CN202003545U - Four-piece puzzle block - Google Patents

Abstract

The utility model relates to teaching aids or toys, in particular to a four-piece puzzle block, which consists of four puzzle pieces. The first puzzle piece is a cube, two cubes are combined together in a face-to-face contacting manner to form the second puzzle piece, three cubes are combined together in a face-to-face contacting manner to form each of the third puzzle piece and the fourth puzzle piece, and the third puzzle piece and the fourth puzzle piece are two unique combinations different from each other. Each base unit includes the four puzzle pieces, one base unit forms a 3*3 cube, two base units can be assembled to form a 2*3*3 cuboid, and three base units can be assembled to form a 3*3*3 cube. The four-piece puzzle block is simple in structure and easy to implement, meets requirements of people at different ages, is a combination of a teaching aid and a toy, integrates plane geometry with three-dimensional space, can be used for training spatial image thinking of people, and stimulates potential independent innovation capability of people.

Description

Four become piece

Technical field

The utility model relates to education and instruction apparatus or toy, and particularly a kind of four become piece, when teaching solid geometry, can make the teacher make the student use institute at many a kind of effective instruments extracurriliar and gain knowledge, and use one's hands and brains.By cultivating student's space thinking in images, come developing right brain, excite the potential capability of independent innovation of people.

Background technology

Purposes is more single in the present building blocks piece series products, knowledge and technology content are higher and to be fit to great majority adults' like products again less, the study of holding concurrently is less in the teaching aid or the toy of one with amusement, raising along with present people's living standard, need on higher knowledge aspect, carry out amusement, for adapting to this variation, four become piece can address this problem.

Summary of the invention

In order to solve the apparatus problem that people use one's hands and brains, the utility model provides a kind of four to become piece, integrate plane geometry and space multistory knowledge and change various, can make people by using one's hands and brains, culture space thinking in images, exploitation people's right brain makes left and right sides brain balanced growth, thereby improves whole intellectual level.

The scheme that the utility model adopted is:

Four become piece is made up of four pieces, described four pieces obtain like this: first piece is a square, second piece is that two described squares are combined formation face-to-face contiguously, the 3rd piece is three described squares to be combined face-to-face contiguously be formed with and only two kinds of different combinations with the 4th piece, and described four pieces are base units of described four change pieces.Can be combined into 3 * 3 squares with a described base unit, can be combined into 2 * 9 rectangles or 3 * 6 rectangles or 2 * 3 * 3 rectangular parallelepipeds with two described base units, can be combined into 3 * 9 rectangles or 3 * 3 * 3 cubes with three described base units, can also risk bigger rectangle of area and the bigger solid of volume with how described base unit, the position difference of piece can form multiple different spelling.When learning the plane symmetry figure, can optionally choose different pieces and carry out picture mosaic for the students of the junior years.

The beneficial effects of the utility model are:

Four become the simple realization easily of tile configuration, adapt to each age group people's needs, and teaching aid combines with toy, integrate plane geometry and space multistory, develop right brain in the time of training people's space thinking in images, impelled people to use one's hands and brains, excited the potential capability of independent innovation of people.

Description of drawings

Further specify below in conjunction with figure of the present utility model:

Fig. 1 to Fig. 4 is the planimetric map of described four pieces;

Fig. 5 is an example of a kind of combination of 3 * 3 rectangles;

Fig. 6 is an example of a kind of spelling of 2 * 3 * 3 rectangular parallelepipeds;

Fig. 7 is an example of 3 * 3 * 3 cubical a kind of spellings;

Fig. 8 is the plane symmetry graphical examples;

Fig. 9 is the plane symmetry graphical examples;

Figure 10 is the plane symmetry graphical examples.

Among the figure, No. 1.1 pieces, No. 2.2 pieces, No. 3.3 pieces, No. 4.4 pieces.

Embodiment

The planimetric map of four pieces as described in as Fig. 1 to Fig. 4 being, four become piece is made up of four pieces, first piece (1) is a square, second piece (2) is that two described squares are combined formation face-to-face contiguously, the 3rd piece (3) is three described squares to be combined face-to-face contiguously be formed with and only two kinds of different combinations with the 4th piece (4), and described four pieces are base units of described four change pieces.As Fig. 5 is an example that is combined into a kind of combination of 3 * 3 rectangles with base unit as described in; As Fig. 6 is an example that is combined into a kind of spelling of 2 * 3 * 3 rectangular parallelepipeds with base unit as described in two; As Fig. 7 is an example that is combined into a kind of spelling of 3 * 3 * 3 rectangular parallelepipeds with base unit as described in three; As Fig. 8 to Figure 10 is the symmetric figure example that the students of the junior years are combined into when learning the plane symmetry figure.Can also risk bigger rectangle of area and the bigger solid of volume with how described base unit, the position difference of piece can form multiple different spelling.

Claims (1)

1. one kind four becomes piece, form by four pieces, it is characterized in that: described four pieces obtain like this: first piece (1) is a square, second piece (2) is that two described squares are combined formation face-to-face contiguously, and the 3rd piece (3) is three described squares to be combined face-to-face contiguously be formed with and only two kinds of different combinations with the 4th piece (4).
