Math Manuscript for Grade Six 1 1
The content of the sixth grade mathematics handwritten newspaper 1:
Recently, we learned how to calculate the volume and surface area of cylinders and cones. I studied the knowledge in class seriously and did some extracurricular exercises to consolidate what I learned. On the basis of comprehensive study and practice, I have summarized the relevant knowledge: there are six main aspects in this respect:
One is volume. Is to roll a rectangular paper into the shape of a cylinder, and then calculate the maximum volume of the cylinder. For example: length 12, 56 meters, width 9. The 42-meter rectangle is rolled into a cylinder, and the overlapping part is ignored. Find the maximum volume of a cylinder. There are two possibilities for this kind of topic, that is, a long circle or a wide circle. Therefore, we should solve these two possibilities and compare them. What needs attention in this topic is that it must be clearly seen that it is rolled into a circle with the length and width of a rectangle respectively.
The second is to turn. That is, a rectangular piece of paper is rotated 3600 degrees along one side to find the volume or area of the final shape. For example, a rectangle with a length of 8 cm and a width of 5 cm can be rotated around its length to calculate the volume of this shape. Rotate a rectangular piece of paper once to get a cylinder, and then use the formula for calculating the volume of the cylinder to get the answer. Pay attention to what shape of paper this topic is rotated with.
The third is cutting. It is an object with a shape. According to certain rules, part of it is removed and the volume or surface area of the remaining shape is calculated. It should be noted that all possibilities should be calculated, and only one can't be lazy.
The fourth is casting. It is to melt an object of one shape into a liquid and then recast it into an object of another shape. This kind of topic should grasp the key points. Although the shape changes, the volume will not be considered.
The fifth is to increase. Is to continue adding another shape to one shape. We should pay attention to what shape is added.
The sixth is cutting. That's right. Cut a shape into several sections, and then tell you what to add and how much to add, so that you can work out the principle. You should see clearly how this kind of topic is cut, what changes have taken place after cutting, how to increase the area and so on.
The above is my summary and reflection on the contents of my recent study. Do you find mathematics mysterious and interesting?
Sixth grade mathematics handwritten newspaper content 2:
Before the Spring Festival this year, we went back to my grandmother's hometown-Dianbai. There are beautiful scenery, birds and flowers, surrounded by mountains and a big reservoir. People here all eat their own vegetables. Almost every household has a large vegetable field.
On this day, we asked grandma to take us to see her vegetable fields. When we came to the field, at first glance, green came into my eyes, just like flawless jasper. Take your time, there are all kinds of vegetables in the field. Suddenly, my grandmother asked me, "Xianxin, I want you to calculate the area of this land." This field is trapezoidal, 9 meters up and down. " The bottom is 14 meter, and the height is half of the bottom. So what is the area of this field? "I think we can directly use this semester's' knowledge: trapezoidal area = (upper bottom+lower bottom) × height ÷2', and then first calculate the height: 14÷2=7 (meters), and then calculate it according to the trapezoidal formula: (9+14) × 7 ÷. 5 (square meters) finally equals 80. 5 square meters, so I answered my grandmother: "This land is 80. 5 square meters. " Grandma said, "Well, that's right. Then, if Chinese cabbage is planted in this field, and each plate covers an area of 225 square centimeters, how many Chinese cabbages can be planted in this field? "I had a brainwave: turn 225 square centimeters into 0. 0225 square meters. Then 80. 5÷0。 0225≈3577 (tree). Grandma said with relief, "Well, yes, yes. It seems that you are good at math. You know, mathematics is very useful in life. " I smiled and nodded.
Mathematics is everywhere in our life, so we must learn it well.

I saw a topic "Mathematics in Life" in my math textbook today. The topic is: "China's population is about 654.38+0.3 billion. If we save 654.38+0 cents per person per day, if so, our country will save about 6.5438+0.3 million yuan. If primary school students need to save about 65438+ tens of thousands of dollars from grade one to college, then this money can be provided to 1805 children who are out of school and have no money to go to school. Wouldn't it be nice to give these money to those people? "
After reading the above information, I thought: many hands make light work. Suddenly I remembered, many hands make light work? Not good, because I thought about it: if this population of about 65.438+300 million wastes 65.438+0 drops of water, then a * * wastes about 65.438+300 million drops of water, then what do you think is 65.438+300 million drops of water?
I did a small experiment: I put 1000 drops of water under the tap and weighed them with a scale. The weight of 1000 drops is 200 grams. I wrote another calculation.
130000000÷1000× 200 = 260000000 (g)
260000000 grams =260 tons
I really don't know, it's shocking: if everyone uses one ton of water a month, then 260 tons of water can be used for two years. I went to ask my father, "How many kilowatt hours can a ton of water generate?" Father said, "1 ton of water can generate 100 kwh of electricity." This means that 260 tons of water can generate 26,000 degrees of electricity.
Wow! I was shocked at once. 260 tons of water can play so many roles! So we should save all the water now, don't waste a drop of water, we should form a good habit of saving, and we can't waste any more.

In the afternoon, my father came back from Shunde. After dinner, my father said, "Feifei, let me test your math, ok?" I patted my chest and said, "No problem!" My father said, "I got a raise this month. I earn more than your mother. Our monthly salary adds up to 3500 yuan. The monthly salary is poor, 300 yuan. How much do you think I get a month? " After listening to my father's words, I began to draw line drawings on paper to help me understand.
I worked out the answer quickly and told my father. First of all, the mother's salary is as much as the father's, so the monthly salary of father and mother is 3500+300=3800 (yuan), and then the total monthly salary is divided into two parts, 1 part is the father's monthly salary. It is 3800/2= 1900 (yuan).
Hearing this, my father nodded with satisfaction. At this time, my mother, who was cooking, said to me, "Do you have any other methods?" I stopped to observe and think again. I found that the key to this problem is to find out who is the standard. Different standards have different methods. So, I have a second method: "It is based on the mother's salary, assuming that the father and mother's salary are the same, then the sum of their monthly salary is 3500-300)=3200 yuan, and then the sum of monthly salary is divided into two parts on average, and the part of 1 is the mother's monthly salary. Finally, in 300 yuan, who has more fathers than mothers, is the father's monthly salary, 3200/. Hearing this, my father nodded with satisfaction. " It seems that the Olympic math class is not in vain! Ha ha! "My father also praised me because math helped me!
