The utility model discloses a multifunctional mathematics teaching aid which comprises a ruler. One side of the ruler is graduated, and an elongated hole shorter than the ruler is arranged at a position, close to the other side, on the ruler. A protractor and a compasses device are connected into the elongated hole. The multifunctional mathematics teaching aid is simple in structure, reasonable in design, convenient to carry and easy to use and integrates various functions, and burdens can be relieved for teachers while teaching efficiency can be effectively improved.
Description
Technical field
The utility model relates to a kind of mathematical education apparatus, is to relate in particular to a kind of multifunctional mathmatical teaching aid.
Background technology
At present, in the mathematical education process, the teacher often need use many teaching aids; As need use ruler when drawing straight line, and draw bowlder and need use compasses, need use protractor when taking measurement of an angle; When drawing the angle of certain angle, need use protractor and ruler or the like simultaneously.These teaching aids generally disperse to place, and multiple apparatus on math teacher need be with when giving lessons not only carries inconvenience, and in a rush sometimes in giving lessons, and influences efficiency of teaching easily.
The utility model content
The problem that the utility model will solve provides a kind of simple in structure, and is reasonable in design, is convenient for carrying, and is easy to use, and integrates functions as one, and can alleviate teacher's burden, can effectively improve the multifunctional mathmatical teaching aid of efficiency of teaching again.
In order to address the above problem, the utility model adopts following technical scheme:
A kind of multifunctional mathmatical teaching aid comprises ruler, is provided with scale in a side of ruler, and the position near opposite side on the said ruler is provided with the slotted hole of a length less than ruler length, in slotted hole, is connected with protractor and compasses device.
Below be the further improvement of the utility model to such scheme:
The center of said protractor is provided with second rotating shaft, and said second rotating shaft is positioned at slotted hole and flexibly connects with slotted hole.
Further improve: compasses device comprises the first compasses supporting leg and the second compasses supporting leg; The wherein end of the first a compasses supporting leg and wherein end of the second compasses supporting leg is overlapping and be rotationally connected through first rotating shaft, said first rotating shaft is positioned at slotted hole and flexibly connects with slotted hole.
Further improve: the said first compasses supporting leg is connected with chalk sleeve away from an end of first rotating shaft, and chalk is installed in chalk sleeve, and the said second compasses supporting leg is provided with needle tip away from an end of first rotating shaft.
When needs picture bowlder; Can the needle tip of the first compasses supporting leg be fixed on the blackboard; The second compasses supporting leg and the first compasses supporting leg are separated certain distance, make the second compasses supporting leg rotate, make the draw circle of required radius of chalk on the second compasses supporting leg around the first compasses supporting leg.
The utility model is simple in structure, and is reasonable in design, is convenient for carrying, and is easy to use, and integrates functions as one, and can alleviate teacher's burden, can effectively improve efficiency of teaching again.
