Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with accompanying drawing embodiment:

[0015] Such as figure 1 The demonstration teaching aid for translation and rotation shown includes a panel 1 drawn with 10 × 10 array grids, grid lines 2 are wound on the panel 1 according to the grid, and placed between the grid lines 2 and the panel 1 There are 4 graphics cards 3, and the graphics cards 3 are geometric figure collage cards, and symbols are marked on the graphics cards 3, such as symbols ☆, ◇, △ on one of the graphics cards; symbols A, B on one graphics card , C.

[0016] The present invention allows children to translate the graphic card 3 by hand, observe the position change of the graphic card 3 before and after the translation, and how many grids the graphic card 3 marked with symbols ☆, ◇, △ is translated in the horizontal direction, and the symbol ☆ on it Also translate the same number of grids in the horizontal direction, such...

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 [0001] The invention relates to the technical field of primary school mathematics teaching aids, in particular to a teaching aid for demonstrating graphic translation and rotation. Background technique [0002] Because children are active and have a short attention span, drawing pictures on the blackboard with chalk to explain the translation and rotation of graphics will make children feel very boring in learning. There is no demonstration teaching aid for children to gain intuitive perceptual knowledge, and it is difficult to concentrate children's attention , the teaching effect is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a translation and rotation demonstration teaching aid to solve the problem that the existing graphics translation and rotation teaching is boring, it is difficult for children to obtain intuitive perceptual knowledge, and the teaching effect is poor. [0004] In ...
