Abstract
The utility model provides a kind of model teaching aid imparted knowledge to students for parallel lines property, is made up of first straight panel, Article 2 straight panel, Article 3 straight panel and screw.First straight panel, Article 2 straight panel is equidistant and is placed in parallel, and first straight panel of Article 3 straight panel oblique and Article 2 straight panel, Article 3 straight panel are consolidated with first straight panel and Article 2 straight panel contact point with screw.The utility model is simple in construction, simple for production, cheap, is conducive to whole teaching process efficient quick, optimizes teaching environment, improves classroom teaching efficiency.
Description
Technical field
The utility model belongs to a kind of instrument of several teaching, specifically a kind of model imparted knowledge to students for parallel lines property
Teaching aid.
Background technology
Geometry is exploitation students' learning ability, the cornerstone of Developing Students ' thinking ability.In teaching, graphic language is often
Than word language image much, vividly much, to be readily appreciated that during student's cognitive concept with reference to figure, student can be given full play to
The enthusiasm of study, largely optimizes classroom instruction.And traditional teaching method, student can only intuitively look at the blackboard
On picture or multimedia video photo, understand two straight lines by Article 3 straight line cut produce corresponding angles, alternate interior angle, with side
The relation of interior angle, student has just contacted such geometrical issues, very abstract.If graphical visualization, material objectization can be made by making
Teaching aid is imparted knowledge to students, and the knowledge point of " properties of parallel lines " is understood and grasped with regard to that can deepen students ' understanding.Although traditional teaching way side
Just, but this traditional teaching efficiency is perfect not enough, be mainly manifested in：Teaching can only intuitively look at the blackboard on picture or
Multimedia video photo, uninteresting, shortage interest is unfavorable for students ' understanding and understands and grasp knowledge point.
The content of the invention
For weak point in the property teaching process of existing traditional parallel lines, the purpose of this utility model is to provide
A kind of model teaching aid imparted knowledge to students for parallel lines property.
The purpose of this utility model can be realized by following measures：
A kind of model teaching aid imparted knowledge to students for parallel lines property, is by first straight panel, Article 2 straight panel, Article 3 straight panel
Constituted with screw.First straight panel, Article 2 straight panel is equidistant and is placed in parallel, Article 3 straight panel oblique in first straight panel and
In Article 2 straight panel, Article 3 straight panel is consolidated with first straight panel and Article 2 straight panel contact point with screw.
Advantage of the present utility model and the beneficial effect produced are：
1st, the utility model is fixed on the junction that two vertical bars are cut by the 3rd vertical bar by two screws, thus can be with
Composition one is used for the model teaching aid that parallel lines property is imparted knowledge to students, and allows student to take the property of parallel lines in kind cognitive, probe into corresponding angles,
Alternate interior angle, the respective relation in internal angles on the same side, model teaching aid provide convenient for teachers ' teaching, optimize teaching environment, so that raising class
Hall efficiency of teaching.
3rd, the utility model is simple in construction, simple for production, and cost is low, safe and reliable, explanation《The property of parallel lines》" three
It is simple and convenient during relation between line anise ".As special purpose model teaching aid during several teaching, configure in class, be several teaching
Play beneficial effect.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the accompanying drawings, then to the utility model it is described in further detail：
As shown in figure 1, a kind of model teaching aid imparted knowledge to students for parallel lines property, is by first straight panel 1, Article 2 straight panel
2nd, Article 3 straight panel 3 and screw 4 are constituted.First straight panel 1, Article 2 straight panel 2 is equidistant and is placed in parallel, Article 3 straight panel 3
In first straight panel 1 of oblique and Article 2 straight panel 2, Article 3 straight panel 3 and first straight panel 1, the contact point spiral shell of Article 2 straight panel 2
Nail 4 is consolidated.It so can be formed by two straight lines and teaching mode cut by Article 3 straight line.
Explained in teacher《The property of parallel lines》, two straight lines are cut the corresponding angles produced by Article 3 straight line, interior
Alternate angle, internal angles on the same side, i.e. " three lines are anistree ".When, can first it be observed by student, then rely on student to do it yourself to operate, probe into
Corresponding angles, alternate interior angle, the respective relation in internal angles on the same side, deepen student to " three lines are anistree " the cognition and comprehension, firmly grasp " parallel lines
Property " this knowledge point.The geometric knowledge formation space of acquisition, by object visual assembling process, increase student
Learning interest, enrich the imagination of student, be conducive to pair《The property of parallel lines》Understanding, be easy to teaching, optimize teaching environment,
Improve classroom teaching efficiency.
