Abstract
The utility model discloses a multifunctional teaching aid which comprises two rulers, wherein one ends of the two rulers are connected through a rotary shaft; a round protractor of 360 degrees is arranged at the connection part of the two rulers; the circle center of the protractor is positioned on the rotary shaft; and the edge part of the protractor is provided with scales. The two rulers provided by the utility model can be used for measuring and drawing straight lines, and rotate around the rotary shaft so as to form an included angle so as to draw the angle; the protractor can cooperate with the two rulers to draw the angle with specific degrees, and the protractor also can cooperate with the two rulers to intuitively explain a relationship of an interior angle and an exterior angle, thus being convenient for teaching for a teacher.
Description
Technical field
The utility model relates to a kind of middle school mathematics teaching aid, specifically a kind of multi-functional teaching aid.
Background technology
In teaching process; Teaching aid can help the student to understand the knowledge point of being learned intuitively; But at present the teaching aid of relevant mathematical education is considerably less, and present teaching aid exists function singleness, drawback that utilization rate is low, a kind ofly both can in daily teaching, use as instrument if can have; Can assist the teaching aid of students understand knowledge point again, be bound to bring great convenience to teacher's teaching and Students'learning.
The utility model content
The purpose of the utility model is to provide a kind of multi-functional teaching aid, and this teaching aid both can be used as drawing instrument and used, and can assist teacher to impart knowledge to students again.
The technical scheme that its technical problem of the utility model solution is taked is: a kind of multi-functional teaching aid is characterized in that comprise two rulers, two rulers at one end are connected through rotating shaft.
Be provided with 360 ° of protractors of a circle in the junction of said two rulers, the center of circle of said protractor is positioned at said rotating shaft place, and the edge of protractor is provided with scale.
Described protractor is transparent.
The beneficial effect of the utility model is: simple in structure, easy to use, two rulers can be used for measuring and drawing straight line, and two rulers can be drawn angle after rotating around the axis and forming angle; The angle that protractor can cooperate two rulers to draw special angle, protractor cooperates the relation that can also explain interior angle and exterior angle intuitively with two rulers, is convenient to teachers ' teaching.Both can be used as drawing instrument and used, can be used as teaching aid again, improved utilization rate.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 ruler, 2 protractors, 3 rotating shafts.
The specific embodiment
As shown in Figure 1.A kind of multi-functional teaching aid comprises that 1, two ruler 1 of two rulers at one end is connected through rotating shaft 3.
Be provided with 360 ° of protractors 2 of a circle in the junction of said two rulers 1, the center of circle of said protractor 2 is positioned at said rotating shaft 3 places, and the edge of protractor 2 is provided with scale.Being provided with protractor 2 can cooperate the angle of drawing special angle with two rulers 1, and intuitive and convenient more during the concerning of exterior angle in the explanation, is convenient to understand.
Described protractor 2 is transparent.Protractor 2 is made as the transparent observation of students of being convenient to, and intuitive is good.
During use, two rulers 1 can be used for measuring and drawing straight line, and two rulers 1 can be drawn angle behind the 3 rotation formation angles around the shaft; The angle that protractor 2 can cooperate two rulers 1 to draw special angle, protractor 2 cooperates the relation that can also explain interior angle and exterior angle intuitively with two rulers 1, is convenient to teachers ' teaching.
