小学数学典型应用题归纳汇总30种题型
小学数学典型应用题归纳汇总30种题型 1 归一问题 【含义】在解题时，先求出一份是多少（即单一量），然后以单一量为标准，求出所要求的数量。这类应用题叫做归一问题。 【数量关系】总量÷份数＝1份数量 1份数量×所占份数＝所求几份的数量 另一总量÷（总量÷份数）＝所求份数 【解题思路和方法】先求出单一量，以单一量为标准，求出所要求的数量。 例1 买5支铅笔要0.6元钱，买同样的铅笔16支，需要多少钱？ 解（1）买1支铅笔多少钱？0.6÷5＝0.12（元） （2）买16支铅笔需要多少钱？0.12×16＝1.92（元） 列成综合算式0.6÷5×16＝0.12×16＝1.92（元） 答：需要1.92元。 2 归总问题 【含义】解题时，常常先找出“总数量”，然后再根据其它条件算出所求的问题，叫归总问题。所谓“总数量”是指货物的总价、几小时（几天）的总工作量、几公亩地上的总产量、几小时行的总路程等。 【数量关系】1份数量×份数＝总量 总量÷1份数量＝份数 总量÷另一份数＝另一每份数量 【解题思路和方法】先求出总数量，再根据题意得出所求的数量。 例1 服装厂原来做一套衣服用布3.2米，改进裁剪方法后，每套衣服用布2.8米。原来做791套衣服的布，现在可以做多少套？ 解（1）这批布总共有多少米？ 3.2×791＝2531.2（米） （2）现在可以做多少套？2531.2÷2.8＝904（套） 列成综合算式 3.2×791÷2.8＝904（套） 答：现在可以做904套。。 3 和差问题 【含义】已知两个数量的和与差，求这两个数量各是多少，这类应用题叫和差问题。 【数量关系】大数＝（和＋差）÷2 小数＝（和－差）÷2 【解题思路和方法】简单的题目可以直接套用公式；复杂的题目变通后再用公式。

奥数知识点分类汇总(包含公式)
奥数知识点分类汇总（包含公式） 1．和差倍问题 和差问题和倍问题差倍问题 已知条件几个数的和与差几个数的和与倍数几个数的差与倍数 公式适用范围已知两个数的和，差，倍数关系 公式①(和－差)÷2=较小数 较小数＋差=较大数小学奥数很简单，就这30个知识点 和－较小数=较大数 ②(和＋差)÷2=较大数 较大数－差=较小数 和－较大数=较小数 和÷(倍数＋1)=小数 小数×倍数=大数 和－小数=大数 差÷(倍数-1)=小数 小数×倍数=大数 小数＋差=大数 关键问题求出同一条件下的 和与差和与倍数差与倍数 2．年龄问题的三个基本特征： ①两个人的年龄差是不变的； ②两个人的年龄是同时增加或者同时减少的； ③两个人的年龄的倍数是发生变化的； 3．归一问题的基本特点：问题中有一个不变的量，一般是那个“单一量”，题目一般用“照这样的速度”……等词语来表示。 关键问题：根据题目中的条件确定并求出单一量； 4．植树问题 基本类型在直线或者不封闭的曲线上植树，两端都植树在直线或者不封闭的曲线上植树，两端都不植树在直线或者不封闭的曲线上植树，只有一端植树封闭曲线上植树 基本公式棵数=段数＋1 棵距×段数=总长棵数=段数－1 棵距×段数=总长棵数=段数 棵距×段数=总长 关键问题确定所属类型，从而确定棵数与段数的关系 5．鸡兔同笼问题 基本概念：鸡兔同笼问题又称为置换问题、假设问题，就是把假设错的那部分置换出来；基本思路： ①假设，即假设某种现象存在（甲和乙一样或者乙和甲一样）：
