Abstract
The utility model relates to a teaching aid used in geometry and mathematics teaching in primary and middle schools. The specific technical scheme is that: the geometry and mathematics teaching aid consists of six straight scales, the four of which have the same length and are relatively long while the other two are shorter; the scales are made of transparent plastic material and one side of each scale is marked with calibration; magnets at two ends are embedded inside the plastic; the magnetic direction of the magnets is vertical to the length direction of the straight scales, the two ends of N-pole and S-pole of the magnet are inverted with each other; wherein, one of the longer straight scales is provided with protractor calibration, one is provided with geometric figure holes such as round, oval, triangle, rectangle, polygon. The teaching aid has simple production, low cost, convenient use, direct viewing and visual pattern and wide application, and is an exploring design and a good teaching aid for training children for imagination and creative thinking ability.
Description
Technical field
The utility model relates to a kind of teaching aid, especially the teaching aid that uses in the geometry mathematical education of middle and primary schools.
Background technology
In the teaching in primary school, junior middle school, high medium each stage, understand in order to help the student, the teacher usually will use the teaching aid of various models.Particularly in the teaching of the plane of mathematics subject, solid geometric pattern, can not lack the teaching aid of various geometric configuratioies more.But existing mathematics teaching aid model, iron wire commonly used is welded into solid shape, and not only quality is big, and the cost height carries inconvenience, and each structure all need make corresponding model, thereby quantity is more, also brings inconvenience to storage.
The utility model content
The purpose of this utility model is the deficiency that overcomes the above-mentioned background technology, and a kind of improvement of mathematical education teaching aid is provided, and this teaching aid should be able to assemble the required various models of how much mathematical educations neatly, has simple in structure, easy accessibility, is convenient to stowable characteristics.
The technical scheme that the utility model proposes is: how much mathematics teaching aids, comprise the some straight board foots of rectangle, and the two ends of every straight board foot are embedded with a magnet.
Above-mentioned straight board foot can be plastic material, and it has scale on one side, and the magnet at its both ends is embedded in plastics inner, and the magnetic force of magnet is to vertical with the length direction of straight board foot, and the magnet N utmost point S extreme direction at both ends is put upside down each other.The color of straight board foot plastics can be Transparent color, also can be colour.
The radical of straight board foot can be 6, wherein 4 long and isometric, in addition two shorter.Radical also can be more.Generally just can form multiple patterns such as triangle, various quadrilateral, pentagon, hexagon, tetrahedron by 6 that say above.
The straight board foot of band scale can be used alone as ruler amount length.
In order to enrich the purposes of this mathematics teaching aid, can also in described straight board foot, be arranged to rare one and have the protractor scale, have geometric figure holes such as circle, ellipse, triangle, quadrilateral, polygon above having one at least.
When using this mathematics teaching aid composite figure, need only the end overlaid with every straight board foot, promptly reliable magnetic force adhesion forms contact.The time spent is not as long as take it apart parallel placement.And the storing state after taking apart takies minimum space, collects very convenient.
This has magnet above teaching aid, so also can be used for physics teaching.
This teaching aids making is simple, and is cheap, easy to use, visual in image, and the scope of application is extensive, is the teaching aid of a kind of good teaching aid and inquiry design for imagination of cultivating children and creative thinking ability.
Description of drawings
Fig. 1 is a straight board foot structural front view of the present utility model.
Fig. 2 is a straight board foot vertical view of the present utility model.
Among the figure, 1. magnet, 2. scale, 3. geometric figure hole.
Embodiment
This geometry mathematics teaching aid is made up of 6 straight board foots, wherein 4 long and isometric, in addition two shorter.Described straight board foot is the transparent plastic material, and it has scale (2) on one side, and the magnet at its both ends (1) is embedded in plastics inner, and the magnetic force of magnet (1) is to vertical with the length direction of straight board foot, and the magnet N utmost point S extreme direction at both ends is put upside down each other.Have the protractor scale on the wherein long straight board foot, have geometric figure holes (3) such as circle, ellipse, triangle, quadrilateral, polygon above the straight board foot.
Claims (4)
1. how much mathematics teaching aids is characterized in that this geometry mathematics teaching aid comprises the some straight board foots of rectangle, the two ends of every straight board foot are embedded with a magnet.
2. several teaching teaching aid according to claim 1, it is characterized in that described straight board foot is a plastic material, it has scale on one side, and the magnet at its both ends is embedded in plastics inner, the magnetic force of magnet is to vertical with the length direction of ruler, and the magnet N utmost point S extreme direction at both ends is put upside down each other.
3. several teaching teaching aid according to claim 1 and 2 is characterized in that described straight board foot has 6, wherein 4 long and isometric, in addition two shorter.
4. several teaching teaching aid according to claim 2 is characterized in that having at least one to have the protractor scale in the described straight board foot, has geometric figure holes such as circle, ellipse, triangle, quadrilateral, polygon above having one at least.
