比和比例应用题。

教学内容

教材第85-86页

教学目标

1、掌握比和比例应用题的结构特征和解题思路，能应用知识解决一些简单的实际问题。

2、培养学生运用知识进行分析、推理等思维能力，体会和掌握数形结合的思想.

3、沟通知识间的联系,激发学生的学习兴趣,培养学生的合作意识.

教学重点

掌握比和比例应用题的结构特征和解题思路。

教学难点

正确判断正反比例关系.

教学准备

PPT

教学过程：

一、准备过程：

1、解方程：38:X=0.5×19

2÷x3=0.5

2、判断下面各题中的两种量是否成比例,成什么比例?

①长方形的宽一定,它的面积和长.

②吴刚的身高和年龄.

③从甲地到乙地,所用的时间和速度.

回忆：⑴什么叫成正比例的量和正比例关系？

⑵什么叫成反比例的量和反比例关系？

⑶比较正、反比例的相同点和不同点，完成下表。

相同点

不同点

关系式

正比例

反比例

⑷如何判断两种量是否成正比例或反比例的？

通过交流，概括出“一找、二想、三判断”，即：

一找：哪两种相关联的量。二想：两种相关量的变化情况，写出关系式。三判断：根据关系式，看是商一定还是积一定，判断成什么比例。

二、梳理知识,形成网络.

1.

知识梳理：

①我们小学阶段学到了哪些基本性质？

②有关比与比例的应用题有哪几个类型?

③关于比与比例的应用题你对大家有哪些提醒？

2.

形成网络:（1）分数和小数的基本性质，比和比例的基本性质，商不变的规律，等式的性质。

（2）比与比例的应用题可分为比例尺的应用题、按比分配应用题、正反比例应用题等.

比例尺的应用题：

①知图上距离与实际距离，求比例尺

关系式：图上距离：实际距离=比例尺

②已知比例尺与实际距离，求图上距离

关系式：实际距离×比例尺=图上距离

③知图上距离与比例尺，求实际距离

关系式：图上距离：比例尺=实际距离

按比分配应用题：

一般解题方法：①求出总份数----求出一份数-----求几份数

②转化成分数应用题：求各部分量占总数量的几分之几-------求总数量的几分之几是多少。

正反比例应用题：

解答方法：①分析数量关系。判断题目中的两种量成什么比例。②找等量关系。如果成正比例，则按“等比”找等量关系，如果成反比例，则按“等积”找等量关系。

③列方程并解答，并检验。

三.巩固练习：

（1）填空：①0.25=2（）=（

）：12=4÷（

）=（

）％。

②0.375：94化成最简整数比是（

），比值是（

）。

③若A:B=3:2，当A=2时。要使等式成立，B应是（

）。

④把一根粗细均匀的木头锯成3段需6分钟，照这样计算，锯成6段需（

）分钟。

⑥一个三角形三个内角的度数比是2:1:1,这是一个（

）三角形。⑦如果图上距离40厘米表示实际距离2千米，那么这幅图的比例尺是（

）；若在这幅地图上量得甲、乙两地的距离是6.4厘米，那么甲、乙两地的实际距离是（

）。

（2）判断：

①在一个比例中，如果两内项互为倒数，那么两外项一定成正比例。（

）

②3:8的前项加上9，后项应乘3才能使比值不变。（

）

③因为5a=6b（a、b不为0），所以a：b=6:5。

（

Jubilee was named after a baby chimpanzee in the London Zoo. This seemed to predict the course Jane’s life would take. To this day, Jubilee sits in a chair in Jane’s London home.From an early age, Jane was very interested in 37 and animal stories. By the age of 10, she was talking about going to Africa to live among the animals there. At the time, in the early 1940s, this was almost impossible 38 women did not go to Africa by themselves.As a 39 woman, Jane finished school in London, and then worked for a filmmaker for a while. When a school friend invited her to visit Kenya, she took another 40 until she made enough money to 41 there by boat. She was 23 years old.Once in Kenya, she met Dr. Louis Leakey. He was surprised at her 42 of Africa and its wildlife. He soon realized that Jane was the 43 person to complete the study he had been planning for some time. She expressed her 44 in the idea of studying animals by living in the wild with them, rather than 45 dead animals.Dr. Leakey and Jane 46 planning a study of a group of chimpanzees who were living on the shores of Lake Tanganyika in Kenya. At first, the British government did not pass their plan. At the time, they thought it was too dangerous for a woman to live in the wilds of Africa 47 . But Jane’s mother, Vanne, agreed to join her so that she would not be alone. Finally, the government changed their mind. She was able to go to Africa and begin her study.36.

