华罗庚既是一位中外著名的数学大师,又是一位教育家,他不仅关心高等教育,也非常热心于青少年的培养。下面就简单介绍几个与华教授数学思想方法有关的问题。一、华罗庚与直接法华罗庚曾给小学生出过一道数学题:假如我们家里有九口人,每人每天吃半两油。问:一个月要用多少斤油?(旧制16两为1斤)孩子们用树枝在地上列式子,一个孩子是这样计算的:0.5×30×9÷16,华罗庚说:“这样算当然可以,但是还有更简便的方法。”孩子们天真地看着华老,他扳着手指说:“每人每天半两油,每人每月就是15两,全家就是九斤差九两,也就是八斤
Hua Luogeng is not only a famous Chinese math math teacher, but also an educator, he not only concerned about higher education, but also very enthusiastic about the training of young people. Here is a brief introduction to several issues related to Professor Hua’s mathematical thinking. First, Hua Luogeng and direct law Hualang Geng had given pupils a math problem: If we have nine people at home, eat half a day two oil each person. Q: How many pounds a month to use oil? (Old 16 two for 1 kg) Children with branches on the ground column type, a child is calculated: 0.5 × 30 × 9 ÷ 16, Hua Loge said: ” Of course, but there is a more convenient way. “” The children naive looked at the Chinese, he wrenched his fingers and said: "Half a day two people per person per person per month is 15 two, the whole family is nine pounds worse Nine two, that is, eight pounds
