Abstract
The utility model provides a mathematics teaching aid capable of changing multi shapes, which is used for the mathematics teaching in middle schools, comprising six long-bar plates. The both ends of each long-bar plate are respectively provided with bolt holes, and three of six long-bar plates are provided with slideways and are connected with the other three long-bar plates having no slideways by bolts. The utility model solves the problems that the prior art has single teaching aid and inconvenient teaching.
Description
Technical field:
The utility model relates to the mathematics teaching aid of the multiple shape of a kind of conversion that a kind of middle-school mathematics teaching uses.
Background technology:
It is fewer to exist teaching aid in the middle-school mathematics teaching at present, teaching aid is single, the problem that is not easy to impart knowledge to students, the inventor according in the middle-school mathematics teaching in saying trigonometry the teacher of relevant multiple shape just on blackboard, draw various relevant shapes, make the student feel uninteresting, if the teacher stroke ties full mathematics teaching aid with material object mutually saying that mathematics teaching aid that the imagination of inventor after class can design the multiple shape of a kind of conversion just can solve in the mathematical education.
The utility model content:
In order to overcome problems of the prior art, the utility model provides the mathematics teaching aid of the multiple shape of a kind of conversion, and this teaching aid connects with bolt by six block length battens, and every batten is removable, through drawing, push away the mathematics teaching aid that becomes multiple shape.
The technical scheme that the utility model technical solution problem is adopted is: the inventor according to math teacher after relevant triangle in the trigonometry is said in the classroom, whether be transformed into the teaching aid of multiple shape according to the teaching needs how good this is thinking to combine with rectangular plate, through developing the mathematics teaching aid that makes convertible multiple shape repeatedly, this teaching aid is to make six block length battens with plank or hard plastic board, in the three block length battens therein, being provided with slideway (drawing the slanted bar section) in the middle of every block length bar links into an integrated entity six block length battens with bolt, bolt can slide along slideway, and slideway is 1.0～1.5cm apart from the bolt hole distance at every block length batten two ends.This teaching aid can be gently once drawing or one pushing away variable swap out multiple shape such as hexagon, trapezoidal, quadrilateral, parallelogram, isosceles triangle, right-angle triangle, oxygon, obtuse triangle, square, pentagon etc.
The utility model beneficial effect is: simple in structure, and convenient teaching, economical and practical, convertible multiple shape can improve student's perceptual knowledge during teaching, improve student's results of learning and teaching efficiency.
Description of drawings:
Fig. 1 is the utility model one-piece construction synoptic diagram.
Fig. 2 is trapezoidal, quadrilateral conversion pictorial diagram.
Fig. 3 is isosceles triangle, right angle trigonometry fractal transform pictorial diagram.
Among the figure 1, bolt, 2, rectangular plate, 3, slideway.
Embodiment:
In Fig. 1, be bolt 1 with the thin bolt of buying, make six block length battens 2 with wood lath or hard plastic board again, be respectively equipped with bolt hole at every block length batten two ends and be provided with slideway 3 in the three block length battens therein, slideway 3 is 1.0～1.5cm with the bolt hole distance.Connect and compose the mathematics teaching aid of the multiple shape of a kind of conversion, convertible multiple shape with being provided with three of slideway 3 in the six block length battens at interval with bolt with three block length battens of no slideway.
In Fig. 2, for this teaching aid can be transformed into: base (going to the bottom) is that the rectangular plate 2 of a band slideway 3 and the rectangular plate 2 of a no slideway are formed, the top is forming with a rectangular plate 2 by slideway of a no slideway, and two hypotenuses are respectively one and form trapezoidal by slideway with the rectangular plate of a no slideway; Quadrilateral respectively is that 2 block length battens (have, a no slideway) are formed by last bottom, and the right and left is respectively one slideway 3, and the rectangular plate 2 of a no slideway is formed.
In Fig. 3, this teaching aid can be transformed into: isosceles right triangle: every limit, three limits is made up of a rectangular plate 2 that is provided with a slideway 3 and a no slideway; Right-angle triangle: hypotenuse is that three block length battens 2 are formed, wherein two are one and are made up of with the rectangular plate by slideway for the rectangular plate of no slideway overlaps the back with one slideway 3, vertical edges is that the rectangular plate 2 of a no slideway is formed, and the base is one and is made up of with rectangular plate 2 a no slideway slideway 3.
Claims (2)
1, the mathematics teaching aid of the multiple shape of a kind of conversion, it is characterized in that: with six block length battens (2), be respectively equipped with bolt hole at every block length batten (2) two ends, and be provided with slideway (3) in the three block length battens (2) therein, be connected convertible multiple shape with bolt (1) with being provided with three of slideway (3) in the six block length battens (2) at interval with three block length battens (2) of no slideway (3).
2, the mathematics teaching aid of the multiple shape of a kind of conversion according to claim 1, it is characterized in that: rectangular plate (2) is to make with wood lath or hard plastic board; Slideway (3) is 1.0～1.5cm with the bolt hole distance.
