Abstract
A function demonstration template mainly comprises a magnetic panel, a parabola template and a straight line template, wherein a cross coordinate system is printed on the magnetic panel and provided with scales; the parabola template is of a transparent magnetic sheet, and a parabola and scales are printed on the template; the straight line template is of a transparent magnetic sheet, and a straight line and scales are printed on the template; and the parabola template as well as the straight line template and the magnetic panel attract with one another by means of magnetism and can move or rotate mutually. The function demonstration template is simple to operate without the need of manual drawing, has a good demonstration effect and low manufacturing cost, and is convenient for teachers to teach the function part.
Description
Technical field
The utility model relates to the teaching aid technical field, relates in particular to a kind of function demonstration template that is used for the function explanation.
Background technology
At present; The explanation of in the mathematical education process, often need on blackboard, mapping is demonstrated, especially function explanation, and mapping becomes important supplementary means; But the method that present math teacher mainly adopts is manual drawing; Hand-held ruler of teacher and chalk are drawn on blackboard repeatedly, and operation very bothers, wastes time and energy like this, has increased work difficulty to the teacher.
Summary of the invention
The purpose of the utility model provides a kind of function demonstration template, this function demonstration template do not have draw by hand, easy to use, simple to operate, good demonstration effect, advantage of low manufacturing cost.
The purpose of the utility model realizes as follows: this function demonstration template, mainly comprise magnetic panel, para-curve template, straight line template, and be printed on the cross coordinate system on the magnetic panel, attaching on the cross coordinate system has scale; The para-curve template is transparent magnetic flakes, and is printed on para-curve and scale on the template; The straight line template is transparent magnetic flakes, and is printed on straight line and scale on the template; Rely on magnetic to adsorb each other between para-curve template and straight line template and the magnetic panel, can move each other or rotate.
The utility model is not drawn by hand, and is simple to operate, good demonstration effect, low cost of manufacture.Made things convenient for the teaching of teacher's function part.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
With reference to Fig. 1, the utility model comprises magnetic panel 1, para-curve template 2, straight line template 3, is printed on cross coordinate system 4 on the magnetic panel 1, and attaching on the cross coordinate system 4 has scale; Para-curve template 2 is transparent magnetic flakes, and is printed on para-curve and scale on the template; Straight line template 3 is transparent magnetic flakes, and is printed on straight line and scale on the template; Rely on magnetic to adsorb each other between para-curve template 2 and straight line template 3 and the magnetic panel 1, and can move each other or rotate.
