1：甲、乙、丙三个村庄合修一条水渠，计划需要176个劳动力，由于各村人口数不等，只有按2：3：6的比例摊派才较合理，则三个村庄各派多少个劳动力？2：某校组织活动，共有100人参加，要把参加活动的人分成两组，已知第一组人数比第二组人数的2倍少8人，问这两组人数各有多少人？目的：检测学生本节课掌握知识点的情况，及时反馈学生学习中存在的问题．实际活动效果：从学生做题的情况看，大部分学生都能正确地列出方程，但其中一部分人并不能有意识地用“列表格”法来分析问题，因此，教师仍需引导他们能学会用“列表格”这个工具，有利于以后遇上复杂问题能很灵活地得到解决.六、归纳总结：活动内容：学生归纳总结本节课所学知识：1. 两个未知量，两个等量关系，如何列方程；2. 寻找中间量；3. 学会用表格分析数量间的关系．
北师大初中七年级数学上册应用一元一次方程——水箱变高了教案1
解：设截取圆钢的长度为xmm.根据题意，得π（902）2x＝131×131×81，解方程，得x＝686.44π.答：截取圆钢的长度为686.44πmm.方法总结：圆钢由圆柱形变成了长方体，形状发生了变化，但是体积保持不变.“变形之前圆钢的体积＝变形之后长方体的体积”就是我们所要寻找的等量关系.探究点三：面积变化问题将一个长、宽、高分别为15cm、12cm和8cm的长方体钢坯锻造成一个底面是边长为12cm的正方形的长方体钢坯.试问：是锻造前的长方体钢坯的表面积大，还是锻造后的长方体钢坯的表面积大？请你计算比较.解析：由锻造前后两长方体钢坯体积相等，可求出锻造后长方体钢坯的高.再计算锻造前后两长方体钢坯的表面积，最后比较大小即可.解析：设锻造后长方体的高为xcm，依题意，得15×12×8＝12×12x.解得x＝10.锻造前长方体钢坯的表面积为2×（15×12＋15×8＋12×8）＝2×（180＋120＋96）＝792（cm2），锻造后长方体钢坯的表面积为2×（12×12＋12×10＋12×10）＝2×（144＋120＋120）＝768（cm2）.
