How wonderful and happy mathematics is! I'll help you with your math! Since I entered the new semester, I have made a plan to study mathematics. In these three weeks of study and life, I gradually mastered several coup! I'll share it with you now! Coup1-I am soaring in control of the classroom. First of all, it is very important to seize 40 minutes in class. What is said in class is the essence of knowledge. Only by listening carefully and speaking actively in class can we lay a solid foundation for this kind of topic, this kind of topic and the knowledge content of this chapter. Just like Gai Lou, we must lay a solid foundation first. In this way, the completed building is firm and unbreakable. In class, we should follow the teacher's ideas. Think carefully about each problem, think about why you should do it, and then practice solving such problems. What the teacher says in class is very important, so we need to practice more and master these important knowledge firmly. Coup 2-Two Habits It is very important for us to master the two habits of preview and review. Why do you say that? First of all, we should preview the textbooks and preview this knowledge in advance. In class, you can also compare the problem-solving methods with the teachers to see what is the difference. If not, think about which is simple and which is correct. This kind of preview has a good effect on our study. As for review, we need to consolidate what we have learned and do some exercises with the class. In this way, we can not only review what we learned in one day, but also test how we learned today through practice. In some places, if you have mastered it, you should check for leaks and fill gaps and learn this knowledge by yourself again. Coup 3-Happy study. I am the best. Finally, I have to do some Olympic math problems every once in a while to improve my application problems. For example, we are studying fractional multiplication now, and there is a very classic topic in my teaching assistant: there is a bus with a speed of 20km/h when the wind is downwind, and it is 15km/h when the wind is headwind. It takes seven hours for this bus to get from A to B. What is the average speed of this bus between A and B? I thought about it and an idea came to my mind. Can it be calculated as follows: the distance between Party A and Party B is "1", the time to go is 20 minutes "1", and the time to return is 15 minutes "1". The time to go is 1 times 3, and the time to return is 1 times 4. It is inferred that the bus travels with the wind for 3 hours and 4 hours, and the distance between Party A and Party B is 3 times 20 or 4 times 15=60 kilometers, so the bus is * *. After finishing this problem, I carefully sorted and analyzed it again, and finally understood it thoroughly. I had a rude awakening, suddenly realized, summed up this kind of problem, and finally mastered the practice of this kind of problem. Mathematics study is my unique skill, and relaxing mathematics is wonderful! Mathematics paradise, with a wide range of interests! I am the best, I am the strongest!
