《数学课程标准》明确提出:“数学教学要求联系学生生活,从学生已有的知识和生活经验出发,创设各种情境,为学生提供从事数学活动的机会”。在实际情境下进行教学,可以使学生利用原有知识和经验同化当前要学习的新知识,这样获取的新知识,不但便于保持,而且容易创新。创设教学情境,不仅能使学生容易掌握数学知识和技能,而且能使学生更好地体验数学内容中的情感,使原来枯燥的、抽象的数学变得生动形象。在教学乘数末尾或中间有零的乘法计算时,对于三年级
The standard of mathematics curriculum clearly states: “Mathematics teaching requires contacting student life, starting from the student’s existing knowledge and life experience, creating various situations and providing students with opportunities for conducting mathematical activities.” Teaching in a real situation enables students to assimilate the new knowledge they are currently learning based on their original knowledge and experience so that the new knowledge gained is not only easy to maintain but also easy to innovate. The creation of teaching situations not only enables students to master math knowledge and skills easily, but also enables students to better experience the emotions in mathematics content so that the original boring and abstract maths become vivid. At the end of the teaching multiplier or in the middle there is a zero multiplication calculation, for third grade
