高三了数学很差怎么办 如何提高数学成绩

进入高三复习阶段以后，一些数学基础较差的学生往往会感到压力较大，很难适应高三数学的复习节奏。那么怎样才能提高自己的数学成绩呢？小编整理了《高三了数学很差怎么办 如何提高数学成绩》，供大家参考！

一、数学成绩差的原因

1.数学基础知识差

高三数学成绩差的同学首先表现在基础知识掌握不全，对有的知识掌握的好，而有的知识基本不知道。所以在做题的时候就只能做一部分，甚至有的题目一开始就做不下去。还有的同学最基础知识一知半解，甚至只是死记硬背下来而已，因此题目稍有变化就蒙了。

2.数学学习习惯较差

高中数学知识学习有一定的难度，所以这需要学生不断地思考来提高学生的数学能力和思维水平。但是数学学困生往往只是在课堂上只满足于听得懂,一知半解或是在听课时忙于记笔记,根本没听懂内容。这样长此以往想要学好数学根本就是天方夜谭。

二、提高数学成绩的方法

1.制定学习计划

到了高三，数学基础差的同学只有一年的时间来弥补。所以你要明白这一年的时间里，你的数学要达到什么样的目标。比如你现在的数学成绩是60分（150满计算），经过一年的努力你想达到什么样的成绩，以此作为依据来分配好自己的学习计划。

2.懂得舍弃

在高三一年的时间里，你不可能将全部的数学知识都完全掌握，所以这个时候你就要懂得舍弃，要做到抓大放小。根据考试大纲，把重心放在基础题目上和分数多的题目上，像是难题和压轴题就可以适当的选择放弃。

3.学习数学要有越挫越勇的精神

在提升数学成绩的过程中，暂时看不到进步是很正常的事情。这个时候一定不要泄气，要相信在高考之前，你只要努力就不会晚。对于试卷中出现的问题要科学分析，也可以找老师或同学帮自己分析，快速解决，不要把时间浪费在“丧失信心的没状态中”。
