谈整式学习的要点
整式是代数式中最基本的式子,引进整式是实际的需要,也是学习后续内容（例如分式、一元二次方程等）的需要.整式是在以前学习了有理数运算、列简单的代数式、一元一次方程及不等式的基础上引进的.事实上,整式的有关内容在六年级已经学习过,但现在的整式内容比过去更加强了应用,增加了实际应用的背景.
本章有较多的知识点属于重点或难点,既是重点又是难点的内容为如下三个方面.
一、整式的四则运算
1.整式的加减
合并同类项是重点,也是难点.合并同类项时要注意以下三点：①要掌握同类项的概念,会辨别同类项,并准确地掌握判断同类项的两条标准��字母和字母指数；②明确合并同类项的含义是把多项式中的同类项合并成一项,经过合并同类项,多项式的项数会减少,达到化简多项式的目的；③“合并”是指同类项的系数的相加,并把得到的结果作为新的系数,要保持同类项的字母和字母的指数不变.
2.整式的乘除
重点是整式的乘除,尤其是其中的乘法公式.乘法公式的结构特征以及公式中的字母的广泛含义,学生不易掌握.因此,乘法公式的灵活运用是难点,添括号（或去括号）时,括号中符号的处理是另一个难点.添括号（或去括号）是对多项式的变形,要根据添括号（或去括号）的法则进行.在整式的乘除中,单项式的乘除是关键,这是因为,一般多项式的乘除都要“转化”为单项式的乘除.
整式四则运算的主要题型有：
（1）单项式的四则运算
此类题目多以选择题和应用题的形式出现,其特点是考查单项式的四则运算.
（2）单项式与多项式的运算
此类题目多以解答题的形式出现,技巧性强,其特点为考查单项式与多项式的四则运算.
（3）多项式与多项式的运算.
此类题目多以填空题和解答题的形式出现,其特点为考查多项式的四则运算,技巧性也较强.
二、因式分解
难点是因式分解的两种基本方法.因式分解是整式乘法的逆向变形,因式分解的方法的引入要紧紧抓住这一点.
三、利用好选学内容
“阅读与思考”和“观察与猜想”是课本上的两个选学栏目,其内容是有关知识的拓展与延伸.“杨辉三角”不但可以使同学们了解一些二项展开式中各项系数的规律,增强数学修养,还可以潜移默化地培养同学们的爱国情怀.
数式化简求值题归类及解法
代数式化简求值是初中数学教学的一个重点和难点内容.学生在解题时如果找不准解决问题的切入点、方法选取不当,往往事倍功半.如何提高学习效率,顺利渡过难关,笔者就这一问题,进行了归类总结并探讨其解法,供同学们参考.
一.已知条件不化简,所给代数式化简
二.已知条件化简,所给代数式不化简
三.已知条件和所给代数式都要化简
