If there is no positive portrait or other obvious reference in the math topic, the left and right directions are judged from the perspective of the questioner by default. If there is a clear task or reference in the topic, it is necessary to distinguish the left and right directions by the standards in the topic.
Primary school mathematics problem-solving skills;
1, read the question carefully.
You usually read the questions three times. The first time you know what to say, the second time you have to read them with questions. At this time, you should read slowly, think while reading, circle the places you think are important, think about what conditions the questions in the question need to put forward, and analyze the quantitative relationship between them when reading for the third time.
2. Analyze the quantitative relationship.
It is best to use the manuscript paper to analyze the topic. You should write and draw on the manuscript paper. You can extract keywords and draw line segments. Some topics can also be demonstrated in kind and performed by yourself, which is intuitive and easy to remember.
3, list the formula calculation
After analyzing the quantitative relationship, you can use the column chart to calculate. If you usually do problems, you can also think about how to solve them, so that a problem can be analyzed and solved in different ways from different angles, so as to achieve the training of multiple solutions to one problem and expand the thinking of solving problems.
4, the inspection is correct
After the topic is finished, you should review the problem-solving ideas and see if each step is reasonable. When reviewing our thinking, we can change our thinking to check whether we have done it right or not. Starting with the problem, we can start with the conditions.
