人教版一年级上册数学第8单元20以内的进位加法
第八单元 20以内的进位加法一、教学内容二、教材分析20以内的进位加法是20以内退位减法和多位数计算的基础，这一部分学习的好坏，将对今后计算的正确和迅速程度产生直接的影响。
如果这部分内容没有学好，计算时既慢又容易出错，以后继续学习口算和多位数笔算就会遇到很大困难。
因此，20以内的进位加法也是进一步学习数学必须练好的基本功之一。
用加法和减法解决简单的问题，既有利于学生在用数学中领会加、减法的含义，又可以为以后发现和解决稍复杂的问题打下基础。
教材的编排，大体分三个层次：第一，以实际情境提供计算题，并且呈现多种计算方法；第二，让学生动手操作或观察，理解和掌握算法；第三，脱离实物，让学生思考算法，算出的数。
这样编排，从学生熟悉的情境出发，提出有关的数学问题，容易激发学生的学习兴趣。
同时，由动手操作、观察、依靠动作和实物思考到脱离实物思考，遵循了由具体到抽象的原则，有利于学生抽象思维能力的培养。
20以内进位加法的口算方法不只一种，教材中呈现了多种计算方法，比如在“9加几”部分呈现有“点数”、“接着数”、“凑十”和“根据具体题目选择特殊方法”等；在“8、7、6加几”部分呈现有“拆小数，凑大数”、“拆大数，凑小数”和“交换加数的位置”。
教材注意在具体情境下，让学生自己想出不同的计算方法。
允许学生采用不同的方法进行计算的思想，尊重学生的自主选择。
“凑十法”是学生新接触的一种方法，掌握起来有一定的难度，所以，教材专门安排例题进行教学。
掌握好“凑十法”对进一步学习其它计算都有好处。
本单元继续渗透一些集合、函数、统计等数学思想，教材中的“用数学”编排在计算当中，呈现形式是用学生熟悉的事物设计情境图，为学生发现问题、探索数学问题提供生动有趣的资源。
“用数学”要求学生经历观察发现数学问题，收集解决问题需要的信息、数据，探求解决问题的方法，求得问题解决的全过程。
实质上是学生运用数学知识的学习活动，对学生体会加、减运算的含义，产生学习数学的兴趣起重要作用。

一年级20以内进位加法练习题
一年级20以内进位加法练习题
一年级的学生正在研究20以内的进位加法，以下是一些
练题：
1.12 + 8 = 20
2.15 + 6 = 21
3.9 + 13 = 22
4.7 + 14 = 21
5.11 + 9 = 20
这些练题可以帮助学生加深对进位加法的理解和掌握。
老师可以让学生自己完成这些题目，也可以在课堂上进行口算练。
此外，老师还可以通过游戏的方式来帮助学生加强对进位加法的记忆和理解。
例如，可以在黑板上画出一个数轴，让学生在数轴上移动，找到正确的答案。
这样的游戏不仅可以让学生在轻松愉快的氛围中研究，还可以增强他们的参与度和兴趣。
总之，通过练题和游戏的方式，一年级的学生可以更好地掌握20以内的进位加法，为以后的研究打下坚实的基础。

【小学数学】人教版一年级上册数学第八单元《20以内的进位加法》知识点+练习题
《20以内的进位加法》知识点1.掌握20以内进位加法的计算方法---“凑十法”“凑小数;拆大数”将小数凑成10;然后再计算。
如：3+9（3+7=10,9可以分成7和2,10+2=12）将大数凑成10;然后再计算。
“凑大数;拆小数”；如：8+7（8+2=10,7可以分成2和5;10+5=15）注意：孩子喜欢和熟悉的方法才是最佳方法而且只掌握一种就可以了。
2.20以内不进位加法和不退位减法：11+6（个位相加;1+6=7）11+6=1715-3（个位上够减;5-3=2）15-3=123、加强进位和不进位、及不退位的训练。
4、看图列式解题时候;要利用图中已知条件正确列式。
常用的关系有：（1）部分数+部分数=总数（2）总数-部分数=另一个部分数（3）大数-小数=相差数（谁比谁多几;或谁比谁少几）（4）原有-借出=剩下（用了多少;求还剩多少时用）20以内的进位加法口算练习题（一）1) 12+3= 2) 18+2= 3) 10+6= 4) 6+11= 5) 2+18= 6) 4+15= 7) 12+3= 8) 0+12= 9) 11+2= 10) 12+1= 11) 1+17= 12) 1+14= 13) 0+19= 14) 15+2= 15) 15+1= 16) 0+16= 17) 3+17= 18) 1+15= 19) 14+0= 20) 14+3= 21) 0+19= 22) 4+12= 23) 16+1= 24) 1+11= 25) 0+14= 26) 2+13= 27) 0+17= 28) 12+1= 29) 10+3= 30) 19+0= 31) 4+10= 32) 16+0= 33) 14+0= 34) 15+3= 35) 5+11= 36) 18+1= 37) 11+2= 38) 17+3= 39) 17+0= 40) 13+0= 41) 13+2= 42) 3+10= 43) 1+13= 44) 16+2= 45) 18+0= 46) 0+13= 47) 7+10= 48) 14+1= 49) 3+14= 50) 1+12=20以内的进位加法口算练习题（二）姓名：_____________ 时间：__________ 做对了_____题（共50题）( 1) 5+8= 2) 7+6= 3) 2+10= 4) 7+5= 5) 9+6=6) 8+6= 7) 4+9= 8) 6+7= 9) 8+3= 10) 7+8=11) 9+5= 12) 7+7= 13) 5+6= 14) 2+9= 15) 5+9=16) 8+5= 17) 5+9= 18) 7+6= 19) 6+6= 20) 