"It's not a combination of three calculations, and it's not a plan. What algorithm are they doing?" Teacher Chu asked aggressively, as if he was dissatisfied with the expert's abandonment of her views.
Could it be a missing question?
By the way, did the expert collude with Teacher Ning from the Bayi Children's School?
The two education experts squeezed their eyebrows and simply handed over the task of setting the questions to Teacher Chu.
Teacher Chu took over the task and immediately increased the difficulty for the children: "Seven hundred and eighty-nine times eighty-eight eighty-eight eighty-eight, divide by twelve, subtract 4527, add 18 million eighty-nine--"
When other teachers heard Teacher Chu heading straight to the billion-dollar position, they were filled with surprise.
What does this Teacher Chu want to do? Are you planning to use the ultimate weapon to eliminate these children?
I saw that the six children in Class 3 of Year 6 were quite calm. Several of them answered slowly, but the other two children still answered quickly, almost every second: "One thousand eight hundred and fifty seventy thousand nine hundred and forty-eight."
Teacher Chu's face suddenly became silent.
Other teachers asked Teacher Chu: "Is the answer correct, Teacher Chu?"
Teacher Chu's mouth moved and said in a vague way: "It should be right."
The other teachers heard it all, the children had calculated it, but Teacher Chu himself did not calculate the answer to the question he had asked!
The teachers all had no idea about Teacher Chu.
Teacher Chu quickly defended himself: "Don't you find it strange? They answered questions much faster and slower."
"Some of them calculate faster, while others are slower. Otherwise, how can there be rankings in the competition?" Even Mr. Zhu Shiqing and others from Heping No. 1 Primary School felt that Mr. Chu's doubts were too incompetent.
"Question, how do they calculate the paper, pen and abacus without touching it? Do they rely on mental arithmetic?" Teacher Chu made continuous questions and would not admit it easily.
"Teacher Ning, tell us what's going on." The two experts also had questions about this and asked Ning Yunxi.
Ning Yunxi walked over and put his hand on the little shoulders of several children and said, "The three students here use fast mental arithmetics. The other three students use mental arithmetics."
Quick mental arithmetic?
Mental abacus?
A new noun?
On-site experts and all teachers can look at Ning Yunxi with a surprised expression of the earth.
The six children were happy first and looked at the confused expressions of the other teachers. Only Teacher Ning knew them best and saw their little secrets.
Ning Yunxi explained to the experts: "I teach their algorithms, so I know more about their level than other teachers. Quick-minded arithmetic is a pure mental arithmetic method. The mantra is different from the arithmetic, and it is easy to learn and learn from the mental arithmetic. Students with poor levels will use fast-minded arithmetic rather than the mental arithmetic to calculate the questions."
"What is mental abacus, Teacher Ning?" Teacher Zheng asked about this new algorithm that sounds like the most difficult one.
"The abacus is to form an abacus in the human brain, and to plan the abacus in the brain, and to develop the right brain function of children. Because the abacus in reality is replaced by the abacus imagined in the brain to plan the abacus, there is no need to use the abacus in reality."
"Listen to your explanation from Teacher Ning, we have a preliminary concept. This mental abacus is really not easy." Two educational experts heard the high requirements of mental abacus on students and imagined the abacus in the minds of people. Not every child can learn in a short time. Moreover, there may even be many children who cannot do it.
