"Little, grass" Leilei's little face was so angry that he couldn't even see it. It was obviously a little grass, so this kid did not forget to bring out the initiator and say, "Mom, I'm teaching."

Ning Yunxi only has one feeling at this time, and he can hit the wall

Meng Chenyi's shoulders were shaking, and he couldn't resist the sound in his mouth. Seeing that his nephew was about to get even more angry, Meng Chenyi hurriedly comforted the child and said, "Leilee, wait, Second Uncle gave you a good thing."

After giving his father a gift, the second uncle gave him another gift. The little face turned sad to joy. He looked at his second uncle expectantly.

Meng Chenyi only knew that his nephew must have no talent for painting, so he rushed into his room and took out some tools.

Everyone looked at it as mathematical drawing tools, such as compass, triangle boards, rulers, etc.

Meng Chenyi taught his nephew to draw a triangle along the shape of the triangle board with crayons and asked his nephew, "Does Leilei know what this is?"

"triangle."

"Leilee, do you actually know triangles?" The little girl Meng Chencheng asked with her big eyes in surprise.

What's the problem with Leilei giving his aunt a calm look?

Meng Chenyi was also a little surprised. After thinking about it, he drew a trapezoidal shape and asked his nephew, "Leilei, what is this? Do you know?"

"Right-angle trapezoid." Leilei answered effortlessly, and his little head seemed to have no need to blurt out the answer.

It was shocking. If a two-year-old child could understand the same thing as trapezoids, it would definitely be unusual for him to distinguish right-angle trapezoids. Meng Chenyi was a little stunned for his nephew.

"It's strange." Meng Chenjun rushed back and said, "I taught him that one plus one equals two before, so he understood why he could understand these graphics."

These people don’t think about it. When this kid pesters his mother every night, he is arranged by his mother to watch his mother prepare lessons on a small stool next to him. It is estimated that Ning Yunxi forgot that he has answered countless graphic questions asked by his son.

Mom, what is this

Right angle trapezoid.

Mom, what is this

Polygon.

Mom, what is this

Parallel lines.

Mom, what is this

Cylinder.

Maybe the painting is not very good, but I have a natural memory of mathematical graphics. After reading it, my mother said, she actually remembered it.

Ning Yunxi was also a little surprised because she had never thought in her heart that her son had to learn from her or her second uncle.

Thinking about it again, it is actually not difficult to realize. The things my son likes to play most since childhood are origami, not other things. Whether it is building blocks or origami, they are inseparable from changes in mathematical graphs.

Studies have shown that children who play well with building blocks will be better than other children in mathematics. Origami is one of the tools used by mathematicians to solve world problems.

"Leilei is" the little girl Meng Chencheng asked her fourth brother nervously.

Meng Chenjun raised his finger to his sister and shrewd, saying that his elder brother and sister-in-law didn't like to praise his son too much, and did not like Leilei to be too proud and complacent.

But Meng Chenyi couldn't suppress his happiness and took out other math treasures from his room to tell his nephew one by one.

Seeing that his son and his second uncle were having fun, Ning Yunxi stood up.

The sound of cars came from downstairs, as if her husband had returned.
