Abstract
The utility model discloses a multifunctional mathematic teaching aid in order to achieve multiple purposes. The multifunctional mathematic teaching aid is characterized in that scales are arranged on one side of a ruler, and teaching aid models identical with a right triangle, an isosceles triangle, a parallelogram, an isosceles trapezoid and a circle are arranged on the other side of the ruler, more particularly, the teaching aid models of the right triangle, the isosceles triangle, the parallelogram, the isosceles trapezoid and the circle are embedded on the ruler, and each teaching aid model can be used independently; and a calculator is fixed on the ruler. Accordingly, the multifunctional mathematic teaching aid is capable of directly carrying out the construction by using the ready-made shapes and carrying out the mathematical calculation by using the calculator; and the multifunctional mathematic teaching aid of the utility model has the advantages of simple structure, reasonable design and convenient use.
Description
Technical field
The utility model relates to the articles for education and teaching technical field, specifically a kind of multifunctional mathmatical teaching aid.
Background technology
At present, the teaching aid of teachers and students' usefulness is very many, and the student will be with a large amount of mathematics teaching aids when last mathematics class, and students' union leaves behind indivedual teaching aids and can't map sometimes, can give like this teachers and students bring many not time; And the student who much begins to learn is very abstract to geometric figure, easily obscures; Run into and look for counter when calculating again.Can waste a lot of times like this, need to improve.
Summary of the invention
The purpose of this utility model be with overcome above-mentioned deficiency, a kind of multifunctional mathmatical teaching aid is provided.
The technical scheme that its technical solution problem of the utility model is adopted is: a side of ruler is provided with scale, opposite side is provided with and right-angle triangle, isosceles triangle, parallelogram, isosceles trapezoid, circular corresponding to teaching aid model, and counter is fixedly mounted on the ruler.
Described right-angle triangle, isosceles triangle, parallelogram, isosceles trapezoid, circle are the teaching aid models that is embedded on the ruler, and each model can independently use.
Compared with prior art it is simple in structure, reasonable in design, elegant in appearance, easy to use for the utility model, makes the best use of everything.
Description of drawings
Accompanying drawing 1 is the structural representation of a kind of multifunctional mathmatical teaching aid of the utility model.
Specific embodiment
With reference to Figure of description a kind of multifunctional mathmatical teaching aid of the present utility model is done and to be specified.
A kind of its structure of multifunctional mathmatical teaching aid of the present utility model is by ruler 1, right-angle triangle 2, isosceles triangle 3, parallelogram 4, isosceles trapezoid 5, circular 6 and counter 7 form.Right-angle triangle 2, isosceles triangle 3, parallelogram 4, isosceles trapezoid 5, circular 6 are embedded in a side of ruler 1, counter 7 is fixedly mounted on the ruler 1, just use a side ruler 1 of band scale when needing with the picture straight line, when drawing the isosceles triangle figures, can directly utilize on the ruler 1 with ready-made teaching aid model, usefulness makes illustrations when especially doing exercise at middle school student, so both can use these several figures simultaneously, can compare discriminating to these several figures again, can also utilize counter 7 to carry out mathematical computations.Use easily, fast.
A kind of its processing and fabricating of multifunctional mathmatical teaching aid of the present utility model is very simple, and the processing of by specification accompanying drawing gets final product.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
Claims (2)
1. multifunctional mathmatical teaching aid, comprise the ruler body, it is characterized in that: a side of ruler is provided with scale, and opposite side is provided with and right-angle triangle, isosceles triangle, parallelogram, isosceles trapezoid, circular corresponding to teaching aid model, and counter is fixedly mounted on the ruler.
2. a kind of multifunctional mathmatical teaching aid according to claim 1 is characterized in that: described right-angle triangle, isosceles triangle, parallelogram, isosceles trapezoid, circle are the teaching aid models that is embedded on the ruler, and each model can independently use.
