Mathematics is closely related to our life. On the road, in the market, in schools, everywhere. What time do students have classes every day? How long do students study every day? How long is the break? Simple and trivial problems like this constitute a series of beautiful and wonderful mathematical problems in the vast world. From the high-coast redwoods to the giant California redwoods, they are the oldest creatures on earth. You can find some mathematical concepts such as concentric circles, concentric cylinders, parallel lines, probability, spiral, ratio and so on. Another example is a common example in life. Different shapes and styles can be folded with an ordinary square. Hua once said: "The universe is big, the particles are tiny, the speed of rockets, the cleverness of chemical engineering, the change of the earth, the mystery of life, the complexity of daily use, and mathematics is everywhere." The last sentence of this sentence touched me deeply. There is mathematics in life, and mathematics is the most used in life every day.
But now the flowers of the motherland, but with what attitude to face the mathematics in life?
Bank interest rate, stock ups and downs, clothes discounts, ball game scores … these words closely related to life appear in textbooks. Some students who lack common sense of life are confused again and again, and often don't even understand the topic: what is interest rate? Is it cheaper to buy clothes at a 60% discount or at a 60% discount? "It is difficult for students who study behind closed doors to learn math well now," everyone said.
Education experts pointed out that the previous exams overemphasized problem-solving skills, and the test questions were artificially fabricated, deliberately setting traps and obstacles, which led to mathematics education becoming problem-solving training and students being caught in a naval battle.
Nowadays, application problems are not only long, sometimes reaching more than 200 words, but also closely related to life, which requires mathematical thinking to solve problems in life. Therefore, students need to cultivate such a thinking mode: after understanding the common sense of life and reading the content of the test questions, they can turn practical problems into mathematical problems, establish mathematical models, and finally put the answers into life. Students should have the idea that mathematical problems help us solve practical problems, pay attention to mathematical problems in life and consolidate them through relevant training.
So how to cultivate students' practical ability in life? I think the real way to learn mathematics well is not to memorize definitions and rules, but to use knowledge flexibly and apply it flexibly in life. Things that are often overlooked will always appear unexpectedly in front of you during the exam, which will make you unprepared. Therefore, everything and every object in life should be carefully observed, and mathematics in life should also be carefully observed, combined with the knowledge in textbooks, in order to achieve twice the result with half the effort. I found the answer online. Some parents train their children to solve problems in simple but practical ways. In the first grade of children, parents take their children to buy vegetables every day, so that children can directly discover the existence of mathematics from their lives, and let children accurately calculate how much it costs to buy vegetables, and which dishes are good and cheap; When the child is in the third grade, parents can take the initiative to ask the child to be a "small calculator" at home, responsible for the calculation and payment of water and electricity bills at home; In the fifth grade, let children solve practical problems independently and exert their potential; In the sixth grade, parents always took their children with them when they went shopping. Is it cheaper to get a 20% discount or buy one and get one free? And so on.
Only by truly understanding and discovering mathematics can we fall in love with mathematics.
