北师大初中数学八年级上册二次根式的混合运算2教案
本节课开始时，首先由一个要在一块长方形木板上截出两块面积不等的正方形，引导学生得出两个二次根式求和的运算。从而提出问题：如何进行二次根式的加减运算?这样通过问题指向本课研究的重点，激发学生的学习兴趣和强烈的求知欲望。本节课是二次根式加减法，目的是探索二次根式加减法运算法则，在设计本课时教案时，着重从以下几点考虑：1.先通过对实际问题的解决来引入二次根式的加减运算，再由学生自主讨论并总结二次根式的加减运算法则。2.四人小组探索、发现、解决问题，培养学生用数学方法解决实际问题的能力。3.对法则的教学与整式的加减比较学习。在理解、掌握和运用二次根式的加减法运算法则的学习过程中，渗透了分析、概括、类比等数学思想方法，提高学生的思维品质和兴趣。
北师大初中数学八年级上册二次根式的运算2教案
1．关于二次根式的概念，要注意以下几点：（1）从形式上看，二次根式是以根号“ ”表示的代数式，这里的开方运算是最后一步运算。如 ， 等不是二次根式，而是含有二次根式的代数式或二次根式的运算；（2）当一个二次根式前面乘有一个有理数或有理式（整式或分式）时，虽然最后运算不是开方而是乘法，但为了方便起见，我们把它看作一个整体仍叫做二次根式，而前面与其相乘的有理数或有理式就叫做二次根式的系数；（3）二次根式的被开方数，可以是某个确定的非负实数，也可以是某个代数式表示的数，但其中所含字母的取值必须使得该代数式的值为非负实数；（4）像“ ， ”等虽然可以进行开方运算，但它们仍属于二次根式。2．二次根式的主要性质（1） ； （2） ； （3） ；（4）积的算术平方根的性质： ；（5）商的算术平方根的性质： ；