The passage is ______.A. a piece of news B. an advertisementC. a business letter D. an interviewBLong ago, there was a young poor boy. He had no family. He only had an old camel. Each day the boy and his camel walked many miles looking for a home. Each night they stayed together and slept in the open air. But one evening, the old camel died. The boy sat there under a tree and cried. What would he do? He had no family and no home.The boy cried for a very long time. But there was no one to talk to. There were only the stars in the sky.Suddenly, the sky filled with bright light. The boy held his breath. He was afraid to move. One bright star fell to the ground. Slowly, the star took the shape of the old camel. She looked at the boy and smiled. As she jumped back into the sky, bits of camel wool fell.As the sun began to rise, the boy picked up the soft, warm wool. He carried the wool to the city and sold it. With the money, he bought a house. He bought two young camels. He never forgot the star camel. And he was never lonely again.51.

What can we learn from the story?A. The boy was lazy and stupid. B. The old camel came back to life.C. The boy lived happily in the end. D. The old camel changed into stars.CJames Naismith, a physical education teacher in Massachusetts, invented basketball in 1891. Naismith’s boss asked him to invent a game that students could play indoors during bad weather. He wanted to find a game that wasn’t as rough as soccer or football.Naismith tied apple baskets to a railing (铁棍) ten feet above the floor at either end of the gym. The players used a soccer ball.A person sat on a ladder next to each basket at either end of the gym, and threw out the balls that landed in the baskets. To keep t he game from getting too rough, Naismith decided each team would have only five players and that the players could not play the ball with their feet.Two years later, net bags were used instead of baskets. In 1894, Naismith added the backboard behind each net and changed to a larger ball. In 1913, people began using the bottomless nets that are used today.During a basketball game, two teams of five players each throw the ball into two baskets at opposite ends of a court. Players bounce, or dribble the ball to the basket or pass the ball to teammates. A team scores points by getting the ball into their team’s basket. The team with the highest score wins.By the 1900s, basketball was the most popular indoor sport. People in nearly 130 countries play the game. Basketball is especially popular in the United States, China, and Puerto Rico.54. When did people start to use a basketball?A. In 1891. B. In 1894. C. In 1913. D. In 1900s.55. What does the underlined word “rough” probably mean?A. Boring. B. Popular. C. Hard. D. Quick.56. Which of the following can be the best title of the passage?A. The Invention of a Popular Game B. The Rules of the Old BasketballC. What Naismith Found Indoors D. Why People Loved SportsDYou have learned about energy. Do you know that HEAT is a form of ENERGY? Yep, this form of energy acts on everything. And, we’re going to look at a few experiments to learn how this form of energy acts and why we need to know all about it.The heat energy of something is decided by how active its atoms(原子)and molecules(分子)are. A hot object is one whose atoms and molecules are excited and show rapid movement. A cooler object’s molecules and atoms will be less excited and show less move ment. When these guys are in the excited state, they take up a lot of space because they’re moving around so fast. When the atoms and molecules settle down, or cool down, they take up less space.If a HOT high-energy atom comes into contact with a cool low-energy atom, the excited atom will loose some of its energy to the cool atom. The two atoms will reach an ener gy level that’s betwe en where they each started out. That level is called Thermal Equilibrium.Experiment: If you have a cup of really hot chocolate and want to cool it down, you may put an ice cube in the cup. After the ice has completely melted (disappeared), the hot chocolate and the melted ice have come to Thermal Equilibrium.Now that you have an idea of what heat is, let’s look at some of the effects of this form of energy. Here’s another experiment. Blow up a balloon, but not all the way. Put the balloon in a refrigerator for about an hour, then take it out. Did it become smaller? Why?It became smaller because the air molecules inside the balloon slowed down and are taking up less space. Now put the balloon in direct sunlight. What happened after it warmed up? Why?From the above experiment, we learned a very important fact—heat causes things to “grow”. We call this Thermal Expansion. If things “grow” when heated, what do you think happens to them when they get cold?If you get a chance to check out some railroad tracks, notice the gaps or separations between the rails. (Don’t get run over by a train!) Thermal expansion and contraction is why those gaps are placed there that way, and why expansion joints are placed in long highway bridges.
