Reflections on Reading 《 Primary School Students' Mathematics Newspaper 》
Article 1: Today, I read the math tabloid at home. What's in the math newspaper is really amazing. A few simple strokes profoundly describe the interest in mathematics. Only then did I know that mathematics is a big paradise. Although math is interesting, it sometimes makes everyone feel bored. For example, some topics are easy, so we find them interesting. On the other hand, some topics are relatively difficult, and some students will show embarrassed expressions. Life is full of mathematics, for example, we have just learned a lot about angles in our life. On the clock face, 1 and 2 points form acute angles, 3 points and 9 points form right angles, 4 points and 5 points form obtuse angles, 6 points form right angles, and 12 points form rounded corners, in which straight, flat and circular triangles are fixed degrees. Mathematics is needed everywhere in life. If students go to the movies, count the number of people to prevent waste caused by fewer people and more cars. For example, if you want to lay a sewer pipe, you must know the length of laying, so as not to affect the progress of the project because of insufficient materials. There are many mathematical problems in our life, and only by constantly discovering and solving them can we get the pleasure of mathematics. Article 2: Today, because I have no homework, I have nothing to do. Under the "coercion" of my parents, I took out the math newspaper for primary school students, which I don't usually read. Suddenly my eyes lit up and I accidentally saw an article "The simplest replacement method". This is an article about how to calculate cubes. Usually when I do this kind of questions, I count them one by one from top to bottom or from left to right. Once there are more cubes in the graph and the graph becomes complicated, it is easy to make mistakes. Every time I do ten such questions, I make one or two mistakes. I am very happy to read the article "The simplest substitution method" today. This made me "enlightened" and I realized that I usually do this kind of problem. The article is introduced as follows: "Move the extra cubes of each layer to the gap of another layer to make the cubes of each layer equal, and then multiply the number of each layer by the number of layers to get the total number of cubes." I tried to do a few questions for my father in this way. As a result, my father said they were all fine, and I was extremely happy. I finally learned to count cubes. I am ashamed of what happened today. Every time I order study materials, I am very active, clamoring for my parents to order them for me, but I seldom read them myself. Every time I take them home, I throw them on the table and it's over. I secretly made up my mind that I must read more study materials I ordered in the future, so that they can be fully utilized and not be allowed to "sleep" at home. I hope students like me can make full use of your study materials quickly. I believe that you will also have unexpected gains like me. Article 3: Last semester, under the introduction of teacher X, I took part in the study of primary school students' mathematics newspaper. Every question and every formula in primary school students' math newspaper attracts my attention like a magnet. Gradually, primary school students' math report has become an indispensable part of my life, and I am very excited to learn every problem. The world is full of wonders, and there are many interesting things in our mathematics kingdom. Don't think so complicated, simplify the problem, find out the equivalence relationship, and the problem will be solved. For example, there is a problem in self-exploration: A and B start from the east and west at the same time, and walk in opposite directions. The distance between the two places is 10 km. A walks 3 kilometers per hour and B walks 2 kilometers per hour. A set off at the same time with a dog. The dog ran to B at a speed of 5 kilometers per hour, and immediately turned back to A after encountering B; Run back to B when you meet A, and the dog won't stop until A and B meet. Q: How many kilometers did the dog run? The key to this problem is to find the equivalence relation: no matter how the dog runs back and forth, the running time is the same as the time when A and B meet. The meeting time of A and B = 10/(3+2) = 2 (hours), so the distance that the dog runs is: 5 * 2 = 10 (kilometers). The Pupils' Mathematics Newspaper has been with me for many days and nights. It taught me the idea of solving problems and made me rush to the world with infinite knowledge in my mind again and again; Improve my ability to explain and make the steps to solve the problem clear; It has enriched my horizons, and made me understand the quick and ingenious calculation, travel problems, profit and loss problem, and herding cattle ... Each issue of the collection of essays by famous scholars is also my favorite section, which can help me understand a certain truth from the feelings of famous scholars, learn how to learn how to learn Olympiad better, know how to solve problems, and arrange and enrich my after-school life more appropriately ... I want to thank the math journal of primary school students, which has brought me infinity. & lt/SPAN>。 & lt/SPAN>。
