Abstract
The utility model discloses a multifunctional teaching aid for geometry in primary schools. The multifunctional teaching aid is characterized by comprising a bar-shaped piece A, a bar-shaped piece B, a bar-shaped piece C, a bar-shaped piece D, a bar-shaped piece E and a bar-shaped piece F, wherein holes are opened in two ends of each of the six bar-shaped pieces, and the six bar-shaped pieces are movably connected via bolts. The multifunctional teaching aid for geometry in primary schools is improvement of other teaching aids; is beautiful, practical, easy to assemble and produce, and low in cost; and possesses popularization value. In addition, the teaching aid is multifunctional, which can demonstrate a square, a rhombus, a rectangle, a parallelogram, an irregular pentagon, an irregular hexagon, an isosceles trapezoid, a triangle and combination of a triangle and a trapezoid; measure lengths; and demonstrate relationship between the area and the side/height of a geometric figure. When one bolt is removed, the teaching aid can also demonstrate a trapezoid as well as that degree of an angle is related to the angle between two sides instead of length of each side. Preparation of the multifunctional teaching aid is simple, connecting positions can be dismounted at random, and diversification is realized.
Description
Technical field
The utility model relates to a kind of teaching aid, is specifically how much Multifunctional teaching aids of a kind of primary school.
Background technology
As everyone knows, existing market how much teaching aids at primary school is all more single, can not solve with the same teaching aid teaching demonstration problem of multiple figure, if many standby teaching aids will produce more expense.The utility model is the Single-issue that will solve how much teaching aids, realizes the purpose that a tool is multiplex.
The utility model content
This practicality
Novel purpose is to overcome the Single-issue in existing how much teaching aids, and a kind of multi-functional, reliability is high, the life-span is long, simple in structure, with low cost combined appliance for teaching is provided.
The utility model is achieved in thatHow much Multifunctional teaching aids of a kind of primary school is characterized in that: comprise strip bulk A, strip bulk B, strip bulk C, strip bulk D, strip bulk E and strip bulk F, wherein this
The six roots of sensationThe strip bulk
The two ends band porose, and adopt bolt shape to become to be flexibly connected
According to how much Multifunctional teaching aids of a kind of primary school described in the utility model, it is characterized in that:
DescribedStrip bulk A, strip bulk B
Length is 40cm, and is describedStrip bulk C, strip bulk D, strip bulk E and strip bulk F
Long equal 21.5 cm
According to how much Multifunctional teaching aids of a kind of primary school described in the utility model, it is characterized in that: strip bulk A, strip bulk B, strip bulk C, strip bulk D, strip bulk E and strip bulk F
