first kind
First, the introduction of dialogue to stimulate interest
1. Introduction: Children, autumn is the season when plant seeds mature. The seed baby is going to bid farewell to his mother and start his own life. Want to know what good way plant mothers say goodbye to their children? Today, we are going to learn "Mother Plant has an idea". Write on the blackboard.
6. Look at the topic together: Know that "plant mother" and "child" refer to plants and their seeds respectively.
3. Courseware demonstration: Play the animation of dandelion, Xanthium sibiricum and other plants spreading seeds to guide students to observe. Today, the lesson "Mother Plant has a way" will tell us the ingenious ways for plants to spread seeds. Now let's learn. Write on the blackboard.
Second, check the preview, the first reading perception.
1. Read the text freely, and read the unknown words several times with the help of pinyin. ("Wei, De" is a disyllabic word)
Read aloud to each other in groups and tell me what you have read.
3. Cooperation and exchange:
(1) Sketch communication: Which plant mothers spread seeds in the text?
(2) How many bars does this poet have? Write the following in each section?
Section 1: Put forward how plants spread seeds.
Section 2: Talk about the method of dandelion spreading seeds.
Section III: Talking about the spreading methods of Xanthium sibiricum seeds.
Section 4: Talk about the method of pea spreading seeds.
Part V: It is pointed out that a lot of knowledge can be gained through careful observation.
4. Teacher: The Poetry of * * * has five sections, which are developed according to the idea of "asking questions-introducing them in detail-prompting observation". The first section stimulates students to think: what methods do plants use to spread seeds; The second, third and fourth sections describe the methods of spreading seeds by Taraxacum mongolicum, Xanthium sibiricum and Pistacia tonkinensis respectively. The fifth part encourages students to observe carefully and discover new knowledge.
Third, remember new words and understand them.
1. Show 14 new words and teach yourself to read in pinyin.
4. Read in many ways. (Focus on the accurate pronunciation of the disyllabic word "Wei, De", and emphasize the definition of pronunciation according to the meaning in the specific context. )
3. Communicative Literacy: What method did I use to remember which word?
Practice reading with the words "plants, if, cosmopolitan, traveling, preparing, swarming, stinging, underground, blasting, leaving, observing, knowledge, carelessness, not getting".
Students are not familiar with "De (dé), preparation, stabbing and observing", so they should read the words "De (děi), De (dé), preparation, stabbing and observing" more. And consolidate pronunciation in the new context, such as reading "must, have, can", "get, feel, be proud", "jump high, look beautiful, write well", "prepare lessons, be complete, spare", "fishbone, small thorn, harsh", "bottom, bottom" and "look, feel, feel.
Correctly read "knowledge, cognition and insight" and then read "literacy, cognition and common sense".
4. Practice oral word formation.
Fourth, guide writing.
1. Focus on guiding "it, baby and more". Write the lower part of "it" first, and then write the vertical hook; The right side of the "baby" consists of two "earths"; The sixth stroke of "Geng" is skimming.
2. Focus on guiding the component composition of "feet". Emphasize that the "foot" is next to the single ear, and the single ear is hooked vertically (both ears are hooked vertically). "Foot" pays attention to writing at will; Both "foot" and "law" have "flexion", but they are different in size. The reason why "Zu" is small is that "Zu" consists of three parts, with many strokes, while "Qu" is bigger than "Fa".
3. The strokes are different in length and density, and the "baby" should pay attention to how far and how far, and the length is different; "Ru" and "Wa, She" are both beside the women's book, because on the right side of "Ru" is the "Kou" with few strokes, short vertical strokes and square shape, so the women's book is larger; Both "Ru" and "Zhi" have mouths on the right, but the writing of the mouth on the right is slightly different from that on the left: the mouth on the left is small in the middle, such as "scare, yeah", and the mouth on the right is slightly larger in the middle.
4. Practice writing new words, and the teacher will patrol the classroom to see if the stroke order and writing posture are correct.
