Abstract
The utility model relates to a cube expansion teaching aid, comprising six surfaces which form the cube, wherein every two surfaces among the six are provided with a loose-leaf pin joint; and the loose-leaf pin joint is provided with a detachable movable axis. The cube expansion teaching aid can help students better understand the seven edges for shearing the cube, and then the plane expansion graph of the cube can be obtained after shearing. The numbers upon the wood plate can help students understand the position relation of the opposed surfaces and adjacent surfaces of the cube, with simple and direct characteristics.
Description
Technical field
The utility model relates to a kind of square and launches teaching aid.
Background technology
Teaching aid critical role and effect in teaching process are mathematical.For many years, the numerous educators of China have carried out deep exploitation in conjunction with the characteristics of self subject to teaching aid and have utilized widely in teaching practice, and wherein, subjects such as middle school mathematics have reached suitable height to the development and utilization of teaching aid.Now, the modern information technologies fast development, the appearance of new material new process, new round of curriculum reform is all had higher requirement to the exploitation and the mitigation of middle school mathematics teaching aid.In addition, in field research, square launches teaching aid does not have good teaching aid to come adapt teaching on the market, and this exploitation for teaching aid has been created good condition with application.
Summary of the invention
Its purpose of the utility model just is to provide a kind of square to launch teaching aid, can help the student to understand to cut off seven ribs of square, just can obtain the plane outspread drawing of square, the opposite face and the position of adjacent surface in stretch-out view that the student are understood on the square by the numeral on the plank concern.Have characteristics simply and intuitively.
Realize the technical scheme that the utility model adopted, comprise six faces that constitute square, it is hinged to be provided with loose-leaf between per two faces in described six faces, is provided with dismountable movable axis during described loose-leaf is hinged.
Compared with prior art the utlity model has following advantage.
Owing to adopted dismountable structural design, thereby have characteristics simply and intuitively, can help the student to understand to cut off seven ribs of square, just can obtain the plane outspread drawing of square, the opposite face and the position of adjacent surface in stretch-out view that the student are understood on the square by the numeral on the plank concern.
