Wu En (German: Spiegel Gabe; English: The Froebel Gift is a set of educational materials designed by Friedrich Froebel, the originator of modern preschool education. They were first used in the world's earliest kindergartens in Bud Blanckenburg. Froebel emphasized the importance of free play in childhood. Every kind of gift is a material designed by God for children's independent activities. 1844, in a letter to Frobel, Autili de Liagrey said that he observed that playing with kindness made children lively and free, but people's understanding of it was simplified to a mechanical way. "It is necessary to realize how this goodwill was eventually abused by kindergarten teachers who followed Frobel. It is very important to understand the educational goals that Froebel expects kindness to achieve: first, kindness is used by children to learn and use the environment; Secondly, they point out to the children the connection between human life and nature; Finally, they have established a bond with adults and children who play kindly "-Joachim Liebschner. Today, kindness is still widely used in early education in Korea and Japan. The first gift is six wool balls of different colors (red, green, blue, yellow, purple and orange). Each ball is tied with a thread, and the color of the thread is the same as that of the ball. Before or after the child speaks, the mother guides the child to observe and grasp these soft balls, making him familiar with their shape, color and dynamic and static state, and developing the child's color discrimination ability. With the development of children's perception and thinking language, mothers shake the ball around, saying back and forth, up and down, left and right, and develop children's spatial concept. You can also put the ball in your palm to indicate "yes", and then suck it up, leaving your palm empty to indicate "no", thus developing children's concepts of affirmation and negation. Froebel conceived 50 kinds of playing methods with six balls in observation and experiment, and systematically trained children's various abilities. The second kind of gifts are wooden spheres, cubes and cylinders. Their height and diameter are one and a half inches. The latter two are perforated and connected with wooden sticks as threads. The ball represents motion, the cube represents stillness, and the cylinder has both motion and stillness. Through this kind of "gift", children can know the shapes, attributes and relationships of objects, and they can also be used to make small tables, stools, stoves and other items. Develop children's creative imagination through various ways of playing and combining. The first and second kinds of gifts are for children before the age of 3, and the following kinds of gifts are for children aged 3-7. The third gift is a wooden cube (building block). It can be divided into eight small cubes and combined into a regular big cube. This kind of "gift" can let children know the various shapes and properties of objects and understand the relationship between parts and the whole and its concepts. Through the stacking of various shapes, children can also exercise their creative combination ability, modeling, architectural art and symbolic association ability. The fourth gift is a wooden cube, which can be divided into eight small cuboids. Eight rectangular squares are 5 cm long, 2.5 cm wide and 1.25 cm thick. Together, they are a 5 cm cube. Children can get the concepts of length, width and thickness by comparing cuboids in the game. The fifth gift is a wooden cube, which can be divided into 27 equal cubes. Among them, three cubes are divided into six triangles. There are three small cubes divided into four parts, forming 12 triangles. The sixth gift is a wooden cube, which can be divided into 27 small cuboids. Some of them can also be divided into smaller parts such as boards, oblique angles, etc. Through the fifth and sixth kinds of building block games, children are provided with geometric figures of various shapes, laying the foundation for their future study of geometry and mathematics.