9+5=21) 6+8= 22) 8+7= 23) 3+8= 24) 7+9= 25) 3+10=26) 10+5= 27) 10+1= 28) 8+7= 29) 5+8= 30) 7+7=31) 5+10= 32) 8+5= 33) 5+6= 34) 5+9= 35) 9+9=36) 5+9= 37) 6+5= 38) 7+8= 39) 4+8= 40) 9+6=41) 8+7= 42) 6+7= 43) 5+8= 44) 6+7= 45) 7+5=46) 6+8= 47) 8+3= 48) 8+3= 49) 7+8= 50) 6+6=20以内的不退位减法口算练习题（三）姓名：_____________ 时间：__________ 做对了_____题（共50题） 1) 17-5= 2) 14-0= 3) 17-3= 4) 15-1= 5) 14-0=6) 13-2= 7) 17-3= 8) 17-5= 9) 11-0= 10) 13-1=11) 19-4= 12) 16-5= 13) 15-1= 14) 17-6= 15) 16-0=16) 18-3= 17) 19-5= 18) 18-6= 19) 16-0= 20) 17-5=21) 18-4= 22) 16-3= 23) 13-1= 24) 15-1= 25) 16-4=26) 18-1= 27) 12-0= 28) 19-0= 29) 19-0= 30) 18-1=31) 17-2= 32) 19-0= 33) 18-4= 34) 18-3= 35) 19-2=36) 15-0= 37) 19-3= 38) 13-1= 39) 18-1= 40) 18-4=41) 19-2= 42) 15-1= 43) 11-0= 44) 18-7= 45) 17-2=46) 18-6= 47) 16-4= 48) 18-0= 49) 17-5= 50) 19-5=20以内的退位减法口算练习题（四）姓名：_____________ 时间：__________ 做对了_____题（共50题） 1) 13-4= 2) 13-5= 3) 12-4= 4) 10-4= 5) 14-8=6) 17-9= 7) 10-6= 8) 10-5= 9) 17-9= 10) 12-7=11) 14-9= 12) 14-8= 13) 11-8= 14) 11-2= 15) 11-5=16) 10-7= 17) 15-9= 18) 16-8= 19) 13-5= 20) 11-6=21) 11-6= 22) 15-6= 23) 15-9= 24) 12-3= 25) 13-6=26) 16-7= 27) 13-5= 28) 16-8= 29) 13-9= 30) 10-9=31) 12-4= 32) 15-7= 33) 10-5= 34) 15-9= 35) 11-3=36) 12-7= 37) 10-9= 38) 10-4= 39) 11-7= 40) 13-9=41) 11-5= 42) 10-7= 43) 12-6= 44) 11-3= 45) 17-9=46) 10-8= 47) 10-3= 48) 10-3= 49) 12-8= 50) 15-8=20以内的加法口算练习题（五）姓名：_____________ 时间：__________ 做对了_____题（共50题）1) 5+3= 2) 3+5= 3) 8+5= 4) 2+0= 5) 2+9=6) 1+4= 7) 2+7= 8) 4+3= 9) 6+1= 10) 7+5=11) 9+8= 12) 6+6= 13) 9+0= 14) 7+1= 15) 8+7=16) 1+3= 17) 3+4= 18) 0+1= 19) 9+9= 20) 4+3=21) 0+7= 22) 2+5= 23) 6+2= 24) 5+7= 25) 4+1=26) 8+4= 27) 3+0= 28) 1+1= 29) 4+1= 30) 5+6=31) 4+9= 32) 9+6= 33) 9+5= 34) 3+8= 35) 8+7=36) 8+9= 37) 5+9= 38) 6+6= 39) 3+2= 40) 3+0=41) 6+6= 42) 5+0= 43) 1+8= 44) 5+9= 45) 8+6=46) 7+4= 47) 2+7= 48) 7+1= 49) 1+6= 50) 9+5=20以内的减法口算练习题（六）姓名：_____________ 时间：__________ 做对了_____题（共50题）1) 19-7= 2) 18-7= 3) 9-4= 4) 13-3= 5) 6-5=6) 10-8= 7) 12-1= 8) 17-7= 9) 4-0= 10) 7-4=11) 12-7= 12) 7-4= 13) 15-6= 14) 11-9= 15) 13-5=16) 19-1= 17) 2-2= 18) 16-9= 19) 15-7= 20) 2-1=21) 10-8= 22) 7-0= 23) 9-9= 24) 7-5= 25) 9-4=26) 6-4= 27) 8-3= 28) 17-9= 29) 19-1= 30) 8-3=31) 6-4= 32) 9-6= 33) 7-6= 34) 13-1= 35) 11-6=36) 12-7= 37) 13-2= 38) 9-4= 39) 19-1= 40) 16-0=41) 7-4= 42) 8-7= 43) 19-6= 44) 7-7= 45) 8-6=46) 5-5= 47) 5-0= 48) 19-4= 49) 9-9= 50) 15-2=。
