小学一年级数学《连加、连减》教学设计(精选3篇)

⼩学⼀年级数学《连加、连减》教学设计(精选3篇)⼩学⼀年级数学《连加、连减》教学设计(精选3篇) 作为⼀位优秀的⼈民教师,通常会被要求编写教学设计,借助教学设计可以提⾼教学质量,收到预期的教学效果。
我们应该怎么写教学设计呢?以下是⼩编为⼤家整理的⼩学⼀年级数学《连加、连减》教学设计(精选3篇),欢迎⼤家分享。
⼀年级数学《连加、连减》教学设计1 教学内容:P72连加连减 教学重点:掌握连加、连减的计算⽅法,正确进⾏计算。
教学难点:理解图意,正确列出算式。
教学⽤具:贴图、投影⽚。
教学过程: ⼀、复习 看谁算得⼜对⼜快。
4+2=5+2=7+1=2+1=3+5=6+2=8+2= 4+4=8+1=7-2=5-3=9-7=2-2=8-5 3-2=10-3=7-2=6-1=5-2=1+3= ⼀、新知 (⼀)、1、出⽰玩具图(投影) 2、⽣观察说图意,你发现了什么数学问题? 3、⼀共有⼏个玩具?你会列式吗? 4、指⽣汇报,列式。
师板书:4+3+2=9 5、⼩组讨论,7这个算式怎么计算? 6、说说算式表⽰的意思 7、还可以怎样列式计算?师板书:4+2+32+4+33+4+2…… 8、⽣说算式怎样计算? 9、运算顺序:先⽤第⼀个数和第⼆个数相加,再⽤得数加上第三个数 板书:连加计算 (⼆)、出⽰买鱼图(投影) 1、看图说图意 2、根据图意列式10-2-2 3、读算式 4、试着算⼀算,⽣尝试练习 5、说说你是怎样计算的?板书:10-3-2=5 6、哪位同学说说这是⼀道什么题?板书:连减 7、请同学们想想连加和连减题再计算⽅法上有什么相同的地⽅。
课间休息放⾳乐做操。
⼆、练习 1、把复习题中每组相关的题合并成⼀道连加或连减题并计算(投影) 1+3+2=5+2+1=2+1+5=6+2+2= 4+4+1=7-2-3=9-7-2=8-5-2= 10-3-2=6-1-2= 3、先把算式补充完整,然后列式计算。

1年级20以内连加连减法混合计算题

1年级20以内连加连减法混合计算题全文共四篇示例,供读者参考第一篇示例:在小学一年级的数学学习中,加法和减法是最基础的运算之一。
通过练习连加和连减法,孩子们可以提高他们的计算能力和思维逻辑能力。
今天我们就来制作一份关于一年级20以内连加连减法混合计算题,让孩子们在练习中提升他们的数学技能。
我们来看一下一年级学生的数学知识点。
在一年级,学生学习的加减法范围一般在20以内。
我们设计的题目也以20以内的数字为主。
接下来,我们将制作一些连加和连减法混合计算题目,让学生在练习中能够灵活运用这些计算方法。
1. 8 + 5 - 2 = ?2. 6 - 2 + 7 = ?3. 10 + 3 - 4 = ?4. 9 - 3 + 5 = ?5. 12 + 4 - 3 = ?6. 7 - 1 + 6 = ?7. 15 + 2 - 1 = ?8. 11 - 4 + 6 = ?9. 13 + 3 - 2 = ?10. 8 - 2 + 5 = ?这些题目不仅考察了学生对于加法和减法的理解,还让他们学会在连加和连减中进行灵活转换。
通过这些练习题目,孩子们可以在实践中提升他们的数学技能,培养他们的逻辑思维能力。
希望这些题目对于一年级的学生有所帮助,让他们在数学学习中更加得心应手。
第二篇示例:小明是一名一年级的学生,最近在数学课上学习了20以内的加法和减法运算。
老师布置了一份练习题,要求小明完成20以内的连加和连减法混合计算题。
小明拿过题纸,看着上面密密麻麻的数字,心里有些忐忑,但是他下定决心要认真完成这份练习。
小明开始做连加法的题目。
题目上写着:“15+4-7+6-2=?”小明握紧铅笔,仔细算了起来。
先算加法部分,15+4=19,然后减法部分,19-7=12,再加法部分,12+6=18,最后减法部分,18-2=16。
小明算完之后,把答案写在题目旁边,然后继续做下一道题目。
小明在练习过程中,时而用手指点在题目上计算,时而默默地在脑海中进行推算。

一年级20以内加减法(含连加连减)

一年级20以内加减法(含连加连减)一年级20以内加减法(含连加连减)一、基础概念在进行一年级20以内加减法运算之前,我们首先需要了解一些基础概念。
1.1 加法加法是一种数学运算,它将两个或多个数值相加,得到它们的总和。
在加法中,我们将一个数值称为“加数”,另一个数值称为“被加数”,它们的和被称为“和”。
1.2 减法减法是一种数学运算,它将一个数值(被减数)减去另一个数值(减数),得到它们的差。
在减法中,我们将被减数减去减数,得到的结果称为“差”。
1.3 连加和连减连加是指连续多次进行加法运算,将多个数值依次相加,得到它们的总和。
类似地,连减是指连续多次进行减法运算,将多个数值依次相减,得到它们的差。
二、一年级20以内加减法练习现在,我们来进行一年级20以内加减法的练习。
请按照以下步骤进行。
2.1 加法练习(1)首先,我们从最简单的加法题目开始,逐步增加难度。
例题1:1 + 2 = ___解答过程:将1加上2,得到3。
因此,1 + 2 = 3。
(2)接下来,让我们练习一些连加题目。
例题2:3 + 4 + 5 = ___解答过程:先将3和4相加,得到7,再将7和5相加,得到12。
因此,3 + 4 + 5 = 12。
2.2 减法练习(1)现在,让我们进行一些基础的减法练习。
例题3:7 - 3 = ___解答过程:将7减去3,得到4。
因此,7 - 3 = 4。
(2)接下来,我们尝试一些连减题目。
例题4:12 - 5 - 3 = ___解答过程:先将12减去5,得到7,再将7减去3,得到4。
因此,12 - 5 - 3 = 4。
三、巩固练习在掌握了一年级20以内加减法的基本概念和操作方法之后,我们进行一些巩固练习,以确保理解和运用。
3.1 其他加减法题目例题5:8 + 6 - 2 = ___解答过程:首先将8加上6,得到14,再将14减去2,得到12。
因此,8 + 6 - 2 = 12。
例题6:17 - 3 + 4 = ___解答过程:首先将17减去3,得到14,再将14加上4,得到18。
