Class arrangement

2 class hours

teaching process

first kind

First, introduce the new curriculum and reveal the theme.

Paper-making, printing, compass and gunpowder are four great inventions in ancient China, and they are great contributions made by our working people to the progress of world civilization. There was no paper in ancient times. Shang dynasty carved characters on tortoise shell bones, which is the earliest ancient prose. During the Zhou Dynasty, people used bamboo slips (that is, bamboo pieces), wooden slips and silk books. During the Western Han Dynasty, working people invented making paper with silk wadding, and later made paper with hemp fiber. In the first year of Yuan Xing in the Eastern Han Dynasty (AD 105), eunuch Cai Lun used bark, hemp head, rags and old fishing nets as raw materials to improve papermaking. Since then, the output of paper has greatly increased. During the Tang Dynasty, papermaking began to spread abroad to Korea, Japan, Arabia, Europe and other places.

Second, word learning, basic accumulation

1. With the help of reference books, get familiar with radical search and find out the pronunciation and meaning of new words.

(1) Determine the radicals of new words and learn the radical method.

(2) Take the word "Hao" as an example to explain the radical search method, and the students will follow suit.

Key points: radical directory → radical pictures (radicals) → word lookup table → radicals → statistics of pictures other than radicals → finding page numbers of corresponding words → dictionary text.

(3) Oral induction: check the top but not the bottom, check the left and not the right, check the outer circumference, and check the pen with single words.

2. Write a description of the words that can be written.

Writing instruction:

Wei is narrow on the left and wide on the right. The third picture "Wei" on the right is a cross hook.

The density of the book should be uniform around, and the first picture and the third picture of the book are vertical.

The first and third strokes of "save" should be written shorter.

Error-prone tips:

The radical of "she" is "you" rather than "you".

3. Polysyllabic words.

Tired léi: cumbersome léI: piled léI: tired.

Fresh xiān: vivid Xi m m ∥ n: little known.

4. Understand the following words.

Creation: Inventing and manufacturing things that have never been seen before.

(Example: The Chinese nation has created glorious history. )

Carving: Carving and casting characters on metal.

(Example: The words carved on the bronze ware are called inscriptions on bronze. )

Carry-on: Carry-on.

(Example: Pets are not allowed in the library. )

Cocoon: an oval shell formed by silkworms spinning silk, in which silkworms become pupae.

(Example: Cocoon is the raw material of textile silk. )

Bamboo mat: a mat woven with bamboo mats.

(Example: It's cool to lie on the sofa in summer. )

Second, text learning, breaking through difficulties

1. Read the text freely and think: Before the invention of paper, what did people use to record words?

Clear: it is made of hemp. In the Western Han Dynasty, people already knew how to make paper with hemp, but hemp paper was rough and difficult to write.

3. How did Cai Lun transform hemp paper in the Western Han Dynasty?

Qing: Cai Lun absorbed long-term accumulated experience, cut or chopped bark, hemp, straw, rags and other raw materials, soaked them in water, mashed them into pulp, and then fished out the pulp and dried it in the sun, making it a light and easy-to-use paper.

4. Why can Cai Lun's improved papers be handed down?

Mingque: Cai Lun's improved paper, with easily available raw materials, can be manufactured in large quantities and low price, can meet the needs of most people.
