The first step is preview. Preview time doesn't take long, 5- 10 minutes is enough. Understand the key points of the content to be learned, recall the old knowledge related to the content of this lesson, and forget to review it in time.
The second link is to attend classes. Listen carefully in class. Don't think that elementary school mathematics is simple or you have a preliminary preview, just because you know everything, and then you are distracted from doing other things. I don't know the key is the words you missed, which is why you made a mistake in practicing the exam.
The third link is review. Remember not to review or do your homework. Before doing exercises to consolidate, you must review what you learned that day.
The fourth link practices consolidation. It is necessary to do problems properly in mathematics learning, and it must be done thoroughly. If you do it thoroughly, you will truly understand it. If you do it thoroughly, you will be able to draw inferences. Please pay attention to the following points when practicing:
(1) Collect wrong questions. There are two kinds of wrong questions, one is that you don't know at all and have no idea. The other is because of carelessness. I think the most valuable is the second category, which deserves your analysis and reflection. Through analysis and reflection, when you start the next exam or practice, you can take a deep breath and think about what mistakes you made because of carelessness, so as to tell yourself to pay special attention to ensure that similar "careless mistakes" will not happen again.
(2) collect questions. The problem may not be difficult, but it has a clever solution, but you just didn't think of it. The problem may be the expansion of textbook exercises, which can broaden your mind. You should collect such questions in the problem book and review them frequently, which will greatly promote the improvement of your math scores.
(3) do exercises. Some students look at the problem rather than solve it when they are doing topics other than those assigned by the teacher. When doing a problem, we often encounter such a situation: I have seen this problem without problems, but I can't do it in the middle. The reason is that I read the exercises at the beginning and ignored the down-to-earth steps.
The great scientist Einstein gave a formula of learning method: W=X+Y+Z (success = effort+correct method+less nonsense). Students, remember that success belongs only to those who work hard.
Good luck! Learn and progress! ~~
