Abstract
The invention relates to a teaching aid used in geometry and mathematics teaching in primary and middle schools. According to the specific technical scheme, the geometry and mathematics teaching aid consists of six straight scales, the four of the six straight scales have the same length and are relatively longer 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; 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 advantages of 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 present invention relates to a kind of teaching aid, the teaching aid especially using 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, in order to help student to understand, teacher usually will use the teaching aid of various models.Particularly, in the teaching of the plane of Mathematics Discipline, solid geometric pattern, more can not lack the teaching aid of various geometric configuratioies.But existing mathematics teaching aid model, conventional iron wire is welded into solid shape, and not only quality is large, and cost is high, carries inconvenience, and each structure all needs to make corresponding model, thereby quantity is more, also brings inconvenience to storage.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned background technology, a kind of improvement of mathematical education teaching aid is provided, 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 feature.
The technical scheme that the present invention proposes is: mathematics teaching aid, 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, another two shorter.Radical also can be more.Generally just can form the multiple patterns such as triangle, various quadrilateral, pentagon, hexagon, tetrahedron by 6 that say above.
Can be used alone as ruler amount length with the straight board foot of scale.
In order to enrich the purposes of this mathematics teaching aid, can also, in described straight board foot, arrange and have one at least with protractor scale, have one at least above with geometric figure holes such as circle, ellipse, triangle, quadrilateral, polygons.
While using this mathematics teaching aid composite figure, as long as by the end overlaid of every straight board foot, reliable magnetic force adhesion, forms contact.The used time is not as long as taken apart parallel placement.And the storing state after taking apart takies minimum space, collect very convenient.
Above this teaching aid, there is magnet, therefore also can be used for physics teaching.
This teaching aids making is simple, cheap, easy to use, visual in image, applied widely, is the teaching aid of a kind of good teaching aid and inquiry design for imagination and the creative thinking ability of cultivating children.
Accompanying drawing explanation
Fig. 1 is straight board foot structural front view of the present invention.
Fig. 2 is straight board foot vertical view of the present invention.
In figure, 1. magnet, 2. scale, 3. geometric figure hole.
Embodiment
This mathematics teaching aid is made up of 6 straight board foots, wherein 4 long and isometric, another two shorter.Described straight board foot is transparent plastic material, and it has scale (2) on one side, and the magnet (1) at its both ends 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.Wherein on long straight board foot with protractor scale, above a straight board foot with geometric figure holes (3) such as circle, ellipse, triangle, quadrilateral, polygons.
Claims (2)
1. mathematics teaching aid, is characterized in that this mathematics teaching aid comprises the some straight board foots of rectangle, and the two ends of every straight board foot are embedded with a magnet.
2. according to the mathematics teaching aid described in claim 1, it is characterized in that described straight board foot is 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.
