乘法分配律是小学数学的一个教学重点和难点,其数理抽象,逻辑严密,尤以“难”字突出。如何使学生更容易接受这部分知识?通过多年的教学实践,我摸索出了一些教学乘法分配律的有效方法,并取得了良好的教学效果。生活体验法。《数学课程标准》指出:“数学教学体现生活性,人人学有价值的数学。”在课堂教学活动中,教师要创设数学教学情境,重视数学知识生活化,强化在生活实践中的应用。这样既可以加深对知识的理解,又能 The law of multiplication distribution is a key and difficult point in elementary mathematics teaching. Its mathematical and abstract logic is rigorous, especially in terms of “difficult”. How to make students more easily accept this part of knowledge? Through many years of teaching practice, I worked out some effective method of teaching multiplication law, and achieved good teaching results. Life experience method. “Mathematical Curriculum Standard” states: “Mathematics teaching embodies the value of life, all human learning mathematics.” In the classroom teaching activities, teachers should create mathematical teaching situations, emphasis on the mathematical knowledge of life, and strengthen the life practice application. This will not only deepen the understanding of knowledge, but also
