Why do I have to make a rough draft of my math calculations?

Question 1: Original = 1 3-1 4+1 4-1 5+1 5-·· 1 98-1 99

Question 2: Original =

Question 3: Original =

Question 4: Original = 4*

Question 5: Original =

Question 6: Original =

Explanation: 1 question. After trying, it can be found that 1 (3*4)=1 3-1 4, and so on and so on.

2 to 6: The idea is the same, find a least common divisor, and then bring this number forward, most of the numbers in parentheses are like this, OK.

Sorry, it's so hard to find, there are only 9 here.

Who's weight, this has to weigh much!!

Habit... Then you don't have a solid foundation.

I'm all in faith, generally 150, high school.

If your child's math scores are not improving because of carelessness, then pay attention to whether he is doing a good job of drafting.

When writing homework, it is necessary to pay attention to the early draft, so that some careless calculation mistakes can be effectively avoided.

In addition, you also need to pay attention to the neatness of the draft, the draft book is messed up, and when you check the work, you will be like a headless fly, and you will not find the direction.

In fact, there is also learning in drafting. And the secret of the school's draft is not only neatness, but also various details.

1.Write a row of numbers on a line.

There's no need to save when you're making drafts, and don't use them with a smile.

Don't overfill or crowd the numbers, make the layout of the scratch paper clearer, and it will be easy to check.

2.Make good use of dividers.

After each question is drafted, use a divider to separate the two questions, so as not to make the draft content of the two questions too close to each other, so as to avoid the low-level hail mistake of copying the answers of question A to the area of question B.

3.Mark the question number.

Mark the question number on the scratch paper, which is a sketch trick that only top students can use.

Marking the question number makes it easier to locate the location of each question and makes it easier to find.

4.Drafts must not be drafted.

Please also pay attention to the handwriting when typing the draft, and do not scribble it so much that you can't even read it yourself.

Today, I proctored math.

Halfway through the exam, some of my classmates asked me for scratch paper. I think it's strange that the school issued an A4 piece of paper, isn't it enough to make a draft? I found a piece of paper and handed it to him, and then I looked around the classroom and noticed that the vertical types were lying on the scratch paper, most of them scribbling themselves, and I saw that the students were writing rapidly on the scratch paper.

I know that students think it's a draft, so why take it so seriously! Actually, that's not right. As everyone knows, it is really because children write in such a hurry that they are easy to copy the wrong number and regard 6 as 0

The decimal point is ignored and it is easy to make mistakes.

Suggestion: Make a serious draft and write a good question number.

Do your homework as you normally would.

Neatly arranged and neatly written.

In this way, it is not easy to copy the wrong numbers and read the wrong numbers; It is also beneficial to use this vertical type again during the examination, which means that it saves the time of the examination and improves the accuracy of the calculation. Furthermore, as a result of passing a period of revision, students will not feel that the final exam papers are difficult, or even easier than usual; And there is more time for the exam than usual.

Think: The teacher should tell the students how to develop a good habit of making drafts; Don't be in such a hurry, just finish the paper step by step carefully, and it is best to get it right the first time.

Hello! We're happy to answer for you!

Answer: Draft canonical format:

1) The writing should be standardized and orderly, and it should be written as carefully as the homework, and not sloppy writing just because it is a draft book, otherwise it will bring a lot of unnecessary mistakes.

2) There should be partitions or dividing lines on the scratch paper, and sometimes the draft content of the two questions is too close to each other, so it is necessary to use the dividing line to separate the draft content between the questions, so as not to copy the process of question A to the answer area of question B when answering on the test paper;

3) Drawing should still be used as a drawing tool, but the speed should be a little faster, not to strive for excellence, but it should not affect the question, after all, the exam time is precious;

4) During the exam, if you encounter a question that you are not sure of, you should indicate the inspection link, so as to facilitate the final check and fill in the gaps;

5) Mark the question number, whether it is usually doing math homework or a formal exam, mark the question number on the draft, and locate the position on the draft paper through the question number, which is clear at a glance and easy to find quickly;

6) Here is a special point to mention, don't write too full of scratch paper, to make the draft paper layout clear, some students in the draft "too saving", use the sketch book at every turn, resulting in the whole scratch paper full, looks plump, in fact, it looks very head-catching, to say an exaggeration, want to find a certain topic from the scratch paper of the draft process is a bit of a needle in a haystack embarrassment.

Therefore, it is important to make drafts in order, and some students like to pick blank spaces when they are drafting, so that there are drafts in all directions, so that's all"Grass"Nope"Draft"I can't find it after a while, and I can't do it with such a draft in the exam.

7) The calculation steps, outlines, and ideas are basically complete, and the process is roughly standardized. Why"Basic"、"Roughly"That's what drafts do. Calculate the skip step, and if it's wrong for a while, you still can't find the problem, and you can't check it.

Incomplete drafts, as well as none; If it's too detailed, it doesn't need to.
