Abstract
A functional image demonstrating instrument comprises a plate body having a coordinate system. The technical main points of the functional image demonstrating instrument are that the surface of the plate body is provided with criss-cross slide grooves; points of intersection of the horizontal and vertical slide grooves are coordinate points of the coordinate system; the slide grooves are provided with fixing blocks through slide blocks, and the fixing blocks are provided with wire holes through which a function simulation wire can pass, and the fixing blocks can be moved to any coordinate point along the horizontal and vertical slide grooves. When one function curve needs to be demonstrated, each fixing block can be moved along the horizontal and vertical slide grooves to a position of a required coordinate value, then each fixing block is fixed at the position of the required coordinate value, and the function simulation wire sequentially passes through the wire hole of each fixing block, and thus the function curve is formed and the function simulation wire is used to represent a functional image. When the functional image needs to be changed, each fixing block can be moved to a position of a selected coordinate value without re-threading the function simulation wire. The functional image demonstrating instrument is simple and convenient to operate and improves the teaching efficiency of a teacher.
Description
Technical field:
The utility model relates to a kind of teaching apparatus for mathematics, is specifically related to a kind of functional image demonstrator.
Background technology:
Function is the important content in the mathematical education, because its principle is more abstract, make the student understand difficulty, so just increased teacher's the difficulty of giving lessons, and the content about function does not have special teaching demonstration instrument in the existing mathematical education, can't improve teacher's the efficient of giving lessons.
Publication number is that the document of CN202816216U discloses the utility model patent that a kind of name is called the functional image demonstration board, can demonstrate out by stretch cord the track of function, need not teacher's Freehandhand-drawing functional image, also be convenient to simultaneously student's understanding, but in the time will changing the function track, stretch cord must be taken out, again penetrate in the rubber ring of other coordinate figure of expression, its operation is more loaded down with trivial details again, and it is convenient not to use.
The utility model content:
The purpose of this utility model provides a kind of functional image demonstrator, and its structural design advantages of simple, convenient to use, time saving and energy saving makes things convenient for the teacher to carry out the mathematical function teaching, has improved student's learning interest.
The purpose of this utility model is achieved in the following ways: this functional image demonstrator, comprise the plate body with coordinate system, the technical scheme that adopts is: described plate body surface is provided with crisscross chute, intersection point to chute is the coordinate points of coordinate system in length and breadth, be provided with fixed block by slide block on the chute, fixed block is provided with and can holds the through wires hole that the functional simulation line passes.
The beneficial effects of the utility model are: this functional image demonstrator, fixed block can move along carrying out the optional position to chute in length and breadth, so just be movable on any one coordinate points, in the time will representing a certain function curve, can be with each fixed block by the slide block on it along position from the denotation coordination value of choosing to the chute of laying that adjust in length and breadth, after each fixed block being fixed on the position of each coordinate figure of choosing, the functional simulation line is passed successively the through wires hole of each fixed block, thereby the formation function curve comes the representative function image with the functional simulation line.In the time will changing functional image, can move arbitrarily the coordinate figure place that chooses after each fixed block arrives and get final product, need not the extraction of functional simulation line is penetrated again again, it is simple and efficient to handle, has improved teacher's the efficient of giving lessons.The utility model structural design advantages of simple, convenient to use, time saving and energy saving makes things convenient for the teacher to carry out the mathematical function teaching, has improved student's learning interest.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the interior structural representation of chute that fixed block of the present utility model is installed in horizontal laying.
Embodiment:
See figures.1.and.2, this functional image demonstrator, comprise the plate body 1 with coordinate system, it is characterized in that: described plate body 1 surface is provided with crisscross chute 4, intersection point to chute 4 is the coordinate points of coordinate system in length and breadth, be provided with fixed block 2 by slide block 5 on the chute 4, fixed block 2 is provided with and can holds the through wires hole 3 that functional simulation line 6 passes.
