一年级20以内连加连减口算练习题
一年级20以内连加连减口算练习题对于一年级的小朋友来说，掌握 20 以内的连加连减口算能力是数学学习中非常重要的一环。
为了帮助小朋友们更好地练习和提高这一能力，以下为大家准备了一系列的练习题。
首先，让我们来了解一下什么是 20 以内的连加连减。
连加就是把三个或三个以上的数相加，例如 2 ＋ 3 ＋ 5 ＝ 10 ；连减则是从一个数中连续减去两个或两个以上的数，比如 15 3 2 ＝ 10 。
为了让小朋友们熟悉这种计算方式，我们来做几道简单的练习题。
第一组：1、 3 ＋ 2 ＋ 5 ＝2、 1 ＋ 4 ＋ 6 ＝3、 2 ＋ 1 ＋ 7 ＝4、 4 ＋ 3 ＋ 2 ＝5、 5 ＋ 1 ＋ 3 ＝这一组练习题主要是让小朋友们先感受一下连加的运算，数字都比较小，容易计算。
接下来是第二组：1、 7 ＋ 3 ＋ 1 ＝3、 5 ＋ 4 ＋ 2 ＝4、 9 2 3 ＝5、 6 ＋ 3 1 ＝这一组的题目稍微增加了一点难度，既有连加，又有连减。
然后是第三组：1、 4 ＋ 5 ＋ 3 ＝2、 10 4 2 ＝3、 3 ＋ 6 ＋ 4 ＝4、 8 3 2 ＝5、 7 ＋ 2 ＋ 1 ＝这一组的数字会更大一些，需要小朋友们更加认真地计算。
再来看第四组：1、 5 ＋ 7 3 ＝2、 9 ＋ 1 5 ＝3、 6 ＋ 5 2 ＝4、 12 3 4 ＝这一组的题目难度又有所提升，需要小朋友们更加细心。
最后是第五组：1、 7 ＋ 5 4 ＝2、 11 2 3 ＝3、 4 ＋ 8 2 ＝4、 10 5 3 ＝5、 6 ＋ 6 5 ＝做完这些练习题之后，小朋友们可以自己检查一下答案，看看自己做对了多少。
如果做错了，也不要灰心，多练习几次就会越来越熟练的。
在做 20 以内连加连减口算练习题的时候，小朋友们可以先从左到右依次计算，先算出前面两个数的结果，再和第三个数进行计算。
比如 3 ＋ 5 ＋ 2 ，先算 3 ＋ 5 ＝ 8 ，再算 8 ＋ 2 ＝ 10 。
一年级20以内连加连减口算练习题
一年级20以内连加连减口算练习题对于一年级的小朋友来说，掌握 20 以内的连加连减口算能力是数学学习中非常重要的一步。
这不仅能够帮助他们提高计算速度和准确性，还能为今后更复杂的数学运算打下坚实的基础。
为了让孩子们更好地练习 20 以内的连加连减，我们可以设计多种形式的练习题。
比如：一、直接计算型1、 3 ＋ 5 ＋ 2 ＝2、 9 4 2 ＝3、 2 ＋ 7 ＋ 1 ＝4、 8 3 1 ＝5、 4 ＋ 6 ＋ 3 ＝6、 7 2 3 ＝7、 1 ＋ 8 ＋ 2 ＝8、 6 1 4 ＝在这类题目中，孩子们需要直接按照顺序进行计算，锻炼他们的基本运算能力。
二、填空型1、（）＋ 3 ＋ 4 ＝ 102、 8 （） 1 ＝ 43、 2 ＋（）＋ 3 ＝ 94、 7 （） 2 ＝ 25、（）＋ 5 ＋ 1 ＝ 116、 6 （） 3 ＝ 0这种填空的形式可以帮助孩子们更好地理解运算的逻辑，培养他们的逆向思维能力。
三、比较大小型1、 2 ＋ 5 ＋ 3 （） 102、 9 3 2 （） 43、 4 ＋ 6 1 （） 94、 8 2 3 （） 3通过比较大小，孩子们能够更加直观地感受计算结果的大小关系，增强他们对数字的敏感度。
四、应用题型1、小明有 5 个苹果，小红给了他 3 个，小刚又拿走了 2 个，小明现在有几个苹果？2、树上原来有 8 只鸟，飞来了 4 只，又飞走了 3 只，树上现在有几只鸟？3、妈妈买了 10 个橘子，给了弟弟 2 个，给了妹妹 3 个，还剩下几个橘子？应用题能够让孩子们将数学运算与实际生活场景相结合，提高他们运用数学知识解决问题的能力。
在让孩子们做这些练习题的时候，家长和老师可以给予适当的指导和鼓励。
对于做错的题目，要帮助他们分析错误的原因，及时纠正。
同时，可以采取一些有趣的方式，比如设置时间限制，进行小比赛等，激发孩子们的学习兴趣和积极性。
还可以通过游戏的方式来加强练习，比如制作数字卡片，让孩子们随机抽取进行连加连减的计算；或者玩“数字接龙”的游戏，一个孩子说出一个算式的结果，另一个孩子接着出一个算式，依次进行。
