Expand the guidance of reading first-year math homework and do these five things well. It is very difficult to get poor math scores!
1 Read the questions three times and understand the requirements carefully.
First time: Read every word clearly. The child points to the text of the topic, the parents read one sentence, and the child reads one sentence after another. Sentences that are too long can be read two or three times.
This process is to let children see every word clearly, so that they can read it slowly or not. Children often read and read words, and will gradually understand them. After a period of time, children can read by themselves first, and parents can teach unfamiliar words.
The second time: read the requirements of the topic completely, talk about the meaning of the topic, and tick the keywords.
After reading it, parents should not be busy explaining the meaning of the topic to their children, but exercise their children and let them say what the topic requirements mean in their own words.
If you find that your child's understanding is incorrect and incomplete, let the child read it again and try to let the child find the requirements given by the topic.
If the child still can't understand the problem correctly after reading it several times, parents can help the child analyze it by asking questions. Commonly used questions are:
What does the topic ask us to do? (Circle, connect, color, fill in the blanks and calculate); 2 What do you need? (circle who? What kind of connection? What color? )。
For example:? Draw the same height with the same color. ? Q: Do what? (coloring); Color who? (same height); What color is it? (same color).
After the child correctly understands the meaning of the question, let him select the key words and sketch them to help him deepen his understanding and memory. The above problem can be outlined as follows: draw the same height with the same color.
The third time: read it again after a correct understanding to deepen your memory and understanding. Then start to do the problem.
Solve independently, check by yourself, and be responsible for your actions.
1, after understanding the meaning of the question, let the children answer the question themselves.
2. After answering the questions, check yourself against the requirements of the questions.
There are many methods of examination, different examination methods are not necessarily the same, but there is a general principle, that is, we should not only look at the answers, but also look at the requirements of the questions, check the process against the questions, and finally the answers. If it is a fill-in-the-blank question, the most basic trick is to see if it is smooth; This is a calculation problem. You must do it again. Parents can guide their children to choose the corresponding examination method according to the question type.
3 Three ways to correct mistakes
Children will ask their parents to check after checking themselves. If mistakes are found, parents will teach him how to correct them according to them.
1, Class A: careless error.
Parents don't give any hints after finding the mistake, but remind him to look at the topic requirements, pictures or words again, and then think about the process and answers.
If the child finds and corrects himself, let him write an A under the serial number of this question, indicating that this mistake is caused by carelessness and can be corrected by himself, and remind himself not to be careless again.
2. Class B: Method and knowledge errors.
Children don't know why they are wrong, so parents can give him a hint. For example:
Question: Which of the following lines is different? Draw it in brackets behind it? .
( 1) 1、2、3、4、5()
(2)2、4、6、8、 10()
(3)5、6、7、8、9()
Children can understand the topic and ask for different lines, but they don't know which line is different. Parents can prompt: What happened to the number in the first line? How much is it each time? In the second line, the child thinks according to the prompt, rather than the parents telling him the answer directly. In short, parents will never replace things that can make children think.
After the child follows the prompts, let him write a B under the serial number of this question, which shows that he still has some difficulties in this kind of problem. This is his own weakness and needs to think more and practice more in the future.
3. class c: incomprehensible problems.
Some wrong methods suggested by parents will not be solved in the future. Parents must explain the methods and processes to help their children make them. Please write a C under the serial number for this kind of question, indicating that this is a difficult point for children, and remind children to pay attention when the teacher explains similar problems.
4. The labeling of these symbols A, B and C is actually the reason why children analyze their mistakes, which can effectively help children find the root causes of mistakes and help them find corresponding solutions.
For example, class A errors need to be carefully read and carefully checked; For mistakes, you need to listen carefully to the methods of teachers and classmates in class, think more and practice more.
Parents can design similar topics for class B and class C mistakes to practice for their children, so as to avoid weakness and difficulties next time.
After this habit is formed, children can manage themselves at a high level of study. There are many advanced subjects, many contents and tight time, and the review is targeted. Take out the books and homework, review and consolidate the B and C classes, and you can efficiently complete the knowledge leak detection and key breakthrough, which not only saves time, but also is relaxed and happy.
4 mistakes must be corrected when they are known, and mistakes do not happen overnight.
Before you do your homework every time, correct the wrong questions you haven't changed before you can start doing new homework. Some classroom assignments done at school should be corrected on the day after the children come home if they haven't had time to correct them at school. Children often only pay attention to correcting homework and ignore other homework. Parents can remind their children to take out their homework every day to see if there are any mistakes.
Wrong questions are a burden on children. Only by removing it can we clear the obstacles for the next day's study and help children easily enter the new curriculum, which will be a virtuous circle. Otherwise, these unresolved mistakes will make it difficult to learn the new lesson the next day, and the burden on him will become heavier and heavier like a snowball, which will eventually lead to children's learning difficulties, weariness, inferiority and pain.
5. Record the time spent at work.
Write the time at the end of each assignment, for example, when you do page 9 and 10 in the workbook, write the time at the end of 10, not in the assignment notebook.
Recording time will put pressure on children, which can urge them to concentrate and concentrate on completing their homework. At the same time, in order to pursue speed, children will consciously look for effective, simple and fast solutions to problems, which is very helpful to cultivate their excellent thinking quality.
At the beginning, parents can help watch the time. It is suggested to buy a clock now, so that children can learn to recognize the clock slowly and record the time by themselves. The understanding of clocks and watches itself is a difficult point in the first grade, and it can also help children learn clocks and watches.
Focusing on efficient homework habits will play a great role after children enter junior high school and senior high school.
