笔者试图为搞好初中数学各年级各学期的期末复习提供一套较为完整的备课资料,以帮助教师在不增加复习时数和不加重学生负担的前提下,提高复习课的教学质量。本文是各年级上学期的期末复习设计。文中如有错误或不当之处,恳请教师们批评指正。初一代数(初中《代数》第一册,约复习6课时)§1 有理数复习要求及方法复习要求:巩固正、负数,相反数,倒数,数轴和绝对值的概念,正确熟练地运用有理数的运算律及运算法则进行四则运算。复习方法:对有理数的有关概念,可通过课堂提问和举例来加以巩固和深化;对有理数的四则运算,可通过分析它与算术四则运算的联系和区别,重点复习好有理数运算的符号法则。
The author attempts to provide a complete set of preparation materials for completing the final review of each semester of junior high school mathematics so as to help teachers improve the teaching quality of the reviewing class without increasing the number of reviewing hours and increasing the students' burden. This article is the final semester of the grade review design. In the text, if there are mistakes or improper, teachers are urged to criticize. The first generation of algebra (junior high school Algebra Volume I, about 6 hours of review) §1 Rational Number review requirements and methods Review requirements: Consolidation of positive, negative, opposite, reciprocal, axis and absolute value of the concept of the correct and skilled use of rational numbers Algorithm and algorithm for four operations. Review method: The concept of rational numbers can be consolidated and deepened through questions and examples in the classroom. For the four operations of rational numbers, we can analyze the relation and difference between them and arithmetic operations, and review the symbolic rules of rational numbers operations.
