Oh my God! Since looking at these cubes of the unfolding gifs, the children learn the knowledge of unfolding diagrams and understand them all easily! Spatial thinking is greatly inspired!

The cube is surrounded by six identical squares, and its surface unfold is also composed of six squares. However, its composition has certain rules, and it is not any combination.

There are 11 types of planar unfolding diagrams of cubes (figures with different directions but the same substance after rotation or flipping are not counted repeatedly), which are divided into the following four categories according to their characteristics.

The first category: "1-4-1" type (6 types)

The characteristics are: there are 4 squares in the middle that are connected in a row, and 1 square on each side of the upper and lower sides;

The second category: "1-3-2" type (3 types)

The characteristics are: there are 3 squares in a row in the middle, 2 squares on the upper side (only 1 of which is connected to the middle row), and 1 square on the lower side.

Category 3: "2-2-2" type (1 type)

The characteristics are: the upper, middle and lower squares are connected into a row, and there is only one connection between each row;

Category 4: "3-3" type (1 type)

The characteristics are: 3 squares in a row on the top and bottom, and only one square is connected between them;

Today, the teacher shares the cube unfolding chart information for everyone, and collects it carefully for the child in need until he understands and learns, and believes that it will be of great help to the improvement of grades. #Education # #教育听我说 #
