Middle school mathematics variable graphics teaching plan

As an educator who teaches others, he often has to write lesson plans according to the teaching needs. With the help of teaching plans, the teaching quality can be improved and the expected teaching effect can be achieved. What are the characteristics of excellent lesson plans? The following is a graphic teaching plan for middle school students, which I carefully arranged, hoping to help everyone.

Middle school mathematics 1 activity target variable graphics teaching plan;

1, in the repeated changes of graphics, train children's thinking and improve their operational ability.

2. By making children change triangles, squares, trapezoids, circles and other figures repeatedly, guide children to find that the figures can change and transform with each other, and can be changed into different numbers of various figures.

3. Cultivate children's interest in combining various graphics into various objects.

4. Stimulate children's interest in learning graphics.

5. Develop children's logical thinking ability.

Activity preparation:

1. Teaching aid: triangle, rectangle, trapezoid and circle are combined into a picture (robot).

2. Learning tools: each person has a set of paper with various graphics and puts it in an envelope.

Activity flow:

(1) Beginning: Little friend, do you know what the teacher is holding? (The teacher takes out a wall chart with his back to the child), change it! An art exhibition appeared in front of the children. "Robot" Yes! Then look at what robots are made of. "Made of graphics." All right! Let's play a game about graphics.

(2) Basic part: the first attempt: observation and thinking.

L, let the children use their brains and carefully observe what graphics the robot is made of? It consists of a circle, a square, a triangle, a rectangle and a trapezoid. )

2. How many numbers are there in each type? (6 circles, 6 semicircles, 1 square, 4 rectangles, 5 trapezoids and 1 triangle. The second attempt: use origami game to see the change of graphics.

1. Gift: (Learning tool) Children, everyone has done well in the above games, and the teacher should reward them. Every child has a gift (school supplies). I know everyone wants to see what presents are in the bag. Ok, please open the small envelope yourself (there are many colors of graphics in it). Do you like it? ("I like it!" ) these small numbers are still amazing. If you fold them by hand, they will become other shapes. Try it if you don't believe me.

2, operation: use your hands and brains to perceive the graphic transformation.

(1) Let the children make a change by hand (origami). (2) Let the children talk about the result of change: a square-a triangle and a rectangle. Round-semi-circular, fan-shaped. Rectangular-into triangles and squares.

(3) Conclusion:

Multicolored graphics are full of fun: Are these little graphics interesting, children? (fun! ) Then if we stick it on white paper, it will become a beautiful sticker. Give these photos to your parents. Teachers and students enjoy the joy of hand-making.

End of activity:

Let the children go home and find out with their parents which things in your home are the graphics you know.

Graphic teaching plan of variable mathematics in Grade 2 [content analysis]

Children's innovative wisdom game is a new course with the goal of cultivating children's innovative spirit and making them have initial innovative consciousness. The content of the textbook itself comes from life, especially from what happens around children, that is, paying attention to making children pay more attention to things around them. Cultivate children's innovative spirit and quality of bold imagination and exploration through their own attempts and experiences. The activity of "changing graphics" comes from the design of the textbook itself. Taking teaching materials as the carrier, fully tap children's life experience. On this basis, through continuous innovation and bold improvement, children's ability to imagine boldly is cultivated, and children are encouraged to practice boldly and dare to try new methods.

[child analysis]

Middle-class children are interested in the things around them, and their language expression is incomplete and they have no opinions. With the guidance and help of teachers, they can also do things well. Therefore, in the activities, provide them with some materials that contain educational goals and are suitable for them, so that children can actively participate and explore, develop their thinking through activities, and encourage them to think from different angles.

[Design concept]

Children like to explore mathematical phenomena in life, and are interested and curious about rectangles, trapezoid, semicircles and ellipses. In order to carry out exploration activities such as sorting out, they make use of their existing experience to make bold associations and creations in life and games. Children also need to further study and discover in various operating hours, so this activity is designed.

[Activity objective]

1, cultivate children's interest in adding pictures to puzzles.

2. Develop children's imagination and creativity.

3. Guide children to draw simple objects through association and show their main features on the basis of understanding geometric figures.

