How to teach fifth-grade mathematics well
As an important part of culture, mathematics plays an extremely important role in improving people's comprehensive quality. Here I talk about how to teach primary school mathematics well from two aspects: First, talk about the cultivation of good study habits in primary school mathematics teaching. \x0d\ Primary school mathematics syllabus regards "cultivating students' good study habits" as an important aspect of quality education. Russian educator ushinski once said, "Good habits are the capital that people store in the nervous system. This kind of capital keeps increasing in value, and people enjoy its interest all their lives. "This shows that good study habits of primary school students will play an important role in his future development. Therefore, it is an important duty of every math teacher to cultivate students' good math study habits in primary school. \x0d\ (1) Cultivate students' habit of reading math textbooks carefully. In primary school mathematics teaching, we should pay attention to cultivating students' habit of reading mathematics textbooks and let them read textbooks. Mathematics class should combine students with "watching, reading, thinking and practicing". From the moment children enter school, we should guide students to learn and understand pictures, tables and words step by step, and then guide students to understand terms and keywords, thus causing students to think. With the continuous improvement of students' age and abstract ability, more specific requirements are put forward for the content of teaching materials, so that students can develop the habit of reading first and then doing homework. \x0d\ (2) Cultivating students' habit of carefully examining questions is an indispensable link in correct calculation. Through the training of examining questions, we can cultivate students' serious and rigorous habits, guide students to choose correct and reasonable calculation methods flexibly, and improve the quality and speed of doing questions. 1. When writing a question, students should first read the requirements of the question and correctly understand the meaning of the question. This requires teachers to pay attention to cultivating students' ability to read and understand questions in peacetime, make clear what we should do and how to do it in the questions, and then calculate. 2. Teach students to observe the types of questions, correctly apply the rules and properties, and make the calculation simple. 3. The examination of the problem should always run through the whole process of solving the problem. We should not only look at the whole question, but also look at the new figures and new situations that appear in the operation process, so as to achieve proper methods. Correct exams can ensure correct and fast problem solving, so it is very important to cultivate students' good exam habits. \x0d\ (3) Cultivate students' habit of thinking diligently. In the final analysis, students' learning mathematics is a kind of thinking activity. Only by being diligent and willing to think can we understand and master mathematical knowledge and form various mathematical abilities. Teachers should first pay attention to stimulating students' thinking desire, be good at asking questions that inspire students to think, and form students' good quality of finding and asking questions; Secondly, we should pay attention to providing appropriate thinking basis and cultivate students' well-founded, organized and orderly thinking habits; Seek solutions to problems from multiple angles and promote the gradual improvement of thinking level. \x0d\ (4) Cultivate students' habit of conscientiously and independently completing homework and consciously checking. Students' homework reflects their learning attitude and habits. Good work habits include: serious attitude, timely check, neat handwriting, independent work, originality and so on. From the day when students first enter school, it is necessary to cultivate correct writing posture, requiring neat handwriting and standardized format. From numbers to numbers, from one digit to multiple digits, from integers to decimals and fractions, strict requirements should be imposed. Finishing homework independently is the realistic guarantee to play its due role. We should always praise those students who can overcome difficulties and carefully check their homework to prevent and correct the bad habit of copying others' homework. Habits are formed through long-term practice. Therefore, cultivating students' good study habits must run through the whole process of mathematics teaching. Only by adhering to strict requirements, demonstration and induction, and repeated training can we achieve the expected results. \x0d\ II。 Stimulate students' thirst for knowledge in mathematics teaching \x0d\ (1) Cultivate students' learning motivation. Learning motivation plays the role of starting, maintaining and guiding in mathematics learning activities. Therefore, in teaching, we should pay attention to the characteristics of mathematics content itself, stimulate students' learning motivation, create situations and induce students' learning desire. \x0d\ (2), cultivate students' interest in learning Only when students are interested in what they have learned can they stimulate their desire to learn and make them think hard and become the masters of learning. \ x0d \ 1。 Digging the inner charm of mathematics knowledge to attract students. \x0d\ The rigor and systematicness of mathematical knowledge, the organic connection between various mathematical materials, the open thinking of solving problems and the formation of various special and ingenious mathematical thinking constitute the potential attraction of mathematics itself. In teaching, we should pay attention to using this inherent charm of mathematics to guide students to associate, discover and apply. For example, when teaching "fractional application problems", I first showed a sentence: "A number is 25 of B number". Q: "Students, what do you think from this sentence?" The students immediately scrambled to raise their hands. Some say, "I think the number B is the unit' 1', and the number A is 25 of the number B", while others say, "I think the number A is the unit'1',and the number B is 2 12 times of the number A". Find out the thinking method of the unit "1"from different angles, so that \ x0d \ 2。 The application of intuitive teaching stimulates students' knowledge consciousness. \x0d\ Children are curious and active, and their thinking mainly focuses on specific images. Organize students to observe and operate purposefully in the teaching process, and stimulate students' desire to find and think about problems. For example, I taught this part of knowledge when I was teaching the Preliminary Understanding of the Circle. The circle is an axisymmetric figure. Take out a cut paper circle and ask, "Who can quickly find the center of the circle with the knowledge learned in this lesson?" After careful observation and thinking, one of the students stood up and demonstrated while talking. He folded the paper circle twice, pointed to the intersection of the two creases and proudly said, "This is the center of the circle!" " "Inspired by this classmate, another classmate found the center of the circle in a simpler way. In this way, students are deeply impressed with what they have learned and have a firm memory. \x0d\ (3) Cultivate students' sense of competition \x0d\ In primary school mathematics teaching, make use of primary school students' curiosity, competitiveness and psychology to conduct various forms of competitions in a timely and appropriate manner, such as "seeing who is faster".
