1教学目标(1)了解同底数幂乘法的运算法则,并能正确地运用法则解决一些实际问题。(2)能够在情境中抽象概括出所要研究的数学问题,增强学生的数感、符号感,经历探索同底数幂乘法运算法则的过程,进一步体会幂的意义,发展推理能力和有条理的表达能力。(3)通过同底数幂乘法法则的推导和应用,使学生初步理解“特殊—一般—特殊”的认知规律,体会类比、转化、归纳等数学思想方法,激发学生探索创新精神。感受数学与现实生活的密切联系,增强学生的数
1 teaching objectives (1) to understand the same floor power multiplication algorithm, and can correctly use the law to solve some practical problems. (2) Abstracted in the context of the mathematical problems to be studied, to enhance students sense of number, sense of symbol, through the process of exploring the principle of multiplication with the base power, to further understand the power of meaning, the development of reasoning ability and structured expression ability. (3) Through the deduction and application of multiplicative law of the same base, students can understand the cognitive law of “special - general - special ” and understand mathematical thinking and methods such as analogy, transformation and induction to stimulate students to explore innovative spirit. Feel the close connection between mathematics and real life, enhance the number of students
