Abstract

The invention discloses a learning mold of a side surface unfolding pattern of a cube and a 90-degree rotation operation method thereof, and relates to a learning mold and an operation method thereof.In the learning stage of the junior middle school, there are various patterns after the cube is unfolded, the patterns need to be mechanically memorized by students one by one, it is difficult to thestudents to distinguish whether an unfolded pattern formed by six panels is a side surface unfolding pattern of the cube or not. In the invention, a first constitution panel, a second constitution panel, a third constitution panel and a fourth constitution panel form a square frame in an enclosing manner, a fifth constitution panel is arranged at the top end of the square frame, a sixth constitution panel is arranged at the bottom end of the square frame, and the six constitution panels are connected in a detachable manner. According to the method, one, two, three or four constitution panelsare selected from the unfolded pattern formed by the six constitution panels to serve as an overall rotation structure, and the left constitution panels serve as a fixed structure; whether there is anincluded angle of 90 degrees between the overall rotation structure and the fixed structure or not is judged, and if so, the overall rotation structure rotates by 90 degrees. The learning mold is used for assisting teaching or learning.

Description

technical field [0001] The invention relates to a learning mold and an operation method thereof, belonging to the technical field of teaching. Background technique [0002] At present, for the junior high school stage, there is relevant knowledge about the unfolded figures on the side of the cube. The existing teaching methods often list all the unfolded figures one by one, so that students can memorize them by rote, and some use formulas, so that not only must they memorize the formulas, You also need to understand the formulas, and you have to apply the formulas when using them. It is very inflexible to use, not only time-consuming but also brain-intensive, and it is easy to make mistakes. Contents of the invention [0003] The object of the present invention is to provide a learning mold for developing graphics on the side of a cube and its 90° rotation operation method to solve the problem that in the junior high school learning stage, due to the variety of graphics af...
