初中的数学课程,尤其是初中一年级的数学课的教学是由小学的数的运算逐步过渡到代数式、方程及不等式的全过程教学。因此,做好从小学到初一数学知识的衔接是十分必要的。让知识的系统性与循序渐进性相结合,使学生逐步适应中学阶段的学习,是初中教学特别是初一教学的基本要求。 The mathematics curriculum of junior middle school, especially the mathematics teaching of the first grade junior high school, is gradually transitioning from the operation of the elementary school to the algebraic equations, equations and inequalities. Therefore, it is necessary to do a good job of connecting mathematics knowledge from primary school to the first day. The combination of the systematic nature of the knowledge and the gradual and orderly progress makes it possible for students to gradually adapt to the learning at the middle school level. This is the basic requirement for junior middle school teaching, especially for the first-year teaching.
