Children's bad habits when doing homework

Phenomenon 1: Not knowing how to hurry: slow movements

Many children like to procrastinate when doing their homework. They always wait until 8:30 in the evening, or even after 9 o'clock. This is the case when they are in school, and they like to procrastinate even more during the holidays.

I often say I will write it tomorrow, but when tomorrow comes, I don’t want to write it anymore and put it off until a few days before school starts, when I start working day and night.

The child’s little thought: The holiday is so long, I can play for a few days first and then write. It’s still enough time! At worst, I can write more in the last few days.

Phenomenon: Lack of concentration

I finally made up my mind to write, but my mind was not on the homework at all. I could only persist for 15-20 minutes at most, and then I would go out to get a glass of water or go to the toilet. When there were guests at home, I had to go out to see them, or I would put my phone next to me and take a selfie to post on WeChat Moments... I had no concept of time at all, and the homework that could be completed in 2 hours was dragged to 5 hours.

The child's thoughts: Homework is so boring and annoying. I will finish this question, play some games, and then continue. This will give me motivation.

Phenomenon 3: It is difficult to balance quality and quantity: answering questions without paying attention

Normally, when doing homework, children dare not neglect it, because if they do not do well, they will be criticized by the teacher the next day. But it is different in summer vacation. The teacher will not monitor the quality of your homework every day, so the children answer questions very irregularly: they do not write the question number; they do not write "solution" for math word problems, and they do not write "answer" after drawing conclusions; the format is chaotic, and the problem-solving process is as flamboyant as the calculations on the draft paper.

Some children are seriously dependent on erasers or correction fluid. They will erase and rewrite the work if there is even the slightest flaw. This is not only inefficient, but also makes the writing untidy.

How do parents teach their children to do homework?

Regarding homework, you must tell your children that everyone has homework, and it is not that teachers and parents deliberately target you. So, don't complain, don't feel unfair, anyway, whether you learn more or less is your own. No matter what, you always have to finish it. Finish it on time every day and then play with confidence or do everything possible to delay it until the end, and think about homework while playing. It all depends on your choice. Homework is like this. When it is difficult for you, it is also difficult for others. When it is simple for you, it is also simple for others. But not everyone can think comprehensively and carefully, and this is the gap. Every question you have done, as long as you think carefully, is your new knowledge and experience. Just like life, everything you have experienced is your unique wealth!
