Reflections on the examination paper of mathematics unit
The last paper was handed down, and I couldn't calm down for a while. Finally sent it to me. I opened it and was surprised! There is a big red 90 on the test paper.
Looking down again, I saw a red cross at a glance: 6 thousand () 600 () filled in, and I filled in 6 thousand () 600; The correct solution is: let them unify their units before they can compare, so the question should be:
10 100 is 1000, so 60 100 is 6000, which is six thousand. In this case, they should be equal and the brackets should be filled with an equal sign. I was wrong about this question because I didn't see the unit clearly. I can't make this mistake again next time.
The second fork is: () ten-three hundred; I wrote (1) ten to three hundred. Hey, 10 is100; My 1 10 is more than 300, which is really sloppy! The correct one should be (40) ten to three hundred. This problem is the same as the last one, but the mistake is that it has not been carefully looked at and there is no unified unit.
There are three graphic problems: one is to give a graph composed of several graphs, so that you can count how many graphs there are. Actually, I'm good at this, but I'm still wrong. The main reason is that I didn't mark the counted maps and repeated them too much. Next time you do it, you must be diligent, count one conveniently and mark one, so that you won't make mistakes again. The other one is for Lin Qiang.
Three squares with a side length of 3 ㎝ make up a big square. What is the side length of this big square? My answer is 3 ×9=27㎝, and the correct answer should be 3× 3 = 9 ㎝; After reading this question, I knew it was 9 ㎝, but it was written as 3×9=27㎝. Another problem is that I didn't draw a plane quadrilateral according to the grid.
After reading these wrong questions, I can do everything right as long as I put my heart into it. I will do it carefully in the next exam. I will read the exercises several times and do them after I understand the meaning of the questions. After writing the paper, you must check it carefully, get rid of your bad habit of being sloppy, and strive for a good grade in the exam.
