Spring Festival is a traditional festival in China, and people in China will celebrate this special festival in various forms. If you look carefully, there are also many mathematical elements in the Spring Festival. This winter vacation, the fourth-grade students will have a special assignment-looking for the beauty of graphics in the Spring Festival, combined with the part of the next book "The Movement of Graphics".
? Some students use hand-painted form, and more students use paper-cut form. When handing in the works, the students couldn't help talking noisily: "Teacher, you see, the window grilles have different shapes, but they have one common feature-they are all axisymmetric figures." "What you said is not complete. Take a closer look. The pattern with the same shape in the window grilles can be regarded as the rotation of a pattern. "
?
? Song Wenxi took advantage of this because of his high height. She attaches great importance to her work. "I cut a Chinese knot, which is not as complicated as a real Chinese knot, but it is also an axisymmetric figure."
? Miao Xi said, "Look at the two lanterns I cut together. On the whole, they are an axisymmetric figure, but separately, they are the translation of a lantern. " After listening to her description, I was pleasantly surprised. This girl, who doesn't even talk much at ordinary times, has expressed herself so thoroughly and her face is full of confidence.
? Watching them talking and laughing, I suddenly realized that such a special assignment brought them not only knowledge, but also a pair of eyes to discover beauty. The graphic beauty of the Spring Festival allows students to feel the beauty of the festival as well as the beauty of mathematics and the close connection between mathematics and life. Let students feel the unique charm of mathematics through interesting homework, which is exactly the original intention of our design of this homework.
