比和比例應用題。

教學內容

教材第85-86頁

教學目標

1、掌握比和比例應用題的結構特征和解題思路,能應用知識解決一些簡單的實際問題。

2、培養學生運用知識進行分析、推理等思維能力,體會和掌握數形結合的思想.

3、溝通知識間的聯系,激發學生的學習興趣,培養學生的合作意識.

教學重點

掌握比和比例應用題的結構特征和解題思路。

教學難點

正確判斷正反比例關系.

教學準備

PPT

教學過程:

一、準備過程:

1、解方程:38:X=0.5×19

2÷x3=0.5

2、判斷下面各題中的兩種量是否成比例,成什么比例?

①長方形的寬一定,它的面積和長.

②吳剛的身高和年齡.

③從甲地到乙地,所用的時間和速度.

回憶:⑴什么叫成正比例的量和正比例關系?

⑵什么叫成反比例的量和反比例關系?

⑶比較正、反比例的相同點和不同點,完成下表。

相同點

不同點

關系式

正比例

反比例

⑷如何判斷兩種量是否成正比例或反比例的?

通過交流,概括出“一找、二想、三判斷”,即:

一找:哪兩種相關聯的量。二想:兩種相關量的變化情況,寫出關系式。三判斷:根據關系式,看是商一定還是積一定,判斷成什么比例。

二、梳理知識,形成網絡.

1.

知識梳理:

①我們小學階段學到了哪些基本性質?

②有關比與比例的應用題有哪幾個類型?

③關于比與比例的應用題你對大家有哪些提醒?

2.

形成網絡:(1)分數和小數的基本性質,比和比例的基本性質,商不變的規律,等式的性質。

(2)比與比例的應用題可分為比例尺的應用題、按比分配應用題、正反比例應用題等.

比例尺的應用題:

①知圖上距離與實際距離,求比例尺

關系式:圖上距離:實際距離=比例尺

②已知比例尺與實際距離,求圖上距離

關系式:實際距離×比例尺=圖上距離

③知圖上距離與比例尺,求實際距離

關系式:圖上距離:比例尺=實際距離

按比分配應用題:

一般解題方法:①求出總份數----求出一份數-----求幾份數

②轉化成分數應用題:求各部分量占總數量的幾分之幾-------求總數量的幾分之幾是多少。

正反比例應用題:

解答方法:①分析數量關系。判斷題目中的兩種量成什么比例。②找等量關系。如果成正比例,則按“等比”找等量關系,如果成反比例,則按“等積”找等量關系。

③列方程并解答,并檢驗。

三.鞏固練習:

(1)填空:①0.25=2()=(

):12=4÷(

)=(

)%。

②0.375:94化成最簡整數比是(

),比值是(

)。

③若A:B=3:2,當A=2時。要使等式成立,B應是(

)。

④把一根粗細均勻的木頭鋸成3段需6分鐘,照這樣計算,鋸成6段需(

)分鐘。

⑥一個三角形三個內角的度數比是2:1:1,這是一個(

)三角形。⑦如果圖上距離40厘米表示實際距離2千米,那么這幅圖的比例尺是(

);若在這幅地圖上量得甲、乙兩地的距離是6.4厘米,那么甲、乙兩地的實際距離是(

)。

(2)判斷:

①在一個比例中,如果兩內項互為倒數,那么兩外項一定成正比例。(

②3:8的前項加上9,后項應乘3才能使比值不變。(

③因為5a=6b(a、b不為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. When the old camel died, the boy cried because ______.A. he was afraid B. he was poorC. he was lonely D. he was lost52. What happened first in the story?A. The boy bought two new camels.B. The boy collected the wool and sold it in the city.C. The star fell to the ground in the shape of the old camel.D. The boy and the camel walked many miles looking for a home.53. 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 (鐵棍) 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. You’ve probably felt expansion joints on old concrete highways. Remember the “thump–thump” sound as you rode over them?57. How many experiments are mentioned in the passage?A. Two. B. Three. C. Four. D. Five.58. What is Thermal Equilibrium?A. The fact that hot atoms loose some energy to cool atoms when they meet.B. The fact that there are always the gaps or separations between the rails.C. The fact that heat causes things to increase in size.D. The fact that heat is another form of energy.59. Why is the first paragraph written?A. To explain what heat energy is. B. To sort energy forms for readers.C. To gi ve examples of heat energy. D. To tell readers what to read here.60. What is the last paragraph mainly about?A.
