Abstract
The invention discloses a child mathematics teaching aid, and aims to provide a teaching aid with better graphic teaching effect. The invention comprises a sliding block and a sliding rail, wherein the sliding block is in sliding fit with the sliding rail. The sliding block is a cuboid, and sliding grooves corresponding to the sliding rails are formed in the two sides of the sliding block; the cross section of the slide rail is rectangular, an opening is arranged above the rectangle, and the sliding chutes on the sliding block are embedded at two sides of the opening of the slide rail; the slide rail is fixed on the shell. According to the technical scheme, the rectangular sliding block is adopted, and sliding grooves in the sliding block are embedded in two sides of an opening of the sliding rail. Therefore, the slide block can only perform directional sliding, namely translation, and the plane is kept not to be overturned. When the sliding blocks are moved, only the surface of the sliding blocks is pushed by fingers, so that when the distance between the sliding rails is closer, the gaps between the sliding blocks are very small, and the graph formed by the sliding blocks has good continuity, strong sense of unity, vivid image and easy acceptance by infants.
Description
Technical field
The present invention relates to a kind of teaching aid, especially infant mathematics teaching aid.
Background technology
At present, preschool education more and more comes into one's own, in mathematical education, traditional teaching aid mainly is to adopt abacus, counts teaching by plectrum, owing to be subjected to the restriction of teaching aid, the content of courses is not abundant, and when organizing figure, the globality and the continuity of figure are relatively poor, cause institute's composition vivid, not lively, the child is difficult for accepting.
Summary of the invention
The objective of the invention is, the defective at prior art exists provides a kind of diagram teaching efficiency better infant mathematics teaching aid.
Technical scheme of the present invention is: comprise slide block and slide rail, slide block and slide rail are slidingly matched.Described slide block is a rectangular parallelepiped, and the slide block both sides are provided with and the corresponding chute of slide rail; The xsect of slide rail is a rectangle, and rectangular top is provided with opening, and the chute on the slide block is embedded in slide rail opening part both sides; Slide rail is fixed on the housing.
Adopt the rectangle slide block in the technical solution of the present invention, the chute on the slide block is embedded in slide rail opening part both sides.Therefore, slide block can only be done directed the slip, i.e. translation keeps the plane can not overturn.During moving slider, only with hand refers to that the surface that promotes slide block gets final product, and therefore, the distance between the slide rail can be done very closely, and the gap between each slide block is very little, and the figure continuity of being made up of slide block is good, and associative perception is strong, and is vivid, is easy to be accepted by the child.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further detail, but does not constitute any limitation of the invention.
Fig. 1 is the front view of the embodiment of the invention;
Fig. 2 is that the A of Fig. 1 is to view.
Embodiment
Fig. 1, shown in Figure 2 the present invention includes slide block 2 and slide rail 3.Described slide block 2 is a rectangular parallelepiped, also can make square, and slide block 2 both sides have chute, and this chute is corresponding with slide rail 3.The xsect of slide rail 3 is hollow rectangle, and there is opening this hollow rectangular top, and the chute on the slide block 2 is embedded in slide rail 3 opening part both sides, and slide block 2 is relative with chute to be slidingly matched.Slide rail 3 is screwed on housing 1 base plate.Make slide block 2 along slide rail 3 slips separately with each slide block 2 surface of finger push during operation, because all there is slideway slide block 2 both sides, slide block 2 positions are more neat when stationary state, and the slit is less between the slide block 2, the figure associative perception of being made up of slide block 2 is strong, and vivid being easy to accepted by the child.
Claims (1)
