  • 北师大初中八年级数学下册不等关系教案

    A.20x-55≥350 B.20x+55≥350C.20x-55≤350 D.20x+55≤350解析:此题中的不等关系:现在已存有55元,计划从现在起以后每个月节省20元.若此学生平板电脑至少需要350元.列出不等式20x+55≥350.故选B.方法总结:用不等式表示数量关系时,要找准题中表示不等关系的两个量,并用代数式表示;正确理解题中的关键词,如负数、非负数、正数、大于、不大于、小于、不小于、不足、不超过、至少、至多等的含义.三、板书设计1.不等式的概念2.列不等式(1)找准题目中不等关系的两个量,并且用代数式表示;(2)正确理解题目中的关键词语的确切含义;(3)用与题意符合的不等号将表示不等关系的两个量的代数式连接起来;(4)要正确理解常见不等式基本语言的含义.本节课通过实际问题引入不等式,并用不等式表示数量关系.要注意常用的关键词的含义:负数、非负数、正数、大于、不大于、小于、不小于、不足、不超过,这些关键词中如果含有“不”“非”等文字,一般应包括“=”,这也是学生容易出错的地方.

  • 北师大初中八年级数学下册角平分线教案

    解:(1)∵AB、CD互相垂直平分,∴OC=OD,AO=OB,且AC=BC=AD=BD;(2)OE=OF,理由如下:在△AOC和△AOD中,∵AC=AD,OC=OD,AO=AO,∴△AOC≌△AOD(SSS),∴∠CAO=∠DAO.又∵OE⊥AC,OF⊥AD,∴OE=OF.方法总结:本题是线段垂直平分线的性质和角平分线的性质的综合,掌握它们的适用条件和表示方法是解题的关键.三、板书设计1.角平分线的性质定理角平分线上的点到这个角的两边的距离相等.2.角平分线的判定定理在一个角的内部,到角的两边距离相等的点在这个角的平分线上.本节课由于采用了动手操作以及讨论交流等教学方法,从而有效地增强了学生对角以及角平分线的性质的感性认识,提高了学生对新知识的理解与感悟,因而本节课的教学效果较好,学生对所学的新知识掌握较好,达到了教学的目的.不足之处是少数学生在性质的运用上还存在问题,需要在今后的教学与作业中进一步的加强巩固和训练.

  • 北师大初中八年级数学下册平方差公式教案

    答:所有阴影部分的面积和是5050cm2.方法总结:首先应找出图形中哪些部分发生了变化,是按照什么规律变化的,通过分析找到各部分的变化规律后直接利用规律求解.探寻规律要认真观察、仔细思考,善用联想来解决这类问题.三、板书设计1.平方差公式:a2-b2=(a+b)(a-b);2.平方差公式的特点:能够运用平方差公式分解因式的多项式必须是二项式,两项都能写成平方的形式,且符号相反.运用平方差公式因式分解,首先应注意每个公式的特征.分析多项式的次数和项数,然后再确定公式.如果多项式是二项式,通常考虑应用平方差公式;如果多项式中有公因式可提,应先提取公因式,而且还要“提”得彻底,最后应注意两点:一是每个因式要化简,二是分解因式时,每个因式都要分解彻底.

  • 北师大初中八年级数学下册因式分解教案

    解:设另一个因式为2x2-mx-k3,∴(x-3)(2x2-mx-k3)=2x3-5x2-6x+k,2x3-mx2-k3x-6x2+3mx+k=2x3-5x2-6x+k,2x3-(m+6)x2-(k3-3m)x+k=2x3-5x2-6x+k,∴m+6=5,k3-3m=6,解得m=-1,k=9,∴k=9,∴另一个因式为2x2+x-3.方法总结:因为整式的乘法和分解因式互为逆运算,所以分解因式后的两个因式的乘积一定等于原来的多项式.三、板书设计1.因式分解的概念把一个多项式转化成几个整式的积的形式,这种变形叫做因式分解.2.因式分解与整式乘法的关系因式分解是整式乘法的逆运算.本课是通过对比整式乘法的学习,引导学生探究因式分解和整式乘法的联系,通过对比学习加深对新知识的理解.教学时采用新课探究的形式,鼓励学生参与到课堂教学中,以兴趣带动学习,提高课堂学习效率.
