小学数学的学习方法总结,小学生学习数学8个小技巧!

小学数学 04-18 浏览量: 分享:

        小学数学的学习方法总结,小学生学习数学8个小技巧!数学是小学课程的重头戏,但有些孩子却因为没有理解算数概念,或者粗心大意,就很难打下坚实的基础。其实数学是一门活学的课程,很多时候老师教学方式太过一板一眼,孩子反而很难吸收。

 

  在这里,三好网小学家教班老师介绍了8个神奇的数学小技巧,爸爸妈妈这么教会孩子,绝对让孩子不再抱怨数学很难。


  1.比比数字


  有些低年级的小学生在比数字大小时,容易用错“<”和“>”这两个比较符号。


  家长不妨让孩子记住,符号方向就像是鳄鱼嘴巴一样,当然越大的越好吃!


  2.九九乘法表


  九九乘法表的背诵很吃力?其实只要在十位数上从0写到9,个位数上从9到数回0,马上写出完整的表格。考试更轻松!


  3.两位数乘法(90以上)


  两位数的乘法很容易让孩子漏算数字,特别是90以上的互乘就更难了。


  其实有这样的简单技巧,比如97x96=9312来说,只要拿100减乘数与被乘数,把答案分别相乘与相加,把乘出来的答案摆在后面,用100减加出来的总和后摆在前面,答案竟然神奇得和传统算法一模一样。试试吧!


  4.两位数和11相乘


  任何二位数和11相乘,只要把十位数和个位数拆开,中间再插入十位数和个位数的总和,就不用麻烦地乘来乘去啦。


  5.分数的加减


  以往会找出两分母的最小公倍数再计算。但其实只要在算式上画只蝴蝶就解决了。把蝴蝶翅膀圈在一起的部分相乘写在触角里面,彼此相加就是答案的分子,再把分母彼此相乘,就是答案的分母。减法也是一样的方式,只要把触角里的数字改成相减即可。


  6.分数和整数的乘法


  如图:把分母和整数间连一条线,算出24是4的6倍,然后再把线连到分子3,用6乘以3,答案18就这么轻松算出来。


  7.计算百分比


  计算百分比的时候,其实“%”就能抵消两个零。比如计算“300的12%”时,只需要把“300”后面的两个“0”去掉,就可以划去“%”了,剩下就是“3x12=36”了,是不是很轻松。


  如果两个数都有出现个位数是“0”的情况下,网友还提供了另一种方式:


  8.十几乘十几


  口诀:头乘头,尾加尾,尾乘尾


  例:12×14=?


  口诀算法:1×1=12+4=62×4=8


  答案:12×14=168


  注:个位相乘,不够两位数要用0占位。个位相乘后是两位数,记得加在前一位!


  比如13x16=?


  口诀算法:1x1=13+6=93x6=18


  此时的18的十位数“1”就要和“9”加在一起,等于“10”后,又往百位数前进一步,让百位数的1变成2,这样13x16=208.


  看看是不是这样吧?


  学习数学的秘诀


  1.课堂上特别要抓住基础知识和基本技能的学习,课后要及时复习不留疑点。


  2.多做题目是必须的,熟悉掌握各种题型的解题思路。刚开始要从基础题入手,以课本上的习题为准,反复练习打好基础,再找一些课外的习题,以帮助开拓思路,提高自己的分析、解决能力,掌握一般的解题规律。


  3.对于一些易错题,可备有错题集,写出自己的解题思路和正确的解题过程,两者一起比较找出自己的错误所在,以便及时更正。


  4.在平时要养成良好的解题习惯。让自己的精力高度集中,使大脑兴奋,思维敏捷,能够进入最佳状态,在考试中能运用自如。实践证明:越到关键时候,孩子所表现的解题习惯与平时练习密切相关。
