Abstract
The invention discloses a translation and rotation demonstrating teaching aid and relates to the technical field of teaching aids for primary school mathematics. The teaching aid comprises a panel, wherein a plurality of array boxes are drawn on the panel. Box lines wind around the panel according to the boxes. A plurality of graph cards are arranged between the box lines and the panel. The graph cards are geometric graph collage cards and are labeled with symbols. Compared with the prior art, a child moves the graph cards horizontally with the hands, observes the position change of the graph cards before and after translation is carried out, slowly rotates the graph cards around a certain point, observes the position change of a certain part of the graph cards before and after rotation is carried out, and therefore obtains visual perceptual knowledge, the learning interest of the child is motivated, and the teaching effect is improved.
Description
Technical field
The present invention relates to math teaching tool for primary school technical field, especially a kind of teaching aid for Presentation Graphics translation and rotation.
Background technology
Because children are active, the time of visual cognitive ability is short, to draw the explanation translation of figure and rotation with chalk on blackboard, children for learning can feel very uninteresting, do not have demonstration teaching aid to allow children obtain perceptual knowledge intuitively, be difficult to the notice concentrating children, teaching efficiency is poor.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of translation and rotating display teaching aid, uninteresting with rotation teaching to solve existing figure translation, is difficult to allow children obtain perceptual knowledge intuitively, and the problem causing teaching efficiency poor.
In order to solve the problem, the technical solution used in the present invention is: comprise the panel being decorated with multiple array grids, and described panel is wound with mesh lines by described grid, is provided with multiple figure card between described mesh lines and described panel.
In above-mentioned translation and rotating display teaching aid technical scheme, technical scheme can also be more specifically: described figure card is geometric figure pasteup card.
Further, symbol is marked with at described figure card subscript.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, the present invention starts translation figure card by allowing children, observe the change in location of figure card before translation and after translation, figure card is translation or vertically translation how many lattice in the horizontal direction, also translation or the identical lattice number of vertically translation in the horizontal direction of a point on figure card; Slowly rotated around some points by figure card, certain part of observing figure card rotates the change in location of front and back, and allow children obtain perceptual knowledge intuitively, excite the learning interest of children, the phenomenon of correct difference translation and rotation, improves teaching efficiency.
2, figure card is geometric figure pasteup card, can concentrate the notice of children.
3, be marked with symbol at figure card subscript, make children observe the translation of graphics card sheet and rotation phenomenon more clear.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the schematic diagram after the figure card translation in Fig. 1.
Fig. 3 is a postrotational schematic diagram of figure card in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
A kind of translation as shown in Figure 1 and rotating display teaching aid, comprise the panel 1 being decorated with 10 × 10 array grids, panel 1 is wound with mesh lines 2 by grid, 4 figure cards 3 are placed with between mesh lines 2 and panel 1, figure card 3 is geometric figure pasteup card, is marked with symbol at figure card 3 subscript, as symbol ☆ put on by a figure card wherein, ◇, △; A figure card puts on symbol A, B, C.
The present invention starts translation figure card 3 by allowing children, observes the change in location of figure card 3 before translation and after translation, will indicate symbol ☆, ◇, figure card 3 translation how many lattice in the horizontal direction of △, the lattice number that also translation is identical in the horizontal direction of the symbol ☆ on it, as shown in Figure 2; To indicate symbol A, the figure card 3 of B, C slowly rotates around A point, observes the B on it, the change in location before and after C point rotates, as shown in Figure 3; Allow children obtain perceptual knowledge intuitively, excite the learning interest of children, the phenomenon of correct difference translation and rotation, improves teaching efficiency.
Claims (3)
1. a translation and rotating display teaching aid, it is characterized in that: comprise the panel (1) being decorated with multiple array grids, described panel (1) is wound with mesh lines (2) by described grid, between described mesh lines (2) and described panel (1), is provided with multiple figure card (3).
2. translation according to claim 1 and rotating display teaching aid, is characterized in that: described figure card (3) is geometric figure pasteup card.
