Liu Yangzi, Class Three, Grade Two.

One day, we happily went to pick strawberries in dad's car.

Along the way, I found that the car was translating and the wheels were spinning.

It turns out that there is mathematics everywhere in life.

Xue Yizhou, Class 3, Year 2

Today, my mother cleaned the living room downstairs and removed the sofa chair. I said to my mother, "Mom, I'll help you move." I moved the sofa chair back and cleaned it for my mother. She praised me as a good boy.

After dinner, I went to the opposite yard to play, where there were many fitness equipment. I stood on the rotating disc and thought it was very funny.
