10以内数字的分合练习题 1 7 1 6 1 6 9 10 10 5 9 6 8 6 1 3 15 15 2 4

14 4 2 42 51 51 练习卷使用说明： 10以内的分与合是我们上半学期学习的一个重点，也是我们整个小学阶段数学计算的起点。我们教材内的加减法计算题，就是从数的分与合引入的，所以也是用分与合来进行计算的。掌握了10以内的分与合，不仅可以快速准确地计算10以内的加减法，对今后学习20以内，100以内，甚至多位数的加减法及乘除法都会产生至关重要的影响。所以请各位家长能重视对孩子进行这部分内容的训练。以下四项训练中，第一、二项属于基础训练；三、四项属于拓展训练。请家长根据孩子的情况，掌握第一、二项后，再进行后两项的训练。 训练一： 1. 请孩子用合成的方法熟读练习卷，按顺序背出各数的合成。 2. 家长和孩子两人对口令： A：2和5合成几？ B：2

和5合成7。上述训练针对题型举例：填空： 想：5和3合成8，所以方框中填8。计算： +4=？想：因为6和4合成10，所以6+4=10。 训练二： 1. 请孩子用分成的方法熟读练习卷，按顺序背出各数的合成。. 家长和孩子两人对口令： A：8可以分成6和几？ B：8可以分成6和2。上述训练针对题型举例：填空： 想：10可以分成2和8，所以方框中填8。 计算：-3=？想：因为9可以分成3和6，所以9-3=6。 训练三： 家长和孩子两人对口令： A：2和几合成5？ B：2和3合成5。此训练针对题型举例： ①+= 想：7和几合成9，因为7和2合成9，所以括号中填2。② + = 训练四： 家长和孩子两人对口令： A：6可以分成几和4？ B：6可以分成2和4。此训练针对题型举例：①-=1 想：8可以分成几和1，因为8可以分成7和1，所以括号中填1。②- =

(教案)四上第3讲：算式谜(乘除法)

第三讲算式谜（乘除法） 一、教学目标：1、学会等量代换的方法，根据给定的元素按关系或数量关系， 找出算式中的未知量。 2、学会利用运算法则和推理方法，将给定的数填入适当的位 置。 3、培养学生思维能力，训练逻辑思维推理能力，养成良好的 思维习惯。 二、教学重点：根据有关的运算法则、数的性质（和、差、积、商的位数和 尾数规律）来进行正确的推理、判断。 三、教学难点：找到解题的突破口。 四、教学准备：PPT 五、教学过程： 第一课时（40分钟） 一、外星游记（5分钟） 师：老师最近找到了一张藏宝图，大家要不要和我一起去探索下这个神秘的藏宝图呢？ 生：想。 师：我们一起来吧。 师：在神奇的数学王国里，还有很多很多的数学宝藏需要我们大家一起去挖掘，我们一起去吧。 (出示课题：算式谜（乘除法）) 二、星海遨游（30分钟） （一）星海遨游1（10分钟） 在下面的□里填上合适的数字。 师：根据除法竖式可得，商的末尾是多少？ 生：0。 师：6除被除数的百位上的数，够商几？ 生：1，并且只能商1，并且有余数，可得，被除数百位上的数大于6，即7，8，9。 师：当被除数百位上的数是7时，百位上的余数是1，十位上的数是多少？生：由6×2=12，可得十位上的数是2；因此被除数是720。 由以上推算可得竖式是：

师：当被除数百位上的数是8时，百位上的余数是2，十位上的数是多少？生：由6×4=24，可得十位上的数是4；因此被除数是840。 由以上推算可得竖式是： 师：当被除数百位上的数是9时，百位上的余数是3，十位上的数是多少？生：由6×6=36，可得十位上的数是6；因此被除数是960。 由以上推算可得竖式是： 师：解决完除法，我们再来看看乘法，根据乘法竖式可得，第一个因数个位上的数与第二个因数的十位数9相乘的积的末尾是4；由9×6=54，可得，第一个因数个位上的数是多少？ 生：第一个因数个位上的数是6； 师：第一个因数个位上的数6与第二个因数的个位数相乘的积的末尾是8；由6×3=18，6×8=48，可得，第二个因数个位上的数是多少？ 生：第二个因数个位上的数是3或8； 师：当第二个因数个位上的数是3，□6×3的积不可能是6□□，因此，第二个因数个位上的数是8，即第二个因数是多少？ 生：第二个因数是98； 师：第一个因数□6×8的积是6□8，由76×8=608，86×8=688，可得，第一个因数十位上的数是多少？ 生：7或8；即第一个因数是76或86。 师：哪个合适？ 生：当第一个因数是76时，76×9=684，符合题意； 由以上推算可得竖式是：

