Pronunciation: "greedy", "spoon" and "silly" are rolled tongue sounds, while "secondary" and "pale" are flat tongue sounds. "Soup" is nasal.

Glyph: the word "nine" of the word "dye" should not be too many, and it should be written as "pill"; The word "true" for "filling" has three horizontal lines.

(2) Reread the text to consolidate the identification.

4. Say one thing in the text.

With students as the main body, teachers put forward requirements. Read by yourself and answer the questions. And in the collective exchange feedback, teacher-student interaction learning to test the learning situation, consolidate the cognition of the new words in this article, and grasp the content of the text as a whole.

Teaching preparation:

Calculator, small blackboard with chessboard.

Teaching time:

2 class hours

Teaching process:

first kind

First, the introduction of mathematical games.

1, the kingdom of mathematics is a fascinating magical kingdom. Let's walk into the kingdom of mathematics today and play an interesting math game. Would you like to have a try?

2. Show a small blackboard with Indian chessboard and introduce relevant knowledge: Indian chess chessboard is square, with 8 rows horizontally and vertically, with a total of 64 squares, and the pieces are placed in the middle of the squares. Among them, the dark grid is called Haig, and the bright grid is called white grid. There are 32 black and white grids, which are staggered.

3. The teacher introduced the rules of the game: Please fill in 2 in the first box, 4 in the second box, 8 in the third box, and so on. Every time you move forward to the last box, multiply the previous number by 2. Please make a preliminary estimate. When you fill in the last box, what is the approximate number? See who estimates the number closest to the correct answer.

4. The teacher writes representative figures on the blackboard according to the students' estimation results.

5. Check whether the estimate is correct: Let the students take out their calculators and calculate quickly (in pairs, one will calculate and the other will fill in the numbers in the box). At the same time, please ask two students to go to the stage to calculate and fill in.

6. Students report the calculation results. By the time the fourth row is in the eighth box, the number has reached 4294967296, and the number behind it is too big for the calculator to calculate. )

7. The teacher fills in 4294967296 in the corresponding box. Please read this number. (4,294,967,296)

Teacher: I really don't know. I was shocked. When I filled in the 64th box, we couldn't imagine what astronomical figure it was. Do you think this number is too big for a calculator to calculate? Can you describe the feeling when you see this astronomical figure in one sentence?

8. This involves a math problem you will learn in junior high school: the power of 2. There is a little girl named Chandra in India (writing on the blackboard: Chandra, the camera guides her to learn the word "Chandra". She liked math since she was a child and found that multiplying by two would get an amazing astronomical figure. She skillfully used this rule to do a good thing for the villagers. Do you want to know this interesting story? Chandra's wisdom lies in the text we are going to learn today.

9. Write the questions on the blackboard and read the questions together.

10, what do you want to know when you see the topic?

1 1, the camera combs the questions raised by the students.

Second, third, read and understand the text.

1. Read the text for the first time and solve some simple questions: Read the text once, can you answer which question you just asked?

2. The second reading, requirements: who to read the pronunciation with, draw words with new words, read independently (can communicate quietly with the deskmate), and read the text.

3. Exchange memory methods.

4. Guide writing.

"Dye": Don't write "nine" on it as "pill".

"Fill in": the right side is "true", and there are three horizontal lines in the box to prevent it from being written as two horizontal lines.

5. Read the text for the third time.

Teacher: Let's have a reading contest to see who reads the most accurately, fluently and emotionally. The student who reads best will be our champion today. Do you want to read the text again for your wonderful performance in the competition? Pay attention to reading and thinking, reproduce the chessboard in your mind, try to understand the text, and read it several times if you don't understand it.

Carry out a reading contest, the teacher will guide the evaluation and select the "champion".

Third, homework.

Copy words.

Second lesson

First, explore the text.

1. Found a problem. Encourage students to read the text carefully and ask interesting or difficult questions.

Preset: ① How many meters does it take to fill a whole chessboard? (2) Really, as Chandra said, "Will all the land in India be buried knee-deep by these meters at the last square of the chessboard?"

2. Explore questions around doubts.

When the fourth row of the chessboard is full of rice, what is the measured value? (trolley)

So, now let's do an interesting math problem. Let's start from the fourth row and calculate by the unit of "cart" to see how many cart meters are needed to fill a whole chessboard. (When the last grid in the seventh row is calculated, guide the students to deduce 4294967296 car meters according to the calculus in the last class. )

The population of China exceeds 654.38+03 billion. Think about it. If all the 654.38+03 billion people in China are dispatched to transport this part of rice, do you know how many cars each person needs to transport? (More than three cars) And this is only the rice in the seventh row. If we count the last box of the eighth box, then each of us in China will have to transport at least 800 cars.

3. Look at the quantity of rice from the change of quantifiers.

◆ Find out the unit of measurement for calculating rice from the text.

(blackboard writing: particles → spoons → bowls → cars ...)

◆ What have you learned from the change of measurement units?

◆ Imagine: If there is enough rice in India, when the servant counts to the last few rows, can he still count with a trolley? What do you think may be needed for the calculation? (trucks, ships, trains ...)

4. Grasp the expression and experience the characters' psychology.

△ Find out the expressions of villagers, servants and princes from the text;

Villagers: shake your head straight → smile.

Servant: Laughing → I don't know how to count princes: I am secretly happy → I struggle to stand up.

△ Imagine psychological activities from their expression changes. Demonstration exercise: When Chandra asked the servant to put 2 grains of rice in the first box, 4 grains of rice in the second box and 8 grains of rice in the third box ... The villagers shook their heads at her choice and thought: ()

The servants smiled and thought: ()

The maharaja was secretly happy and thought: ()

Second, expand and extend.

1. Why did Chandra do this? Why did she come up with such a clever idea?

Besides, what kind of person do you think Chandra is? Where can I tell? For example, she is kind-hearted and cares about elephants. From the contrast that seven veterinarians failed to cure the elephant, but she was able to cure it, we can see that she is not constrained by conventional thinking, good at observation and good at finding problems. )

Third, homework.

1. Tell this story to your family.

2. Collect interesting math stories or math puzzles and prepare to hold "Smart Paradise" class activities.

Blackboard design:

Indian maharaja's rice

Particles → spoon → bowl → car … Chandra.

Villagers: shake your head straight → smile (smart and kind)

Servant: Laughter → I don't know how to calculate.

Maharaja: secretly happy → struggling to stand up.
