孤儿缺乏关键的早期家庭教育,所以对生活中存在的数学知识缺乏敏感度,对一些数学常识甚至不知道,不了解。所以,作为一名特殊教育的初中数学教师,在课堂上更要费尽心思去解释或去演示一些生活中常见的数学知识。以下举一些课堂中常见的例子:对于阶梯式收费的详细解释例题:吉林省为促进居民节约用水,试行阶梯式水价,具体办法是:以每户每月用水量为计价依据,试行三级阶梯水价:用水量不超过4立方米,每立方米按1.5元计费;超过4立方米,
Orphans lack critical early home education, so they lack sensitivity to the mathematical knowledge that exists in their lives and do not even know or understand some of the mathematical common sense. Therefore, as a special education junior high school mathematics teacher, in the classroom more painstakingly to explain or to demonstrate some of the common mathematical knowledge in life. Here are some common examples in the classroom: A detailed explanation of the ladder charges Example: Jilin Province to promote residents to save water, try the ladder of water prices, the specific measures are: monthly water consumption per household as a basis for pricing trial of three steps Water price: water consumption does not exceed 4 cubic meters, 1.5 yuan per cubic meter billing; more than 4 cubic meters,
