There is obviously no superclass in the question, and the calculation is not complicated, but the entanglement in the question especially tests the understanding ability, and you will fall into the trap of the question if you are not careful!
3600÷9=400 was scratched! "What happened to my son?"
Not long ago, a treasure mother asked the teacher in class if she had made a mistake.
She looked at her son's paper and found that the calculation process of a topic was 3600÷9=400. There is nothing wrong with the calculation, but the teacher made a cross!
The question is this:
The music store bought nine new violins and spent 3600 yuan. The reasonable price is () A498 Yuan/B400 Yuan/C498 Yuan/D400 Yuan/piece.
His son chose option D according to the above calculation process.
However, the teacher explained that the calculation result of 400 yuan/Ba was the purchase price of violin. This question asked about the reasonable selling price, which should be higher than the purchase price, so it should be A..
After listening to the teacher's explanation, parents realized that they didn't look at the topic as seriously as children and made a joke!
Bao Ma, who was slapped in the face, quickly apologized to the teacher.
However, I have to say that the math problems of primary school students now really test their understanding ability. My son often loses points because he can't understand the problems and the deviations!
It is really important to pay attention to children's reading ability!
How to help children improve their reading ability?
1, teach children common sense of life
Most math application problems in primary schools are based on life scenes, and some math knowledge is added.
The most common topics are buying and selling goods, getting on and off the bus, planting trees and flowers.
These topics probably hide some common sense of life. If children don't know, they will suffer!
Like this topic of laying rails, although it is not mentioned in the title, according to common sense, there are two rails, so divide 10 by 2.
2. The combination of mathematics and games
In addition to common sense, children need to improve their ability to understand languages. Words like "more", "more" and "not less than" can easily confuse children.
There is no shortcut to help children avoid falling into the trap of problems. You can only use and listen to these words more to help children understand.
Parents can use games to attract children to increase their exposure to mathematical vocabulary in their lives and enhance their understanding of mathematical vocabulary in play.
Step 3 read the questions carefully
Careful examination of questions is simple to say, but it is the most important ability.
Many children's own abilities and knowledge are not bad, but when they look at the questions, they are careless and lose points in vain!
My son's deskmate is very clever, but he always loses points because he doesn't look at the questions carefully in every exam, and he misses the words "How many are left" and "How many more are needed"!
Parents should teach their children that when reading a topic, they can point to it, read it word by word, and pay attention to the details!
