这两节课是人教版小学数学三年级上册第八单元的内容。在现实世界中,严格确定性的现象十分有限,不确定性现象却是大量存在的,而概念论正是研究不确定性的规律的数学分支。“可能性”作为义务教育数学课程的四个学习领域之一“统计与概率”中的一部分,从第一学段起就安排了有关的学习内容。主要的教学目标是使学生初步体验事件发生的确定性和不确定性;使学生学会列出简单试验所有可能发生的结果;使学生知道事件发生的可能性大小是不同的,能对一些简单事件发生的可
These two classes are the content of the eighth unit of the third grade of the PEP in PEP. In the real world, the phenomenon of strict certainty is very limited, while the phenomenon of uncertainty exists in large numbers. Conceptualism is precisely the mathematical branch that studies the law of uncertainty. “Possibilities ” As part of the “Statistics and Probabilities” one of the four areas of study in compulsory education math courses, the relevant learning content has been arranged since the first semester. The main teaching goal is to enable students to initially experience the certainty and uncertainty of events; to enable students to learn all the possible outcomes of simple experiments; to make students aware of the different possibilities of occurrence of events, What happened
