1、对课本知识分类整理,理清脉络
复习一定要有目的,有重点,要对所学知识归纳,概括。一定要理清每一个单元的重点是什么,形成知识网络体系。要分析之前做过的卷子和平时在课堂上作的听课笔记,把重要概念、重要公式牢记。
2、多做一些题型
数学永远离不开习题,要每天做适当的练习,特别是重点和热点题型,从而保持思维的灵活和流畅。习题要具有开放性,创新性,使思维得到充分发展。要借助习题正确评估自己,自觉查漏补缺。面对复杂多变的题目,严密审题,弄清知识结构关系和知识规律,发掘隐含条件,多思多找,得出自己的经验。
3、充分利用错题本
要加强对以往错题的研究,找错误的原因,对易错知识点进行列举、易误用的方法进行归纳。找准了错误的原因,就能对症下药,使犯过的错误不再发生。学习成绩优秀稳定的同学,往往很重视订正和收集错题。
4、练习一题多解,多题一解,提高解题的灵活性
有些题目,可以从不同的角度去分析,得到不同的解题方法。一题多解可以培养分析问题的能力,灵活解题的能力。不同的解题思路,列式不同,结果相同,收到殊途同归的效果。同时也给其他同学以启迪,开阔解题思路。有些应用题,虽题目形式不同,但它们的解题方法是一样的,故在复习时,要从不同的角度去思考,要对各类习题进行归类,这样才能使所学知识融会贯通,提高解题灵活性。
5、要养成检查的习惯
复习时如能注意检查的重要性,效果也会事半功倍。如检查列式是否正确。读题,看是否该用加法、减法、乘法或是除法来算。列式正确后,看算式中的数字是否抄错,是否和题中给我们的一样。检查单位和答案有没有填写齐全。解方程题,要记得写“解”,应用题还要先“设”等。

另外,给大家总结了三年级上期数学的知识点,大家可以参考:
