In mathematical education, solid geometry relevant knowledge more complicated, when not having simulation teaching aid, teacher's explanation is got up more abstract, and student is also difficult to understand simultaneously, so this partial knowledge of students exists very large difficulty.Meanwhile, in solid geometry teaching, space imagination is extremely important, and when running into regular hexahedron relevant knowledge in teaching, the structural representation that can also describe out regular hexahedron on blackboard is explained, but student can not grasp the knowledge of this respect completely.Frustum cone structure is also need learning content, frustum cone structure planimetric map is difficult to the description of image out, this method is for student, need to have certain space imagining ability and logical thinking, at present, still there is certain difficulty in students solid geometry knowledge, and planar graph study of leaning on simple for a long time also can make student be fed up with, lose the interest of study, nor be beneficial to the space imagination of training student.
Therefore be necessary that design one is convenient to teaching, simultaneously the demonstration teaching aid of training student space imagining ability and logical thinking ability can also have become current urgent problem.
Summary of the invention
In order to overcome Problems existing in background technology, the utility model provides a kind of mathematics round platform demonstration teaching aid, utilize three-dimensional circular cylinder model, the structure of round platform can be shown fast to student, student understands to get up also than being easier to simultaneously, the teaching load of teacher can be alleviated, utilize rotatable panel can simulate about round platform relevant nature, be convenient to student understand, avoid teacher to map and delay the class period, utilize space imagining ability and the logical thinking ability of all right training student of teaching mould teaching, the utility model also has reasonable in design, novel unique, advantage easy to use.
For achieving the above object, the utility model is achieved by the following technical solution:
A kind of mathematics round platform demonstration teaching aid, described mathematics round platform demonstration teaching aid comprises bearing 1, end face circle diameter barred body 2, rotation barred body 3, bottom surface circle diameter barred body 4, bottom surface annulus 5, rotating panel 6, fixing spheroid 7, end face annulus 8, hypotenuse barred body 9; Described rotation barred body 3 is connected with bearing 1, the vertical plane of rotating panel 6 is connected with rotation barred body 3, the top of hypotenuse barred body 9 is connected with end face annulus 8 by fixing spheroid 7, the bottom of hypotenuse barred body 9 is connected with bottom surface annulus 5 by fixing spheroid 7, described end face circle diameter barred body 2 is arranged in end face annulus 8, and bottom surface circle diameter barred body 4 is arranged in bottom surface annulus 5.
The height of described rotation barred body 3 is 20-30cm.
Barred body and the annulus of described formation mathematics round platform demonstration teaching aid are made by aluminum alloy materials.
Described bearing 1 has two, is separately positioned on the midpoint of end face circle diameter barred body 2 and bottom surface circle diameter barred body 4.
The top of described rotating panel 6 and bottom respectively with end face circle diameter barred body 2 and bottom surface circle diameter barred body 4 rubbing contact.
The beneficial effects of the utility model:
The utility model provides a kind of mathematics round platform demonstration teaching aid, utilize three-dimensional circular cylinder model, the structure of round platform can be shown fast to student, student understands to get up also than being easier to simultaneously, the teaching load of teacher can be alleviated, utilize rotatable panel can simulate about round platform relevant nature, be convenient to student understand, avoid teacher to map and delay the class period, utilize space imagining ability and the logical thinking ability of all right training student of teaching mould teaching, the utility model also has reasonable in design, novel unique, advantage easy to use.
