1. permeates the knowledge of plane geometry, which helps children to deepen their understanding of graphics in the process of playing, especially in the division ability of overall graphics, and he will do better than other children. For example, as long as children start to play puzzles and play to a certain extent, as long as they see figures, they will naturally and reasonably divide them, which will be of great help to their later learning of mathematical geometry knowledge. 2. Expand children's imagination. In our eyes, a few simple puzzles may be geometric figures such as trapezoid and triangle. Because children want to use these graphics to create, in their eyes, these graphics have a new meaning. They are also triangles, which will become mountains, roofs, scales on dragons, and even smiling mouths of mothers. Rich imagination can make our children smarter. This kind of imagination is quite effective for the cultivation of thinking ability. 3. Children's aesthetics have been cultivated. How to spell out the graphics is good-looking, only by constantly splicing and comparing can we understand. This process is precisely to cultivate children's aesthetic ability. 4. Parent-child relationship has become more harmonious. For kindergarten children, such activities are helpful to the cultivation of parent-child relationship between parents and children. After all, children are still relatively young, and parents need help when they just start playing puzzles. In the process of helping, apart from solving problems with children, the most important thing for parents is to encourage their children in time, because according to my experience, even parents themselves often find it difficult when they practice to a certain extent. At this time, the potential of children will be much stronger than that of parents. Parents should promptly encourage their children to try more, point out their spelling mistakes, and then let them correct them. At this time, we will find that our children will spell it out again soon. 5. Getting started is easy, and activities are lasting. As parents, we all know that the purpose of letting children participate in various activities is to hope that children can get exercise in activities, but the threshold of many activities is very high. If our children don't have the expertise in this field, they don't even have the chance to try, and the introduction stage of Tangram is quite easy, unlike the instrumental music such as electronic piano and the talent such as painting and calligraphy.
