It is not tiring to finish homework quickly.
1. Before you do your homework, review what you learned today. If you know what you are doing, you won't work hard. Do your homework and don't give up. Don't treat homework as a task. Try to make nutritious bread and absorb it. I can rank in the top five in my class every day.
2. You must write your homework, although sometimes you will feel that some homework left by the teacher is useless. Indeed, sometimes the teacher asks me to copy words and texts. Of course, it's no use just writing. While writing with your brain, you will soon finish it and remember it deeply.
I sometimes listen to music when I do my homework, but don't listen to what you particularly like, because it will be easy to sing along unconsciously and slow down my homework. Just pick a few rhythms that are always sweet.
Nowadays, students have a heavy burden. In fact, they want to write faster, but they don't want to copy other people's answers when they go to school the next day. There is a good way to write with classmates. You can see him or you can see him. If you don't understand, both sides can explain to each other. Although there is suspicion of plagiarism and writing, it can really urge them to make progress together.
What are the methods and skills to learn math well?
Mathematics is not taught, but realized and taught by oneself. Mathematics is not knowing how to read, but knowing how to calculate. The most important thing in learning mathematics is the ability to solve problems. At the same time, we should listen carefully in class, do supporting exercises after class, and learn to change with constancy.
The simplest learning method is "enlightenment", that is, thinking hard and learning a mathematical concept. In addition to understanding what this concept means, you should do exercises to deepen your practice. Many people don't reflect after problems, that is, they don't think about why they are wrong. What caused this mistake, how to avoid this problem next time, and how to summarize it.
Grasp the classroom. Science study focuses on weekdays and is not suitable for surprise review. The most important thing to study on weekdays is to attend class for 45 minutes. Listen attentively and keep your thoughts close to the teacher. Finish homework with high quality. When writing homework, sometimes the same type of questions will be repeated. At this time, we should consciously check the speed and accuracy, and we can have a deeper thinking on such problems every time we finish.
For the wrong questions that can't be done: understand each step and think about why; If this happens frequently, it is necessary to change the calculation methods and habits, such as learning to check the calculation twice to improve the accuracy. The point is to think! The deeper you think, the more thoroughly you learn, and you can get high grades with a small number of questions. But this idea is not out of thin air, but based on the wrong question. Learn from your mistakes and make up for your own shortcomings, and you will make fewer and fewer mistakes next time.
