Abstract

The invention provides a folding ruler which is formed by serially connecting a plurality of ruler bodies through rivets and mainly used for teaching. When the folding ruler is used, the length of the folding ruler can be adjusted according to using needs, and then a teacher can utilize the folding ruler to perform measurement calculation and plotting on the blackboard. Besides, by changing folding modes of the folding ruler, the teacher can make a variety of geometric shapes to perform explanation for students. Therefore, the folding ruler has the advantages of performing calculation and geometric shape transformation, and facilitating improvement on understanding of the students.

Description

technical field [0001] The invention relates to a folding ruler, in particular to a folding ruler for teaching. Background technique [0002] When school teachers give lectures to students, they often use rulers to measure and mark geometric figures on the blackboard. Since the body of an ordinary ruler is only a single straight body, it cannot change with the geometric figures when using it, and students cannot listen to it intuitively. understanding. Contents of the invention [0003] The invention provides a folding ruler, which has the characteristics of measurable calculation and convertible graphics, and can promote students to quickly deepen their understanding. [0004] The invention includes a ruler body of a folding ruler, and the adopted technical solution is that the folding ruler is connected in series by several ruler bodies through rivets. [0005] The beneficial effect of the present invention is that: it is mainly used as a foldable ruler for teaching. W...
