A complete picture of a jigsaw puzzle. There are some spelling pictures in the jigsaw puzzle.

1. Tangram consists of seven boards, through which many figures can be spelled out. It is an intellectual toy circulated by the Han people, so it is also called "wisdom board". With the jigsaw puzzle, you can spell out patterns above 1600, and human innovation is endless. I believe that the spelling of Tangram is gradually sublimating.

2. As a traditional toy puzzle, the complete pattern is square, and different puzzles will take on different shapes, but they can be triangles, parallelograms, irregular polygons, and of course they can also be combined into various shapes such as animals, figures, plants, buildings, letters, etc.

3. Tangram has the characteristics of simple structure, easy operation and easy understanding, and is deeply loved and welcomed by children and the younger generation. The spelling of Tangram also has the functions and benefits of visual discrimination, shape concept, visual memory, encouraging openness, hand-eye coordination, divergent thinking and creating opportunities.
