Math composition for the first grade 1 Learn everywhere, math is very useful in life! As long as you pay close attention to the things around you, you will find that.
Yesterday, we went to a very remote place, where we set out with a map. My mother patted me on the shoulder and said with a smile, "How far is it from home?" I thought about it, picked up the map and glanced at it with my eyes like a copper basket. My searchlight stared at several numbers and immediately calculated the proportion with what I had learned. I was shocked.
It's so far that we have to drive for hours. Mother nodded happily. Dad counted it again: "We still had 180 liters of gasoline when we set off. If the car doesn't refuel at the destination, there is still 15 liter of oil. How many kilometers did you drive? " I said, "It should be 1237.5!" Dad nodded his head.
Math is really useful. Learning is everywhere, and mathematics is everywhere.
My math teacher, with black hair, is tall and walks like the wind. She looks anxious and fast.
In class, she always waits for the whole class to arrive before giving a lecture. If classes start when there is not much time, teachers who walk slowly always start classes as soon as they arrive at the classroom. Wu teaches. Sometimes students don't understand her, she won't scold, but the teacher will scold us.
She is worried that we will miss class. If you study well, Mr. Wu will say, "Oh, why do you study so well?" If she doesn't study well, she will say, "How did you get so few points in the exam?" She also criticized me because I sat with Wu Huiling and got 99 points instead of 100. She asked me why I didn't get 100, but I didn't say anything.
My math teacher's name is Zhang Xiuhua. He is tall with a white face and wears a pair of glasses. He looks very serious. We are all afraid of him.
For disobedient students, he will knock his hand with a ruler, but it doesn't hurt at all; For students who are obedient and study well, he will praise him with a smile and say "great"!
His class is so good that we all like it. We all like our math teacher. I think he is a qualified teacher. I really want to say to him: Teacher, you have worked hard!
I had an interesting math class this morning.
In math class, I prepared colored paper and scissors. First, the teacher told us what the symmetry axis is, and let us understand what the symmetry axis figure is. Then, the teacher asked us to take out colored paper and scissors to cut out our favorite symmetry axis figure. I cut a small skirt and the teacher put it on the blackboard. Very beautiful.
In this math class, I not only learned the symmetry axis figure, but also was very interesting.
This week's math class is about the same number of items in sequence, that is, the same number of items in sequence. I counted it carefully in case I missed one. After coming home from school, I began to count refrigerators, televisions and so on.
Grandma asked me what I was talking about! I have learned more than that since then. I found that there are more pink things in Tong Tong's house, but mine are less. There are many blue things in my home, but few red ones. Tong Tong's father has many books, but my father has few.
I have as many books as Tong Tong. These are all things that kindergarten can't learn, so interesting! I especially like math class!
In the afternoon, when we were having a math class, a bee suddenly flew out of the window and made a buzzing sound. Unexpectedly, it stopped firmly on my pencil case. I'm afraid I'll be stung by bees. My deskmate Zhang Yibo saw it and swept it away with a book. I thought, hey, this little girl is really amazing.
As a result, the bee didn't fly far, but stopped at Li Yixin's desk behind me. I saw Li Yixin hit it hard with a pencil case and wiped it off. The students in our class are really courageous!

Today, my mother asked me a question: If I give you a bottle, how can you hold half the water without any tools?
I can't remember from left to right, when my mother reminded me, "What shape is the bottle from the front?"
"Cylinder."
"The cylinder is a three-dimensional figure. What can you see if it is a plane figure? "
"Rectangular."
"Then let's play a game."
"good"
The tools prepared are: blue ink, cylindrical bottle and magnetic bar.

Loading water
rectangle
Through this little game, I understand that the area of a triangle is half of a rectangle with equal base and equal height, and the area of a triangle is half of a parallelogram with equal base and equal height.
The second class on Thursday is math. After the math teacher came to the classroom, he gave us an example.
It's about' 0-9 each number can only be used once', so let's do a type problem.
The teacher gave me this example, which made me feel much better. I think my math teacher speaks very well. After class, I told my classmates: The math teacher speaks very well, so we must listen carefully in class.
