When itcomes to a meaningful life, we might think of love, happiness and health. Alife filled with meaning is what most of us want for ourselves. Then, whatmakes a meaningful life?Manyresearchers agree that a meaningful life comes down to three factors (因素): havinglong-term goals, believing that one’s life matters, and feeling that one’s lifefits together and “makes sense”.But we believe there is more to consider. Sometimeslife enables us to experience small moments of beauty. When people are open toappreciating (欣赏) suchexperiences, these moments may improve how they see their own life. We callthis experiential appreciation (EA).
北师大初中七年级数学下册单项式除以单项式教案
光的速度约为3×108米/秒，一颗人造地球卫星的速度是8×103米/秒，则光的速度是这颗人造地球卫星速度的多少倍？解析：要求光速是人造地球卫星的速度的倍数，用光速除以人造地球卫星的速度，可转化为单项式相除问题．解：(3×108)÷(8×103)＝(3÷8)·(108÷103)＝3.75×104.答：光速是这颗人造地球卫星速度的3.75×104倍．方法总结：解整式除法的实际应用题时，应分清何为除式，何为被除式，然后应当单项式除以单项式法则计算．三、板书设计1．单项式除以单项式的运算法则：单项式相除，把系数、同底数幂分别相除，作为商的因式；对于只在被除式里含有的字母，则连同它的指数作为商的一个因式．2．单项式除以单项式的应用在教学过程中，通过生活中的情景导入，引导学生根据单项式乘以单项式的乘法运算推导出其逆运算的规律，在探究的过程中经历数学概念的生成过程，从而加深印象
北师大初中七年级数学下册多项式与多项式相乘教案
解：(ax2＋bx＋1)(3x－2)＝3ax3－2ax2＋3bx2－2bx＋3x－2.∵积不含x2项，也不含x项，∴－2a＋3b＝0，－2b＋3＝0，解得b＝32，a＝94，∴系数a、b的值分别是94，32.方法总结：解决此类问题首先要利用多项式乘法法则计算出展开式，合并同类项后，再根据不含某一项，可得这一项系数等于零，再列出方程解答．三、板书设计1．多项式与多项式的乘法法则：多项式和多项式相乘，先用一个多项式的每一项与另一个多项式的每一项相乘，再把所得的积相加．2．多项式与多项式乘法的应用本节知识的综合性较强，要求学生熟练掌握前面所学的单项式与单项式相乘及单项式与多项式相乘的知识，同时为了让学生理解并掌握多项式与多项式相乘的法则，教学中一定要精讲精练，让学生从练习中再次体会法则的内容，为以后的学习奠定基础
北师大初中七年级数学下册单项式与单项式相乘教案
解析：先求出长方形的面积，再求出绿化的面积，两者相减即可求出剩下的面积．解：长方形的面积是xym2，绿化的面积是35x×34y＝920xy(m2)，则剩下的面积是xy－920xy＝1120xy(m2)．方法总结：掌握长方形的面积公式和单项式乘单项式法则是解题的关键．三、板书设计1．单项式乘以单项式的运算法则：单项式相乘，把系数、同底数幂分别相乘，作为积的因式；对于只在一个单项式里面含有的字母，则连同它的指数作为积的一个因式．2．单项式乘以单项式的应用本课时的重点是让学生理解单项式的乘法法则并能熟练应用．要求学生在乘法的运算律以及幂的运算律的基础上进行探究．教师在课堂上应该处于引导位置，鼓励学生“试一试”，学生通过动手操作，能够更为直接的理解和应用该知识点
北师大初中七年级数学下册利用“边边边”判定三角形全等教案
解析：由于多边形(三边以上的)不具有稳定性，将其转化为三角形后木架的形状就不变了．根据具体多边形转化为三角形的经验及题中所加木条可找到一般规律．解：过n边形的一个顶点可以作(n－3)条对角线，把多边形分成(n－2)个三角形，所以，要使一个n边形木架不变形，至少需要(n－3)根木条固定．方法总结：将多边形转化为三角形时，所需要的木条根数，可从具体到一般去发现规律，然后验证求解．三、板书设计1．边边边：三边对应相等的两个三角形全等，简写成“边边边”或“SSS”．2．三角形的稳定性本节课从操作探究活动入手，有效地激发了学生的学习积极性和探究热情，提高了课堂的教学效率，促进了学生对新知识的理解和掌握．从课堂教学的情况来看，学生对“边边边”掌握较好，达到了教学的预期目的．存在的问题是少数学生在辅助线的构造上感到困难，不知道如何添加合理的辅助线，还需要在今后的教学中进一步加强巩固和训练
北师大初中七年级数学下册利用“边角边”判定三角形全等教案
AD＝CD，∠ADE＝∠CDG，DE＝GD，∴△ADE≌△CDG(SAS)，∴AE＝CG；(2)设AE与DG相交于M，AE与CG相交于N.在△GMN和△DME中，由(1)得∠CGD＝∠AED，又∵∠GMN＝∠DME，∠DEM＋∠DME＝90°，∴∠CGD＋∠GMN＝90°，∴∠GNM＝90°，∴AE⊥CG.三、板书设计1．边角边：两边及其夹角分别相等的两个三角形全等，简写成“边角边”或“SAS”．两边和其中一边的对角对应相等的两个三角形不一定全等．2．全等三角形判定与性质的综合运用本节课从操作探究入手，具有较强的操作性和直观性，有利于学生从直观上积累感性认识，从而有效地激发了学生的学习积极性和探究热情，提高了课堂的教学效率，促进了学生对新知识的理解和掌握．从课堂教学的情况来看，学生对“边角边”掌握较好，但在探究三角形的大小、形状时不会正确分类，需要在今后的教学和作业中进一步加强分类思想的巩固和训练
