一、复习算术的目的初中一年級在学习代数之前,安排有一段时間复习算术,其目的主要有以下三点: 1.通过算术复习課,使学生对已学过的算术知識得到有系統、有重点的复习巩固机会,加深他們对算术基础知識的认識;补充他們在小学未学过的算术知識,使学生对算术知識有个比較完整的概念;培养他們对算术各种运算的技能与技巧,并通过将来不断地实践,逐漸具有灵活运用的本領。 2.通过这次复习对过去中学生在中学数学課程中,經常出現的有关算术运算的錯誤,有意識地預先加以防犯。 3.通过算术复习課,尽可能把他們已学会的算术知識,有計划地、有机地与以后代数知識的学习联系起来,为将来学好代数知識創造有利条件。
First, review the purpose of arithmetic The first grade of junior high school to arrange for a period of time to review the arithmetic before learning algebra, its purpose is mainly the following three points: 1. Through the arithmetic review class, so that students have a systematic knowledge of arithmetic knowledge has been learned, Focus on reviewing and consolidating opportunities to deepen their understanding of the basics of arithmetic; to supplement their knowledge of arithmetic that they have not learned in elementary schools, so that students have a more complete concept of arithmetic knowledge; to develop their skills in various arithmetic operations and Skills, and through continuous practice in the future, gradually have the ability to use flexibly. 2. Through this review, consciously anticipate the past mistakes in mathematics operations that have occurred frequently in middle school students’ mathematics courses in middle school. 3. Through mathematics review classes, as far as possible, they have learned the arithmetic knowledge that they have learned systematically and organically, and they have learned to link with later algebraic knowledge to create favorable conditions for learning algebraic knowledge in the future.
