Students are very interested in the clay bowl, and they can't wait to try it when they see the materials sent by the teacher. As a result, a few students didn't listen carefully in the process of observing the pictures and explaining the steps under the guidance of the teacher, and they were in a hurry during the production process, but it was normal, because after all, children have fewer opportunities to practice now. After the expansion, students expressed more interest and had a good influence on them.

2022 Labor Teaching Plan 2 Activity Objectives:

1. You should know that May 1 is International Labor Day, which is a holiday for all working people.

It is a hard and happy thing to know the labor of people from all walks of life and experience it.

3. Stimulate children's desire to love labor.

4. Let the children know the origin of the festival, feel the atmosphere of the festival and celebrate the festival together.

5. Experience obvious seasonal characteristics.

Activity preparation:

On holidays, arrange children to go to a nearby barber shop for a haircut, go shopping in the supermarket and learn about other people's labor.

Activity flow:

1. Teacher introduced that May 1 is the International Labor Day, which is a festival for all working people.

2. Let the children recall their experiences in barbershops and supermarkets, and learn more about the hard work of the staff in these places.

The teacher asked: What do you see in these places? How do they work?

3, children's discussion, to help children further understand that labor is a hard and happy thing.

Question: What do uncles and aunts in barbershops do? What would happen without them? Are uncles and aunts tired of standing in the supermarket every day? Why do you have to do it when you are tired? What do you think of their mood? Why?

4. Lead children to participate in kindergarten public welfare labor (picking stones, picking leaves, sweeping the floor), and observe the cleanliness of the venue after work, so that children can further experience the hard work and happiness.

Teaching reflection:

There are many festivals in a year, and May Day is coming. With the growth of children, combined with their age characteristics and love ability, children can understand and know how to respect the work of others. Contact the actual situation of kindergarten, let children go out of kindergarten, step into society, actively participate in public social activities, cultivate children to know how to care about people and things around them from an early age, and improve their sense of responsibility and social adaptability.

Teaching objectives of labor teaching plan 3 in 2022:

1. Instruct students to learn to nail buttons, and educate them to do it themselves and master hand sewing skills.

2. Pay attention to safety while enjoying the pleasure of working.

Teaching emphases and difficulties:

Key points: learn to nail the double eye button and the four eye button.

Difficulties: threading the needle.

Teaching preparation:

Teacher preparation: warm tips, evaluation criteria, extended printed materials; Physical projector

Students prepare: needle, thread, cloth (or handkerchief), scissors and (double, four) eye buttons.

Teaching process:

(A) the introduction of new curriculum learning materials

Students, in our daily life, whenever our farm clothes are broken, our buttons fall off and our schoolbags crack, what should we do? Who did these things for you? Do you want to learn to button yourself?

Today, we will learn to nail buttons in this class.

(2) explain the production method

1. Slide show: various buttons. How to classify them?

2. Blackboard projection:

From buttonholes: buttonholes with one eye, buttonholes with two eyes and buttonholes with four eyes.

The types of buttons are divided into square buttons and round buttons.

From the texture: plexiglass buckle, metal buckle, electroplated plastic buckle.

3. Talk about the nail method of different buttons. Focus on the nail method of double eye button and four eye button (see picture on page 27).

(1) Binocular nail buckle.

① Needle threading: Cut a thread slightly longer than the arm, twist the thread end sharply and straight by hand, then thread the thread end into the eye of the needle and tie a knot at the other end of the thread.

(2) After determining the position of the button, pinch the button together with the cloth with your left hand to prevent it from shifting. Thread the needle through one hole of the button from the back of the cloth, and then thread it through the other hole of the button to tighten the thread on the back of the cloth. Repeat this method four or five times, fix the button on the cloth, then tie the knot and cut the thread. (Focus on guiding the knotting method)

(2) Nail four-eye buttons.

The first type: cross nail.

Nailing is similar to nailing double eyes. Just go through it (see picture on page 27).

The second type: "two-shaped" nail method.

There is only one difference from the cross nailing method, that is, the stitches on the front of the button should be nailed in a "two-shaped" shape and cannot be crossed (see picture on page 27).

(3) Students practice in groups and teachers patrol.

1. Teamwork, teaching and learning from each other.

2. The physical projector shows the process of students tying the needle and tying the knot.

I learned the basic method of nailing buttons. Think about it. Are there any other manicure methods?

4. How to fasten other buttons? Show me different styles of buttons and tell me what you use.

Methods Nail (read supplementary materials).

5. What else do you need to pay attention to when nailing buttons on clothes?

(1) The position of the button should be aligned with the buttonhole on the clothes, which can be marked with special chalk (see No. 12

Pictures on the page).

(2) After the needle is inserted, lift the needle and thread upward, and don't pull it sideways, so as not to poke others with the needle tip.

(4) Exhibition and interactive evaluation of works

1. Review in groups and fill in "∞" in the notebook.

2. Show excellent works and talk about the process of nailing buttons and matters needing attention.

(5) Reviewing and enlightening innovation.

Summary: The students have mastered the basic method of nailing buttons. The teacher believes that in the future, if you drop the button, you can nail it yourself. Develop your own things and good habits from an early age.

Write a short article about the process of nailing buttons and communicate in class.

Blackboard design:

Start needle-end needle

Teaching reflection:

1. It is also a way to train students to explore thinking when giving them a "magic weapon" (auxiliary thread for needle threading). I gave instructions too early in class.

2. Put the grade evaluation standard before students nail the second button, maybe the quality of students' works will be better.

3. Every time you assign homework tasks, you should give students time, which can not only improve classroom efficiency, but also facilitate students to form habits and make teachers master the classroom easily.
