teaching aid. When in use, the outer wall of the magnetic blackboard 1 utilizes the multifunctional drawing ruler 4 and the marking magnetic block 2 which are magnetically adsorbed. The marking magnetic block 2 can be used to mark figures and formulas on the blackboard. The multifunctional drawing ruler 4 utilizes two sets of forked rulers 11 and a measuring disk 10 to measure and draw figures of any angle. When it is necessary to draw figures with angles, since the forked ruler 11 is connected to the multifunctional drawing ruler 4 through a connecting shaft 15, the two sets of forked rulers 11 can be rotated to adjust the angle between the two sets of forked rulers 11. The calibration line 14 on the outer surface of the forked ruler 11 is aligned with the scale line on the measuring disk 10 to adjust to the desired angle. The measuring scale 12 on the forked ruler can determine the length of the side of the figure, which is convenient for measurement and calculation. At the same time, the multifunctional drawing ruler 4 also has the function of drawing a circle. A chalk 16 is installed at the chalk installation slot 13 at the front end of the forked ruler 11, and the chalk 16 is aimed at the surface of the blackboard. The forked ruler 11 is rotated along the connecting shaft 15 to draw a circle. The magnetic blackboard 1 is connected to the teaching aid placement cabinet 6 at the lower end, so that the teacher's teaching aids and teaching materials can be classified and stored. The drawer 7 at the upper end of the teaching aid placement cabinet 3 can be used for small objects such as chalk. The universal wheel 9 at the bottom of the teaching aid placement cabinet 6 can easily push the teaching aid placement cabinet 6 and the magnetic blackboard 1 to move, which is convenient for the movement and transportation of teaching aids.
