This algorithm belongs to the Olympic mathematical thinking.

There are many ways to inspire thinking, not just sitting in the Olympic math class is the best way. Too serious teaching methods and boring brush questions will make children very tired. The most important thing of enlightenment is to cultivate children's interest in mathematics and have a natural dialogue with them anytime and anywhere.

For example, when telling children a picture book story, let the children count how many mice are in the book; When building blocks, hide the square and let him piece it together with two triangles; When eating cake on my birthday, I asked: 10 candles were lit on the table, and a gust of wind blew out three candles. How many candles are left on the table at last? When there is traffic jam on the road, it is a good way to cultivate mathematical thinking to look at the license plate numbers around and count 24 points with your children.

Graphic reasoning is the best tool to cultivate logical thinking ability. False is true false, true false is true. Logical thinking is thinking under the rule, and it belongs to unconventional thinking if it is connected with life. Everything seems to have nothing to do with life, but in fact it is within the scope of laws and regulations. The "crossing the sea from the sky" of logical reasoning can be described as varied, like a kaleidoscope, with endless changes and endless fun.

Geometry is a good tool to help them exercise their logical thinking, and the classic graphic reasoning questions always have their ideas, ideas and ingenious thinking; The classic is seemingly abnormal, and the actual solution is simple and clear. Therefore, it is very helpful for his logical thinking to train more graphic reasoning questions.
