Abstract
The utility model discloses a kind of Novel mathematical teaching aid, it relates to realia technical field, the two ends that connect chi are provided with connection pin, connecting chi is connected with upper main scale and lower main scale respectively by connecting pin, the both sides that connect chi are respectively arranged with protractor and set square, on upper main scale and lower main scale, are all connected with auxiliary scale by the second rotating shaft.It can overcome the drawback of prior art, reasonable in design novelty, ruler, set square, protractor are set to one, use more convenient, and be provided with multiple circular salient points, therefore can apply the various polygons of the dynamic demonstration of rubber band, the student's of raising learning interest, has also improved student's learning efficiency simultaneously.
Description
Technical field:
The utility model relates to a kind of Novel mathematical teaching aid, belongs to realia technical field.
Background technology:
At present, teacher is in mathematical education process, often use teaching aid to map on blackboard, especially in geometric construction presentation process, can use ruler, compasses, protractor teaching aid etc., these teaching aids relatively disperse, and when mapping, need change back and forth, waste valuable instructional blocks of time, and greatly increased teacher's workload.
And in middle school teaching, when secondary school teachers is imparted knowledge to students polygonal content on classroom, substantially without teaching aid assistant analysis, all directly on blackboard, to draw and analyze, the content of courses is more inflexible, be unfavorable for cultivating student and observe the geometric essence of understanding by the angle of motion change, therefore can not improve student's learning initiative.
Utility model content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of Novel mathematical teaching aid.
Novel mathematical teaching aid of the present utility model, it comprises main scale, lower main scale, connects chi, connects pin, protractor, secondary chi, the first rotating shaft, bush of chalk, set square, circular salient point, auxiliary scale and the second rotating shaft, the two ends that connect chi are provided with connection pin, connecting chi is connected with upper main scale and lower main scale respectively by connecting pin, the both sides that connect chi are respectively arranged with protractor and set square, on upper main scale and lower main scale, are all connected with auxiliary scale by the second rotating shaft.
As preferably, the middle part of described connection chi is provided with the first rotating shaft, and the first rotating shaft is connected with one end of secondary chi, and the other end of secondary chi is provided with bush of chalk, chalk is fixed on to the front end of bush of chalk, can help to draw circular arc or circle.
As preferably, on described upper main scale, lower main scale, auxiliary scale and set square, be provided with circular salient point, in use, can be equipped with rubber band, rubber band can form triangle, square, rectangle and other polygon on described circular salient point stretches arbitrarily, can make like this student increase learning interest in the process of study, improve learning efficiency.
The beneficial effects of the utility model: it can overcome the drawback of prior art, reasonable in design novelty, ruler, set square, protractor are set to one, use more convenient, and be provided with multiple circular salient points, therefore can apply the various polygons of the dynamic demonstration of rubber band, the student's of raising learning interest, has also improved student's learning efficiency simultaneously.
Brief description of the drawings:
For ease of explanation, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is the utility model structural representation;
Fig. 2 is for using rubber band to be drawn into leg-of-mutton structural representation on the utility model;
Fig. 3 is for using rubber band to be drawn into foursquare structural representation on the utility model.
The upper main scale of 1-; Main scale under 2-; 3-connects chi; 4-connects pin; 5-protractor; The secondary chi of 6-; 7-the first rotating shaft; 8-bush of chalk; 9-set square; The circular salient point of 10-; 11-auxiliary scale; 12-the second rotating shaft.
Detailed description of the invention:
As Figure 1-3, this detailed description of the invention is by the following technical solutions: it comprises main scale 1, lower main scale 2, connects chi 3, connects pin 4, protractor 5, secondary chi 6, the first rotating shaft 7, bush of chalk 8, set square 9, circular salient point 10, auxiliary scale 11 and the second rotating shaft 12, the two ends that connect chi 3 are provided with and connect pin 4, connecting chi 3 is connected with upper main scale 1 and lower main scale 2 respectively by connecting pin 4, the both sides that connect chi 3 are respectively arranged with protractor 5 and set square 9, on upper main scale 1 and lower main scale 2, are all connected with auxiliary scale 11 by the second rotating shaft 12.
Wherein, the middle part of described connection chi 3 is provided with the first rotating shaft 7, the first rotating shafts 7 and is connected with one end of secondary chi 6, and the other end of secondary chi 6 is provided with bush of chalk 8, chalk is fixed on to the front end of bush of chalk 8, can help to draw circular arc or circle; On described upper main scale 1, lower main scale 2, auxiliary scale 11 and set square 9, be provided with circular salient point 10, in use, can be equipped with rubber band 13, rubber band 13 can form triangle on described circular salient point 10 stretches arbitrarily, square, rectangle and other polygon, can make student increase learning interest like this in the process of study, improves learning efficiency.
More than show and described general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
