a more than 50 person British expedition to Ningbo to communicate in Ningbo. They are the principal and teaching directors of the top 25 primary and secondary schools in Britain. They were divided into 5 groups, listening to mathematics classes in several schools in Ningbo.
yesterday, the 25 members of the delegation went to Ningbo Wanli international school and Ningbo high tech Zone Foreign Language School.
a British headmaster said that Chinese children's mathematical ability is well known in the world. They often wonder why the Chinese children always take the first place in international competitions in mathematics. They came to China to learn the teaching method of Chinese mathematics.
yesterday morning to the afternoon, they listened to 4 math classes, and the results, the math 99 multiplication formula and the Chinese students' mathematical abilities, gave them a deep shock.
the whole course of the class, the British teachers were standing in the
math class yesterday, and the chairs of the English teachers were all empty behind the class - they walked into the middle of the students, looked at the students' textbooks, the exercises, and filmed with a cell phone and a camera. Chinese children did not disappoint them, too.
a grade three math class in Ningbo Wanli international school primary school, the teacher wrote a topic on the blackboard:
72, 3 =?
a classmate comes up and writes the answer 24 at once. The student said that using the "99 multiplication formula" can quickly come to a conclusion. The 12 British teachers at the scene were suddenly surprised.
an English teacher said that there is no such formula in England, 72, 3 =? The question is:
10 x 3 = 30, 10 x 3 = 30, 4 x 3 = 12, and then superimposed, the answer is 24.
this problem can be learned in several classes in Britain.
is it too difficult for Chinese children to learn Chinese education? An English teacher said that he did not think so, but that the standard of mathematics teaching in England was too low.
wanted to learn the 99 multiplication formula but failed. The reason is that when English pronunciation is not fluent in
the English teacher wants to learn the 99 multiplication formula when communicating with the teacher of Ningbo.
Mr. Zheng, director of the primary school of Ningbo Wanli international school, said that the 99 multiplication formula is the traditional Chinese method, but the English teachers are hard to learn, because English pronunciation restricts the recitation of the pithy formula.
99 multiplication pithy formula in Chinese five words, and at a glance, and in English is a very long period, such as "99 eighty-one", English is "nine nine eighty one".
learn not to learn, no gain. After returning home, the British teachers said they would form a document and submit it to the British Ministry of education, hoping to help the British primary and secondary school mathematics education.
