From school to now, we are immersed in the classroom almost every day. These classes are interesting, serious, vivid or thought-provoking, and among so many classes, my favorite is that math class. At first, I was not interested in math class, and I didn't raise my hand to speak. This teacher is different from other teachers in class. He smiled happily, so I like math. It turned out that mathematics was not as difficult as I thought, and then I slowly began to like mathematics and began to raise my hand to speak. The teacher's humorous and vivid explanation is very infectious and brings us to an emotional art palace. One of the math classes is really hard to forget.

With a burst of wonderful music, Mr. Qu walked into the classroom with a brisk pace and said with a smile, "Students, do you like watching the Journey to the West?" "I like it." The students said in unison. The teacher showed us the Monkey King's seventy-two comic books on the big screen of the school. After a while, the teacher asked us to sit down, and everyone was still unfinished, looking back on the interesting things just now. "Quiet, class begins now!" "Which character in The Journey to the West do you like?" Teacher Qu said humorously. The Monkey King! Everyone said without hesitation. I thought to myself: Why did Teacher Qu ask us this question?

"There are seventy-two changes in the Monkey King, right!" Just as I was wondering, Teacher Qu went on to say, "In fact, in our huge mathematics kingdom, we should be as flexible as the Monkey King."

Speaking of this, Teacher Qu drew a rectangle, a square, a parallelogram, a triangle and a trapezoid on the blackboard, and then asked everyone, "We will all find the areas of rectangles and squares, but will you find the areas of the following figures?" Everyone touched their heads and looked at each other. The teacher continued: "Today! We will calculate the area of the parallelogram. "

As soon as the voice fell, Mr. Qu drew several parallelograms on the blackboard, and then drew them higher. Then, Teacher Qu asked us to draw the height of the parallelogram in the book, then cut it out and spell it on the right. Suddenly, the parallelogram became a rectangle.

"This is called transformation." Teacher Qu paused and said, "There are four steps in transformation: painting, cutting, moving and spelling." After listening to Teacher Qu's words, I suddenly realized.

The length of the original rectangle is equal to the base of the parallelogram, and the width of this rectangle is equal to the height of the parallelogram. Because the area of a rectangle is equal to the length x width, the area of a parallelogram is equal to the base x height.

"Didi!" The bell rang, but I couldn't bear to leave it. The teachers in this class are very kind. How harmonious the atmosphere is; How happy I feel! This is my favorite math class! This math class makes me unconsciously learn knowledge in happiness, which is really hard to forget! I like this course because it has a challenging class form; I like this course because the teacher is very persuasive; Before that day, I didn't expect such a positive and harmonious class in a math class, which really surprised me. The classroom will be very attractive. I like this course, and I like the classroom atmosphere where you chase after me. As long as you learn every subject well and cultivate your wider interests, you will be able to fly in the sky of mathematics! Because of this, I can enjoy such a wonderful math class.
