Title: The "War" Caused by Children's Math Problems
Body:
"What's wrong with my child?" This phrase coming out of the mouth of a parent usually means that a "war" on education is about to break out. Recently, a parent had an interesting "debate" with his child's teacher over a math problem.
1. Parents question the wrong question
Here's the thing, the child wrote a question on his math homework at school: 9+9÷3=12. However, the teacher judged this question wrongly, and the parents were naturally not convinced. So, he took the child's homework and found the teacher aggressively.
"This question is obviously correct, why is it wrong?" Parents' voices were full of doubts.
2. The teacher patiently explains the rules
The teacher looked at the parent's appearance and explained with a smile: "This parent, you may have forgotten the rules of math. According to the principle of multiplication and division first, then addition and subtraction, the correct answer to this question is 10. ”
"9 plus 9 is 18, 18 divided by 3 is 6, and finally 9 is added, and the answer is 15. So, 9+9÷3 is not equal to 12, but equal to 15. The teacher patiently explained.
3. Parents move out of the "authority" theory
After hearing this, the parents still did not give up: "However, I saw a statement on the Internet that the rules of mathematics can be used flexibly. It's not wrong to write this question as 9+9÷3=12! ”
The teacher couldn't laugh or cry, but he didn't expect the parents to come up with the "authority" theory.
4. The teacher skillfully demonstrates the problem solving
In order to completely dispel the doubts of parents, the teacher picked up the chalk and skillfully demonstrated the problem-solving process on the blackboard. As he wrote, he explained: "You see, 9÷3 equals 3, and then 9 plus 3 equals 12, and that's according to the rules of mathematics. ”
"And if you do it according to 9+9÷3=12, you actually violate the basic rules of mathematics. This kind of calculation will cause big problems in the child's future learning process. ”
5. Parents are dumbfounded
Parents looked at the clear problem-solving process on the blackboard, and were speechless for a while. He originally thought that he had found the teacher's "loophole", but he didn't expect to be taught a vivid math lesson by the teacher instead.
6. The audience ended hilariously
This "debate" ended with the embarrassment of the parents and the laughter of the audience. The parents left the classroom with a red face, secretly vowing in their hearts that they must pay more attention to their children's learning in the future and not make such jokes again.
Although this incident is hilarious, it also reminds us that when educating children, we must respect the laws of education and do not blindly believe in the "authoritative" theories on the Internet. At the same time, it is also necessary to educate children and abide by the rules in order to go further and further on the road of learning.
