Abstract
The utility model discloses a graph demonstrating device for primary mathematics and belongs to teaching tools for the primary mathematics. The graph demonstrating device comprises a plurality of inserting grooves which are transversely and longitudinally formed on a base plate uniformly, inserting handles are arranged in the inserting grooves, and an elastic belt is arranged on the inserting handles; an accommodating box is arranged on lower edge of the base plate; and supporting legs are arranged on the lower part of the accommodating box. The graph demonstrating device is simple in structure and convenient to use, various graphs can be intuitively demonstrated, and students can conveniently understand the graphs and relationships of the graphs. When the graph demonstrating device is used, three inserting handles are taken out of the accommodating box and inserted into three inserting grooves respectively, and the elastic belt is placed on the three inserting handles, so that a triangle is formed. Moreover, by the device, mathematic shapes, such as a parallelogram, a trapezoid and a circle which are taught in the primary mathematics can also be demonstrated.
Description
Technical field:
The utility model belongs to the primary school mathematics teaching aid, particularly primary school mathematics figure demonstrating device.
Background technology:
In primary school math teaching; When lecturing the notion such as similar of shape, figure of various figures and each figure; If directly let students go to read the description of character property; Difficulty relatively then for the pupil so, the student also is difficult in the knowledge that forms system in the brains, and the study of students is brought difficulty.But the pupil is readily appreciated that, accepts the thing of the outwardness seen, therefore has corresponding figure demonstrating device, then seems particularly important.
The utility model content:
The utility model overcomes the weak point of the problems referred to above, and primary school mathematics figure demonstrating device a kind of simple in structure, easy to use is provided; This device is achieved in that and on substrate, evenly is provided with a plurality of slots anyhow that be provided with inserting handle in the slot, inserting handle is provided with elastic cord; On the lower edge of substrate, be provided with holder, be provided with supporting leg below the holder.
The utility model is simple in structure, and is easy to use, can demonstrate various figures intuitively, is convenient to the relation between various figures of students understand and the figure.During use, if form triangle, then elder generation takes out three inserting handles from holder, and inserting handle is inserted respectively in three slots, elastic cord is placed on three inserting handles to get final product again.This device can also be demonstrated the mathematical shape of being learned in parallelogram, trapezoidal, the circular lamp primary school mathematics.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model; 1, substrate 2, slot 3, elastic cord 4, holder 5, supporting leg 6, inserting handle
Embodiment:
1 embodiment is in conjunction with accompanying drawing: primary school mathematics figure demonstrating device is achieved in that and on substrate 1, evenly is provided with a plurality of slots 2 anyhow that be provided with inserting handle 6 in the slot 2, inserting handle 6 is provided with elastic cord 3; On the lower edge of substrate 1, be provided with holder 4, be provided with supporting leg 5 below the holder 4.
The utility model is simple in structure, and is easy to use, can demonstrate various figures intuitively, is convenient to the relation between various figures of students understand and the figure.During use, if form triangle, then elder generation takes out three inserting handles from holder, and inserting handle is inserted respectively in three slots, elastic cord is placed on three inserting handles to get final product again.This device can also be demonstrated the mathematical shape of being learned in parallelogram, trapezoidal, the circular lamp primary school mathematics.
