Math teachers should pay attention to writing norms when commenting. In the study of mathematics, calculation ability and logical thinking ability are often emphasized, while writing generally requires neatness, and the beauty of writing will not be overemphasized. However, some children often lose points because of writing when they finish their math homework or take exams.

In normal study, you will also meet such children. When he calculated continuously, the answer was correct, but the written 6 was too similar to 0, so he conveniently wrote the answer as 0, so he wouldn't get the score of this question. What's more, the written handwriting is too difficult to identify, so let the students identify it themselves. He read it for a long time and didn't know what he was writing.

Of course, only a few students can't write clearly, but when doing homework, pay attention to the format, make the writing standard and the paper neat, which can effectively avoid some points lost due to careless writing.

Pay attention to the norms of writing in the usual work, such as:

1. The calculation questions and copy questions should be copied completely (including the requirements of the questions). When copying questions, write the distance from the empty words (about half a centimeter, the length of an equal sign) according to the requirements of the questions.

2. Calculation problem: Write an equal sign directly by one-step calculation. If you want to list the vertical style, you should write it in the middle of the horizontal style. If there are more than two steps, the recursive equation should be aligned with the equal sign, and the length is about half a centimeter.

3. After copying the title, start another determinant, with a digression of about half a centimeter. The calculation is based on the above requirements.

4. After completing one question, do the next question in blank, including different small questions of the same question.

5. When writing words or numbers, the size should be moderate, the number "5" should not be combined into "8", and "0" should not be confused with "6".

6. In principle, the vertical checking calculation is side by side with the vertical checking calculation, and the word "checking calculation" is written in the middle of the two types. If the vertical style space is not enough, you can't cut off the whole formula, but change it to the next column as a whole.

7. When solving the equation, the position of the word "solution" is left blank, and the word "solution:" is written on the left side of the second line, and the equal sign is aligned up and down.

8. To solve practical problems with column equations, you should first write the word "solution" and define the sentence, and you don't need to write the unit name after the last number.
