Abstract
The invention relates to a teaching aid capable of being combined into multiple geometrical shapes. The teaching aid is in a ruler shape; two ends of the teaching aid are provided with grooves and tongues and are circular-arc-shaped. The teaching aid is simple in structure, convenient to carry, small in storage occupation space, low in cost, rapid in combination, magic and strong in practicability and is an ideal teaching aid which enables beginners in preschool education or elementary education to understand intuitively.
Description
Technical field
The present invention relates to a kind of teaching aid, more specifically say a kind of plane geometry teaching aid.
Background technology
Beginner in preschool education or primary school education, need to be to geometric understanding and recoganization and study such as angle, triangle, quadrilateral and polygons, good results of learning are by means of object teaching, allow the student sharpen understanding and be familiar with, and at present quadrangular teaching aid is arranged, Multifunctional quadrangular teaching aid and mathematics teaching aid etc., the convertible multiple difform quadrilateral of quadrangular teaching aid, visual in image, but complex structure can only be transformed into quadrilateral, the combination trouble, the teaching that is not suitable for the beginner is used; Multifunctional quadrangular teaching aid, visual in image though the teaching aid function is more, complex structure can only be transformed into quadrilateral, troublesome poeration, the teaching that is not suitable for the beginner is used; Mathematics teaching aid, though dexterously set square, protractor and compasses are combined, but the complex structure that seems concerning the beginner, troublesome poeration, the figure that combines are more, and the beginner is difficult for the intuitivism apprehension geometric figure, is not suitable for beginner's use of imparting knowledge to students.
Summary of the invention
The objective of the invention is: design a kind of teaching aid that can make up multiple geometric configuration, simple in structure, processing ease, can make the beginner understand the shape of multiple plane geometry visual in imagely, strengthen student's manipulative ability, improve the student to the learning interest of geometric knowledge, also can effectively overcome the defective in the background technology.
Realization the technical solution used in the present invention is: this teaching aid is the ruler shape, and there is tongue and groove at two ends and is circular arc.
In order by the magnetic attraction overlapping mode ruler to be combined into the teaching aid of geometric configuration, the tongue and groove separation at these teaching aid two ends is provided with circular magnetic sheet and breach in the both sides of this teaching aid at the tongue and groove place at these teaching aid two ends.
Good effect of the present invention is: simple and practical, make easy, with low cost, combination is quick and have the magic color, easy to carry, deposit take up room little, not only can be overlapped to form long ruler, can make up the teaching aid of multiple geometric configuration, and can make the beginner see intuitively multiple geometric configuration object, sharpen understanding and be familiar with, with the manipulative ability that improves the student with to the learning interest of geometric knowledge.
Description of drawings
Accompanying drawing 1 is front view of the present invention;
Accompanying drawing 3 is the triangular structure synoptic diagram that are combined into the present invention.
Embodiment
The present invention is shown in accompanying drawing 1,2, this teaching aid is the ruler shape, there is tongue and groove 2 at two ends and is circular arc, in order to be combined into the teaching aid of multiple geometric configuration by the connected mode that attracts overlap joint, tongue and groove 1 separation at these teaching aid two ends is provided with magnetic sheet 2 and breach 3 in the both sides of this teaching aid at the tongue and groove place at these teaching aid two ends.
The method that this teaching aid makes up multiple geometric configuration teaching aid is: this teaching aid is with tongue and groove 1 and tongue and groove 1 overlap joint but must make up (as shown in Figure 3) by the method for attachment of the head and tail overlap joint of this teaching aid, with same bridging method, with this teaching aid also triangle that meets at right angles capable of being combined, tiltedly quadrilateral, rhombus, trapezoidal, right-angled trapezium, pentagon and polygon etc.
Claims (2)
1. teaching aid that can make up multiple geometric configuration is characterized in that: it is the ruler shape, and there is tongue and groove at two ends and is circular arc.
2. described a kind of teaching aid that can the multiple geometric configuration of combination according to claim 1, it is characterized in that: there is tongue and groove separation at described two ends in these teaching aid both sides, and there are circular magnetic sheet and breach in the tongue and groove place.
