Abstract
The utility model relates to a mathematic teaching aid, which comprises a main body and a base. The central position on the main body bottom side is provided with a base installation hole for inserting the base. The left side of the main body central part is provided with a transparent left groove. The right side of the main body central part is provided with a transparent right groove corresponding to the transparent left groove. The lower part of the main body is provided with two guide rails and a sliding block capable of moving along the guide rails. The teaching aid has a simple structure and is convenient to use. The transparent left groove and the transparent right groove are used for placing teaching cards prepared by a teacher before a class is started. The guide rails and the sliding block can be used for dynamically demonstrating some application problems related to walking distances. Teaching practices are saved. The teaching labor intensity is further alleviated. Meanwhile, the learning interest of students is enhanced. Labor-saving and time-saving effects are achieved. The base is detachable and has an adjustable height. Therefore, the teaching aid portability is made possible.
Description
Technical field
The utility model relates to a kind of teaching aid, particularly a kind of mathematics teaching aid.
Background technology
Current mathematics is given lessons, and the method for add, subtract, the calculating of multiplication and division being drawn squares, write, giving an oral account by the teacher on blackboard is taught; The application topic of some travel distances also mostly adopts line explanation on blackboard; So not only waste instructional blocks of time, labour intensity is large, and interest is not strong, and the pupil is difficult for accepting; Although have some teaching aids in prior art, be not easy to carry because volume is large also and can not get widespread use.
Therefore, can design a kind of teaching aid to overcome above-mentioned defect, for those skilled in the art have opened up brand-new thinking.
Summary of the invention
The utility model aims to provide a kind of mathematics teaching aid, solves in the mathematical education process and wastes instructional blocks of time, and labour intensity is large, and interest is not strong, and the pupil is difficult for accepting and not portable problem.
The purpose of this utility model is achieved in that this mathematics teaching aid comprises main body and base, be provided with the base installing hole inserted for base in centre position, main body bottom side, the left side, middle part of main body is provided with transparent left groove, and on the right side, middle part of main body, corresponding transparent left groove is provided with transparent right groove; The bottom of main body is provided with two guide rails and energy sliding shoe along guide rail movement.
Preferably, base comprises base insertion end, base inner prop, base column jacket, chassis and register pin, and the base insertion end is positioned at base inner prop top, base inner prop inserted base column jacket, and the base column jacket comprises some pilot holes for inserting register pin.
Preferably, also be provided with scale on the bottom margin of main body.
The beneficial effects of the utility model: simple in structure, easy to use, transparent left groove and transparent right groove are for placing the teaching card of preparing before class-teaching of teacher; Guide rail and sliding shoe can be inscribed in some application about travel distance of dynamic demonstration, have so not only saved teaching practice but also have alleviated the labour intensity of teaching, have also increased student's learning interest simultaneously, have realized time saving and energy saving effect; And detachably can highly regulating of base makes the portable possibility that becomes of teaching aid.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of base 2.
In figure: 1 is main body, and 2 is base, and 3 is transparent left groove, and 4 is transparent right groove, and 5 is guide rail, and 6 is sliding shoe, and 7 is the base insertion end, and 8 is the base inner prop, and 9 is the base column jacket, and 10 is chassis, and 11 is register pin, and 12 is pilot hole.
Embodiment
Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, this mathematics teaching aid comprises main body 1 and base 2, be provided with the base installing hole inserted for base 2 in main body 1 centre position, bottom side, the left side, middle part of described main body 1 is provided with transparent left groove 3, and on the right side, middle part of described main body 1, corresponding described transparent left groove 3 is provided with transparent right groove 4; The bottom of described main body 1 is provided with two guide rails 5 and energy sliding shoe 6 along guide rail movement.
For example also be provided with scale on the bottom margin of described main body 1.
Base 2 for example comprises base insertion end 7, base inner prop 8, base column jacket 9, chassis 10 and register pin 11, base insertion end 7 is positioned at base inner prop 8 tops, base inner prop 8 inserted base column jackets 9, base column jacket 9 comprises that some pilot hole 12(for inserting register pin 11 are as shown in Figure 2).
Because this teaching aid is less lighter, can carries back and forth class hour so teacher is upper, or be placed on the drawer the inside in classroom.During use, the height of the height adjusting base 2 first needed according to teaching aid is extracted certain-length by base inner prop 8 from base column jacket 9, then inserts pilot hole 12 with register pin 11 and highly fix, then by the base installing hole of insertion end 7 inserted bases 2; Transparent left groove 3 and transparent right groove 4 are for placing the teaching card of preparing before class-teaching of teacher; Guide rail 5 and sliding shoe 6 can be inscribed in some application about travel distance of dynamic demonstration, have so not only saved teaching practice but also have alleviated the labour intensity of teaching, have also increased student's learning interest simultaneously, have realized time saving and energy saving, portable effect.
The above is illustrated the utility model with way of example, but the utility model is not limited to above-mentioned specific embodiment, and all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
