教学内容:人教版小学数学五年级上册第四单元“可能性”。教学背景分析:(一)教学内容。“可能性”是指事物发生的概率,是包含在事物之中并预示着事物发展趋势的量化指标。概率又称或然率、机会率或机率,是一个在“0”至“1”之间的实数,是对随机事件发生的可能性的度量,是事件本身所固有的不随人的主观意愿而改变的一种属性,是数学学科中概率论的基本概念之一,而概率论正是研究不确定现象的规律的数学分支。自然现象和社会现象纷繁多样,但从结果能否被
Teaching content: PEP 5 elementary school fourth unit “possibility ”. Teaching background analysis: (a) teaching content. “Possibility ” refers to the probability of something happening, which is a quantitative indicator that is included in things and indicates the trend of things. Probability, also known as probability, chance or probability, is a real number between “0 ” and “1 ”, a measure of the likelihood of a random event occurring, an inherent non-consensual subjective One of the attributes of change in will is one of the basic concepts of probability theory in mathematics, and probability theory is just a mathematical branch of the law of uncertainty. Natural phenomena and social phenomena are numerous and varied, but whether the result can be
