1, strengthen basic mathematics knowledge: ensure that children master the basic concepts and principles of mathematics. These basic knowledge are the basis for understanding more complex problems. You can try to consolidate the basic knowledge by practicing simple topics.

2. Reading comprehension training: Mathematics is not only a calculation, but also an ability to understand relationships and concepts. Strengthening children's reading comprehension can help them better understand math problems.

3. Analyze problems: guide children to learn to analyze problems and understand the requirements and significance of problems. Let the children read the question many times, try to retell the meaning of the question in their own words, and then find out the solution to the problem.

4. Use concrete examples: When children are confused about some abstract mathematical concepts, try to explain them with concrete examples. For example, when explaining additive commutative law, we can use actual objects to demonstrate.

5. Do more exercises: It takes time and practice to understand math problems. You can let children do different types of questions and get familiar with the structure and solution of the questions through repeated practice.

6. Create a positive learning environment: maintain a positive learning environment, encourage children to ask questions, and encourage them to try to solve problems instead of criticizing them. This positive learning environment can help children face math problems more confidently.

7. Seek professional help: If the child's understanding ability continues to be poor, it may be necessary to seek professional education counseling or communicate with teachers to find out possible problems.

How to answer mathematical comprehension questions;

1. Read the topic carefully: understand every word and data in the topic. Especially the keywords in the topic, such as the most, the least, the inclusion, the exclusion, etc. Because these keywords usually indicate the direction and thinking of solving problems. If there are words or phrases you don't understand, you should look them up in the dictionary immediately, or consult your teachers and parents.

2. Find out the known conditions: find out all the known conditions in the topic and read it carefully. Usually, these conditions are given in the form of numbers, figures or words. Knowing these known conditions is the basis of understanding the whole topic.

3. Determine the question type: Determine what kind of mathematical problem the question belongs to. For example, it may be an algebraic problem, a geometric problem, a probability problem or other types of problems. This can help you choose the appropriate method to solve the problem.

4. Find out the relationship between the problem and the known conditions: understand the relationship between the results required by the topic and the known conditions. This can usually be understood by drawing, listing or text description.

5, the implementation of problem-solving steps: according to your understanding of the topic and known conditions, start solving problems. This may include the use of formulas, algorithms or other mathematical methods. In this process, you must think carefully at every step and don't skip any step.

6. Check the answer: After solving the question, re-read the question to ensure that your answer meets the requirements of the question. Sometimes, in the process of solving a problem, you may miss some information or misunderstand the meaning of the problem.

7. Reflection summary: After completing the topic, reflect on the problem-solving process and see if there is anything that can be improved. At the same time, summarize the problem-solving methods so that similar problems can be solved faster in the future.
