Problems solved by technology

[0002] In the existing teaching, the teaching ruler is generally used as an instruction tool; while the teaching model is intuitive and easy to enhance students' learning interest, it is an indispensable teaching tool in teaching, but some teaching knowledge is too much for the model of the knowledge to be taught. Simple, there is no corresponding model, if it is difficult to find a suitable tool to replace it at the teaching site, it will bring inconvenience to some teaching and affect the quality of teaching
In the existing teaching rule technology, the teaching rule is used as a teaching model, but there is no teaching rule for teaching knowledge as a teaching model.

Abstract

A multi-shaped teaching ruler comprises a main ruler. One end of the main ruler is provided with a mounting hole which is internally provided with a connecting bolt. The connecting bolt is provided with two sets of sub-rulers symmetrically at two sides of the mounting hole. Each set of sub-rulers comprise at least two rulers. The sets of sub-rulers are hinged. The connecting bolt is provided with fastening nuts at outside sides of the sets of sub-rulers. The multi-shaped teaching ruler has advantages of simple structure and convenient use. A plurality of rulers are hinged and a teaching ruler can be obtained through pulling the plurality of rulers to straight. If the sub-rulers are rotated, a teaching model can be obtained. The teaching model can demonstrate the property and the application of a transversal and parallel lines, and research and application of sum of internal and external angles of a triangle and polygon, so that a teacher can study knowledge in a more clear and visual manner, thereby improving studying interest of the student. Furthermore the multi-shaped teaching ruler facilitates quick model manufacture by a teacher at the teaching field, thereby improving teaching quality and teaching efficiency.

Description

technical field [0001] The invention relates to the field of teaching tools, in particular to a variable teaching rule. Background technique [0002] In the existing teaching, the teaching ruler is generally used as an instruction tool; while the teaching model is intuitive and easy to enhance students' learning interest, it is an indispensable teaching tool in teaching, but some teaching knowledge is too much for the model of the knowledge to be taught. Simple, there is no corresponding model, if it is difficult to find a suitable tool to replace it in the teaching site, it will bring inconvenience to some teaching and affect the quality of teaching. In the existing teaching rule technology, the teaching rule is used as a teaching model, but there is no teaching rule for teaching knowledge as a teaching model. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a variety teaching ruler which is reasonable in design...
