Abstract
The utility model discloses a drawing board for mathematics teaching. The drawing board for mathematics teaching comprises a circular bottom board; the middle part of the circular bottom board is provided with a circular hole; a transparent board is arranged on the circular hole and is of a round shape; a positioning bolt is arranged at the centre of the transparent board and is provided with a pointer; the external circumference of the circular hole is marked with an angle scale of 0-360 DEG; the circular bottom board is internally provided with a square long hole; and two sides of the square long hole are marked with scale lines. The drawing board for mathematics teaching can be used for measuring angles and has multiple functions and high level of integration; triangles, line segments and circles in class can be drawn and straight lines having various angles with a reference line can be drawn by teachers without using a large number of drawing tools; and the drawing board for mathematics teaching can be used for simplifying drawing operation and is convenient for mathematics teaching and suitable for popularization and use.
Description
Technical field
The utility model belongs to the educational outfit technical field, is the drawing board that a kind of mathematical education is used specifically.
Background technology
In the mathematical education process, drawing instrument is the requisite instrument on class of mathematics teacher.The mathematics teacher need draw various figures such as coordinate diagram, form, circle on blackboard.On the classroom, the teacher often draws with feel for fast, causes figure inaccurate, also not attractive in appearance like this.In order to draw chart etc. more regular, writing on the blackboard is attractive in appearance, and the teacher often will be with various drawing instruments such as ruler, set square, compasses etc. at school the time; So very trouble has increased the weight of teacher's burden, but also will delay a lot of times; Many chapters and sections of chart particularly; Just need constantly wipe then repainting, have a strong impact on teaching process like this, also increase teacher's working strength when having reduced efficiency of teaching.And; When need iso-surface patch becomes the straight line of various angles with line of reference on blackboard, must use the various teaching aids that comprise ruler, compasses, angel measuring instrument etc. simultaneously, drawing process is very complicated; And the part angle can't identify, and is not suitable for on-the-spot writing on the blackboard and uses.
Therefore, designing the drawing board that a kind of multi-functional, simple and light, easy to use, portable mathematical education uses is a problem of needing solution badly.
The utility model content
The purpose of the utility model provides a kind of mathematical education easy and simple to handle when mathematical education, the drawing standard and uses drawing board; Its integrated level is high; Can be used in and draw triangle, circle, line segment figures on the classroom, and the drafting of carrying out various angle straight lines, be fit to numerous mathematics teachers and use.
The technical scheme of the utility model is:
A kind of mathematical education is used drawing board, comprises circular bottom plate, opens circular hole at the circular bottom plate middle part; Transparent panel is installed on the circular hole, and transparent panel is circular, transparent panel circle centre position installing and locating bolt; Pointer is installed on the bolt; Be marked with 0～360 degree angle index on the excircle of circular hole, a square slotted hole is arranged in said circular bottom plate, square slotted hole both sides indicate graduation mark.
As optimal technical scheme, the utility model is characterised in that said circular bottom plate is provided with five and refers to groove.When graphing, finger can be pushed down the finger groove like this, firmly controls drawing board, prevents that it from moving, the more standard of drawing.
As optimal technical scheme, the utility model is characterised in that and has right angled triangle, equilateral triangle, circular or oval-shaped hole in the said circular bottom plate.Can draw right angled triangle, equilateral triangle, circular or oval so easily.
As optimal technical scheme, the utility model is characterised in that said circular bottom plate adopts transparent plastic sheet to make.
As optimal technical scheme, the utility model is characterised in that said circular bottom plate is provided with and mounts the hole, said mount to be provided with in the hole mount stay cord.
The beneficial effect of the utility model is:
The utility model can take measurement of an angle, diverse in function, and integrated level is high; Can on the classroom, draw triangle, line segment and circle, and can draw the straight line that becomes various angles with line of reference, need not the teacher and use a large amount of drawing instruments; Simplify mapping operation, be convenient to mathematical education and use.
In a word, the utility model is simple in structure, in teaching process, can easily draw, and alignment easy and simple to handle, easy has improved teaching efficiency.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment 1;
