Abstract
The utility model discloses a primary school math ruler, which belongs to stationery and aims to provide a ruler with diversified functions. The ruler comprises a straight edge. One side of the straight edge is provided with an isosceles right-angled triangle plate, and the other side is provided with a right-angle triangle plate with one angle being 30 DEG. Different geometric patterns are disposed on the surface of the straight edge. The utility model is advantageous in that the structure is simple; the straight edge can be used for measuring and drawing straight lines; the triangle plate can be used for drawing triangles in different sizes; the geometric patterns on the surface of the straight edge can be used for students to draw different geometric patterns; the carrying is convenient.
Description
Technical field
The utility model relates to the stationery that a kind of pupil uses, a kind of specifically Arithemetic ruler for primary school.
Background technology
In the primary school mathematics learning process, the ruler learning tool that is absolutely necessary, the most frequently used ruler kind has ruler and set square.At present, ruler and set square on the market are of a great variety, but most of function singleness, when buying, the student need buy several rulers such as ruler and set square simultaneously, the ruler of this function singleness not only carries inconvenience, and buys several more money of cost that need simultaneously, increases student's financial burden.
The utility model content
In order to overcome the deficiency that above-mentioned prior art exists, a kind of primary school student chi of providing a kind of ruler and set square to be connected as a single entity is provided the purpose of this utility model, can draw different angles to solve ruler when measuring length.
The technical scheme in the invention for solving the technical problem is: a kind of primary school student chi, comprise ruler, side at ruler is provided with the isosceles right angle triangle, and opposite side is provided with the right angle triangle at 30 ° of angles, is provided with different geometrical patterns on the ruler surface.
Described geometrical pattern comprises circle, ellipse, pentagon, hexagon and five-pointed star pattern, and described geometrical pattern also can be other different geometrical patterns.
The beneficial effects of the utility model are: this Arithemetic ruler for primary school is simple in structure, ruler can be used for measuring and the picture straight line, set square can be used for the different triangles of picture, and the geometrical pattern on ruler surface can be drawn different geometrical patterns in the time after school for the student, increases student's study enjoyment.This Arithemetic ruler for primary school has advantage easy to carry simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Description of reference numerals: 1 ruler, 230 ° of angle right angle triangles, 3, the isosceles right angle triangle.
The specific embodiment
As shown in Figure 1, this kind Arithemetic ruler for primary school comprises ruler 1, is provided with isosceles right angle triangle 3 in a side of ruler, and opposite side is provided with the right angle triangle 2 at 30 ° of angles.Ruler 1 can be used for measuring and draw straight line, and set square can be used for the different triangles of picture.On ruler 1 surface, be provided with different geometrical patterns, comprise circle, ellipse, pentagon, hexagon and five-pointed star pattern, described geometrical pattern also can be other different geometrical patterns, and the student can utilize this to draw different geometrical patterns in the time after school, increases student's study enjoyment.
Whole Arithemetic ruler for primary school can form by integral molded plastic.
