Abstract

The utility model discloses a teaching aid is demonstrated to square for teaching, its characterized in that shows to cover respectively have the fold plane at six off -plates of square box body, the size of fold plane equals with the one side of square box body, can realize between the fold plane folding six faces of square box body with the middle part of fold plane is equipped with the magnet piece respectively, magnet piece on six faces of square box body with magnet piece on the fold plane is corresponding. Through above setting, the teacher need not to map on the blackboard when explanation solid geometry knowledge, the utility model discloses but the structure of ocular demonstration cube is formed, and it is directly perceived to impart knowledge to students, and the student of being convenient for understands the grasp.

Description

Square demonstration teaching aid is used in teaching

Technical field

The utility model relates to a kind of teaching aid, is a kind of teaching square demonstration teaching aid specifically.

Background technology

Teacher, when explaining solid geometry knowledge, can only explain by map on blackboard, and the structure cannot demonstrating square forms, and student can not planform intuitively after cube expansion, is not easy to the knowledge of student's understand and master solid figure.

Summary of the invention

The purpose of this utility model provides a kind of structure simple, the convenient square demonstration teaching aid intuitively of teaching demonstration.

To achieve these goals, the utility model is covered with fold plane respectively in six appearances of square box body, the size of described fold plane is equal with the one side of square box body, can realize between described fold plane folding, be respectively equipped with flat thin magnet in six faces of described square box body and the middle part of described fold plane, the flat thin magnet on six faces of described square box body is corresponding with the flat thin magnet on described fold plane.

By above setting, teacher is when explaining solid geometry knowledge, and without the need to mapping on blackboard, the utility model can the cubical structure of ocular demonstration form, and teaching is directly perceived, is convenient to student's understand and master.

Accompanying drawing explanation

Now by reference to the accompanying drawings the utility model is described further.

Fig. 1 is structural representation of the present utility model.

In figure: 1, square box body, 2, fold plane, 3, flat thin magnet.

Embodiment

As shown in Figure 1, the utility model is covered with fold plane 2 respectively in six appearances of square box body 1, the size of described fold plane 2 is equal with the one side of square box body 1, can realize folding between described fold plane 2, be respectively equipped with flat thin magnet 3 in six faces of described square box body 1 and the middle part of described fold plane 2, the flat thin magnet 3 on six faces of described square box body 1 is corresponding with the flat thin magnet 3 on described fold plane 2.By above setting, fold plane 2 of the present utility model is adsorbed on the outside surface of square box body 1 by flat thin magnet 3, and fold plane 2 forms a complete cube.When unfolded face 2, can the cubical structure composition of ocular demonstration.

Claims (1)

1. square demonstration teaching aid is used in teaching, it is characterized in that: be covered with fold plane respectively in six appearances of square box body, the size of described fold plane is equal with the one side of square box body, can realize between described fold plane folding, be respectively equipped with flat thin magnet in six faces of described square box body and the middle part of described fold plane, the flat thin magnet on six faces of described square box body is corresponding with the flat thin magnet on described fold plane.