训练中，第一、二项属于基础训练；三、四项属于拓展训练。请家长根据孩子的情况，掌握第一、二项后，再进行后两项的训练。 训练一： 1. 请孩子用合成的方法熟读练习卷，按顺序背出各数的合成。 2. 家长和孩子两人对口令： A：2和5合成几？ B：2和5合成7。上述训练针对题型举例：填空： 想：5和3合成8，所以方框中填8。计算： +4=？想：因为6和4合成10，所以6+4=10。 训练二： 1. 请孩子用分成的方法熟读练习卷，按顺序背出各数的合成。. 家长和孩子两人对口令： A：8可以分成6和几？ B：8可以分成6和2。上述训练针对题型举例：填空： 想：10可以分成2和8，所以方框中填8。 计算：-3=？想：因为9可以分成3和6，所以9-3=6。 训练三： 家长和孩子两人对口令： A：2和几合成5？ B：2和3合成5。此训练针对题型举例： ①+= 想：7和几合成9，因为7和2合成9，所以括号

第10讲 乘除法算式谜

第10讲乘除法算式谜 [例1]下列算式中不同的汉字代表不同的数字，相同的汉字代表相同的数字。它们各代表什么数字时算式成立。 1、因为杯×3的个位是2，根据4×3=12，所以杯代表的数字是4， 2、因为金×3+进位的1的个位是4，根据1×3+1=4，所以金代表的数字是1， 3、因为庚×3的个位是1，根据7×3=21，所以庚代表的数字是7， 4、因为罗×3+进位的2的个位是7，根据5×3+2=17，所以罗代表的数字是5， 5、因为华×3+进位的1的个位是5，根据8×3+1=25，所以华代表的数字是8。 [练1]下式中“数学俱乐部”分别代表哪些数字？ 1、因为部×3的个位是1，根据7×3=21，所以部代表的数字是7， 2、因为乐×3+进位的2的个位是7，根据5×3+2=17，所以乐代表的数字是5， 3、因为俱×3+进位的1的个位是5，根据8×3+1=25，所以俱代表的数字是8， 4、因为学×3+进位的2的个位是8，根据2×3+2=8，所以乐代表的数字是2， 5、因为数×3的个位是2，根据4×3=12，所以数代表的数字是4。 [例2]在右面的□里填上合适的数字。 练2.在下面的□里填上合适的数字。

[例3]在方框中填上合适的数字。

练3．在下面式子中的□内填入适当的数字，使除法算式成立。 [例4]在右面的□中填上适当的数字。 练4：在□内填入适当的数字，使下列除法竖式成立。

[练一练] 1．算式中的每个汉字各代表哪个数字？ 2．请在下面的□里填上适当的数字，使算式成立。 3．请在下面的□里填上适当的数字，使算式成立。4、在空格中填上合适的数字，使竖式成立。

1. 请孩子用合成的方法熟读练习卷，按顺序背出各数的合成。 2. 家长和孩子两人对口令： A：2和5合成几？ B：2和5合成7。上述训练针对题型举例：填空： 想：5和3合成8，所以方框中填8。计算： +4=？想：因为6和4合成10，所以6+4=10。 训练二： 1. 请孩子用分成的方法熟读练习卷，按顺序背出各数的合成。. 家长和孩子两人对口令： A：8可以分成6和几？ B：8可以分成6和2。上述训练针对题型举例：填空： 想：10可以分成2和8，所以方框中填8。 计算：-3=？想：因为9可以分成3和6，所以9-3=6。 训练三： 家长和孩子两人对口令： A：2和几合成5？ B：2和3合成5。此训练针对题型举例： ①+= 想：7和几合成9，因为7和2合成9，所以括号中填2。② + = 训练四： 家长和孩子两人对口令： A：6可以分成几和4？ B：6可以分成2和4。此