②假设后，发生了和题目条件不同的差，找出这个差是多少； ③每个事物造成的差是固定的，从而找出出现这个差的原因； ④再根据这两个差作适当的调整，消去出现的差。 基本公式： ①把所有鸡假设成兔子：鸡数＝（兔脚数×总头数－总脚数）÷（兔脚数－鸡脚数） ②把所有兔子假设成鸡：兔数＝（总脚数一鸡脚数×总头数）÷（兔脚数一鸡脚数） 关键问题：找出总量的差与单位量的差。 6．盈亏问题 基本概念：一定量的对象，按照某种标准分组，产生一种结果：按照另一种标准分组，又产生一种结果，由于分组的标准不同，造成结果的差异，由它们的关系求对象分组的组数或对象的总量． 基本思路：先将两种分配方案进行比较，分析由于标准的差异造成结果的变化，根据这个关系求出参加分配的总份数，然后根据题意求出对象的总量． 基本题型： ①一次有余数，另一次不足； 基本公式：总份数＝（余数＋不足数）÷两次每份数的差 ②当两次都有余数； 基本公式：总份数＝（较大余数一较小余数）÷两次每份数的差 ③当两次都不足； 基本公式：总份数＝（较大不足数一较小不足数）÷两次每份数的差 基本特点：对象总量和总的组数是不变的。 关键问题：确定对象总量和总的组数。 7．牛吃草问题 基本思路：假设每头牛吃草的速度为“1”份，根据两次不同的吃法，求出其中的总草量的差；再找出造成这种差异的原因，即可确定草的生长速度和总草量。 基本特点：原草量和新草生长速度是不变的； 关键问题：确定两个不变的量。 基本公式： 生长量=（较长时间×长时间牛头数-较短时间×短时间牛头数）÷（长时间-短时间）； 总草量=较长时间×长时间牛头数-较长时间×生长量； 8．周期循环与数表规律 周期现象：事物在运动变化的过程中，某些特征有规律循环出现。 周期：我们把连续两次出现所经过的时间叫周期。 关键问题：确定循环周期。 闰年：一年有366天； ①年份能被4整除；②如果年份能被100整除，则年份必须能被400整除； 平年：一年有365天。 ①年份不能被4整除；②如果年份能被100整除，但不能被400整除； 9．平均数 基本公式：①平均数=总数量÷总份数 总数量=平均数×总份数

小学五年级下册奥数题型分类讲义 (附答案)
小学五年级奥数分类讲义含答案 图形问题 专题1 长方形、正方形的周长 一、专题解析 同学们都知道，长方形的周长=（长＋宽）×2，正方形的周长=边长×4。长方形、正方形的周长公式只能用来计算标准的长方形和正方形的周长。 那么如何应用所学知识巧求表面上看起来不是长方形或正方形的图形的周长呢？还需同学们灵活应用已学知识，掌握转化的思考方法，把复杂的图形转化为标准的图形，以便计算它们的周长。 二、精讲精练 【例题1】 有5张同样大小的纸如下图（a）重叠着，每张纸都是边长6厘米的正方形，重叠的部分为边长的一半，求重叠后图形的周长。 【思路导航】根据题意，我们可以把每个正方形的边长的一半同时向左、右、上、下平移（如图b），转化成一个大正方形，这个大正方形的周长和原来5个小正方形重叠后的图形的周长相等。因此，所求周长是18×4=72厘米。 练习1 1、右图由8个边长都是2厘米的正方形组成，求这个图形的周长。 2、右图由1个正方形和2个长方形组成，下方长方形长为50cm，求这 个图形的周长。 3、有6块边长是1厘米的正方形，如例题中所说的这样重叠着，求重叠后图 形的周长。
【例题2】 一块长方形木板，沿着它的长度不同的两条边各截去4厘米，截掉的面积为192平方厘米。现在这块木板的周长是多少厘米？ 【思路导航】把截掉的192平方厘米分成A、B、C三块（如图），其中AB的面积是192－4×4=176（平方厘米）。把A和B移到一起拼成一个宽4厘米的长方形，而此长方形的长就是这块木板剩下部分的周长的一半。176÷4=44（厘米），现在这块木板的周长是44×2=88（厘米）。 练习2 1、有一个长方形，如果长减少4米，宽减少2米，面积就比原来减少44平方米，且剩下部分正好是一个正方形。