Tangram History Classroom: 1. Tangram, also known as Tangram and wisdom board, is an intellectual toy spread among Chinese folklore. In the Song Dynasty, there was a man named Huang Bosi, who was very interested in geometric figures, and he was hospitable, inventing a kind of "banquet table" composed of six small tables - a small table for inviting guests to dinner.

2. Later, some people improved it into a banquet table composed of 7 tables, which can be combined into different shapes according to the different number of diners, such as 3 people into a triangle, 4 people into a square, 6 people into a hexagonal ......In this way, it is convenient for everyone and the atmosphere is better. Later, someone changed the size of the banquet table to only seven boards, used it to puzzle pieces, and evolved into a toy. Because it's so clever and playful, people call it "Tangram".
