小学五年级下册数学教学计划

一、学生情况分析：
我执教五（1）五（2）两个班级的数学教学，五2班44人，五3班3 2人。
在上学期师生的共同努力下，这两个班的数学虽有些进步，但与其他兄弟学校相
比较而言 ，还是有相当大的距离。学生方面，主要是基础知识和基本技能不扎实，
如计算方面，好多学生整数乘除 就没有学好，计算错误率高，以至全班平均分不
高，优生差生两极分化比较严重。学生的作业习惯不好， 每班都有10来位学生
经常有不自觉完成作业的现象，要班主任齐抓共管，按时完成问题。学生合作交< br>流能力和自主探讨能力不高，有待进一步提高。有相当一部分的学生基础知识差,
不能自觉的完成 学习任务,需要老师督促并辅导。本学期利用中午时间，重点抓
好学习上有困难的学生教学。同时辅导好 优生，使两个班更多学生争取考到90
分以上。
二、教材分析
本册教学内容包括， 图形的变换，因数与倍数，长方体和正方体，分数的意
义和性质，分数的加法和减法，统计，数学广角和 综合应用等。
在数与代数方面，这一册教材安排了因数与倍数、分数的意义和性质，分数
的加法和减法。因数与倍数，在前面学习整数及其四则运算的基础上教学初等数
论的一些基础知识，包 括因数和倍数的意义，2、5、3的倍数的特征，质数和合
数。教材在三年级上册分数的初步认识的基础 上教学分数的意义和性质以及分数
的加法、减法，结合约分教学最大公因数，结合通分教学最小公倍数。
在空间与图形方面，这一册教材安排了图形的变换、长方体和正方体两个单
元。在已有知 识和经验的基础上，通过丰富的现实的数学活动，让学生获得探究
学习的经历，认识图形的轴对称和旋转 变换；探索并体会长方体和正方体的特征、
图形之间的关系，及图形之间的转化，掌握长方体、正方体的 体积及表面积公式，
探索某些实物体积的测量方法，促进学生空间观念的进一步发展。
在统计方面，本册教材让学生学习有关众数和复式折线统计图的知识。在学
习平均数和中位数的基础上， 本册教材教学众数。平均数、中位数和众数都是反
映一组数据集中趋势的特征数。平均数作为一组数据的 代表，比较稳定、可靠，

但易受极端数据的影响；中位数作为一组数据的代表，可靠性比较差，但不 受极
端数据的影响；众数作为一组数据的代表，也不受极端数据的影响。当一组数据
中个别数据 变动较大时，适宜选择众数或中位数来表示这组数据的集中趋势。
在用数学解决问题方面，教 材一方面结合分数的加法和减法、长方体和正
方体两个单元，教学用所学的知识解决生活中的简单问题； 另一方面，安排了“数
学广角”的教学内容，引导学生通过观察、猜测、实验、推理等活动向学生渗透< br>优化的数学思想方法，体会解决问题策略的多样性及运用优化的方法解决问题的
有效性，感受数学 的魅力。
本册教材根据学生所学习的数学知识和生活经验，安排了两个数学综合应
用活 动，让学生通过小组合作的探究活动或有现实背景的活动，运用所学知识解
决问题，体会探索的乐趣和数 学的实际应用，感受用数学的愉悦，培养学生的数
学意识和实践能力。