求这个正方形的周长。 2、有两个相同的长方形，长是8厘米，宽是3厘米，如果按下图叠放在一起，这 个图形的周长是多少？ 3、有一块长方形广场，沿着它不同的两条边各划出2米做绿化带，剩下的部分仍是长方形，且周长为280米。求划去的绿化带的面积是多少平方米？ 【例题3】 已知下图中，甲是正方形，乙是长方形，整个图形的周长是多少？ 【思路导航】从图中可以看出，整个图形的周长由六条线段围成，其中三条横着，三条竖着。三条横着的线段和是（a＋b）×2，三条竖着的线段和是b×2。所以，整个图形的周长是（a＋b）×2＋b×2，即2a＋4b。 练习3

小学数学知识点汇总以及题型归纳整理
小学数学知识点汇总 一．整数和小数 1．最小的一位数是1，最小的自然数是0 2．小数的意义：把整数“1”平均分成10份、100份、1000份……这样的一份或几份分别是十分之几、百分之几、千分之几……可以用小数来表示。 3．小数点左边依次是整数部分，小数点右边是小数部分，依次是十分位、百分位、千分位…… 4．小数的分类：小数有限小数 无限循环小数 无限小数{ 无限不循环小数 5．整数和小数都是按照十进制计数法写出的数。 6．小数的性质：小数的末尾添上0或者去掉0，小数的大小不变。 7．小数点向右移动一位、二位、三位……原来的数分别扩大10倍、100倍、1000倍…… 小数点向左移动一位、二位、三位……原来的数分别缩小10倍、100倍、1000倍…… 二．数的整除 1．整除：整数a除以整数b（b≠0），除得的商正好是整数而且没有余数，我们就说a能被b整除，或者说b能整除a。 2．约数、倍数：如果数a能被数b整除，a就叫做b的倍数，b就叫做a的约数。 3．一个数倍数的个数是无限的，最小的倍数是它本身，没有最大的倍数。 一个数约数的个数是有限的，最小的约数是1，最大的约数是它本身。 4．按能否被2整除，非0的自然数分成偶数和奇数两类，能被2整除的数叫做偶数，不能被2整除的数叫做奇数。5．按一个数约数的个数，非0自然数可分为1、质数、合数三类。 质数：一个数，如果只有1和它本身两个约数，这样的数叫做质数。质数都有2个约数。 合数：一个数，如果除了1和它本身还有别的约数，这样的数叫做合数。合数至少有3个约数。 最小的质数是2，最小的合数是4 1~20以内的质数有：2、3、5、7、11、13、17、19 1~20以内的合数有“4、6、8、9、10、12、14、15、16、18 6．能被2整除的数的特征：个位上是0、2、4、6、8的数，都能被2整除。 能被5整除的数的特征：个位上是0或者5的数，都能被5整除。 能被3整除的数的特征：一个数的各位上数的和能被3整除，这个数就能被3整除。 7．质因数：如果一个自然数的因数是质数，这个因数就叫做这个自然数的质因数。 8．分解质因数：把一个合数用质因数相乘的形式表示出来，叫做分解质因数。 9．公约数、公倍数：几个数公有的约数，叫做这几个数的公约数；其中最大的一个，叫做这几个数的最大公约数。 几个数公有的倍数，叫做这几个数的公倍数；其中最小的一个，叫做这几个数的最小公倍数。 10．一般关系的两个数的最大公约数、最小公倍数用短除法来求；互质关系的两个数最大公约数是1，最小公倍数是两数之积；倍数关系的两个数的最大公约数是小数，最小公倍数是大数。 11．互质数：公约数只有1的两个数叫做互质数。 12．两数之积等于最小公倍数和最大公约数的积。 三．四则运算 1．一个加数=和-另一个加数被减数=差+减数减数=被减数-差 一个因数=积÷另一个因数被除数=商×除数除数=被除数÷商 2．在四则运算中，加、减法叫做第一级运算，乘、除法叫做第二级运算。