[Activity preparation]

A box, several graphic demonstrations, a graphic mosaic toy for each person, a drawing paper for each person, and crayons.

[Activity Flow]

1, import: listen to the music "find friends" to enter.

2, teaching: the game "Wonderful Box". Teacher: Today, the teacher brought a wonderful box. (Showing the box) Do you want to know what secrets are hidden in it?

A, the teacher reads children's songs: there are many things in the wonderful pocket. Let me touch, touch, touch and see first! What is this?

Take out the picture (circle): What is this? Child: It's round.

The teacher then posted this "circle" on the blackboard and discussed: What else are you looking at? Children's divergent thinking imagination: Big Apple, Sun, etc.

B, the teacher read children's songs again: There are many things in the wonderful pocket, please let a child touch them. After the children touched out the pictures, they discussed them as if they were on the table. (rectangle, square, ellipse, triangle)

Teacher: Let's play another game of "Super Magician".

Pick up a circle, change, "change a different face", and turn what into what? How did it become? (Guide children to learn to add pictures and turn them into other graphics)

4. Guide children to imagine and innovate. Children, do you want to do magic like magicians? The teacher prepared some pictures for the children. Let's ask the children to start designing and creating. See who can design something different from others.

5. Show some children's works on the physical projector and make comments to encourage children's design.

[Activity reflection]

Through this activity, children have a good grasp of graphics, and they can immediately say the name and characteristics of graphics as soon as they see them. Very interested in jigsaw puzzles and drawings, rich in imagination. I can tell what an imaginary object is, and the puzzle is well done. Some children in Cato are not very good. I need to strengthen my practice in this area.

Middle school science teaching plan: exploring the refraction of light

Science teaching plan for kindergarten middle class: exploring the refraction of light

moving target

1. Simply understood as the optical path is reversible in refraction.

2. Cultivate children's interest in scientific exploration through experiments.

Activities to be prepared

1, courseware-illustration: refraction of light

2. Optical area of scientific discovery room.

Activity guidance

1. Teachers and children discuss what light is like.

After the discussion, let the children know that when the temperature of the substance is higher than the ambient temperature, we will see the glow of the hot substance.

Such as: fire, candlelight, incandescent lamp, and the above-mentioned steel, glass, stone and other fiery light.

2. Problem: Light travels in a straight line. What are some common examples in life?

Explain to children:

First, using the straight line propagation of light-three-point straight line plays a key role in shooting and archery;

Secondly, we can judge the position of the object through the straight-line propagation of light and the binocular effect of people.

Third, the carpenter planed a piece of wood with a plane. He planed twice to check whether it was straight. Consciously or unconsciously, he used the linear propagation of light to see whether it was straight from one end of the wood along with his eyes.

Fourth, team alignment: "Align to the right!"

3. Children can freely explore and discover the refraction of light in the optical region.

(1) courseware demonstration: refraction of light

By watching the courseware demonstration, let the children have a preliminary understanding of light refraction.

(2) Experiment: Put chopsticks in water to find out the reason why chopsticks turn a corner in air and water.

Air and water are two different media.

(3) Guide children to actively try to use various materials to carry out experiments in optical areas.

Feel and understand the refraction of light in operation.

(4) Teachers comment on the activities, praise and encourage children who have found something in the exploration.

Let the children talk about what they found in the exploration activities.

Children's operation materials: one hand without buttons, several square buttons (rectangle, triangle, circle) with red, yellow, blue and green color characteristics, with 4 to 8 buttonholes on them, one hand in a marked small basket and the other hand in a glue stick.

Third, the activity process:

An interesting picture import activity

Grandma made a lot of clothes and wanted to open a clothing store, but she couldn't finish it by herself. She wants to cooperate with you to finish it, will you?

Two groups of grandmothers look for buttons (classified by two characteristic signs)

1. Consolidate and distinguish graphics according to two characteristics.

-Let's look for it first. What is missing in grandma's clothes? (button)

Really, there are no buttons on the clothes yet! All kinds of buttons are mixed together, and grandma can't tell the difference when she is old. Are you willing to help her?

(showing the red circle sign): However, grandma has different requirements for everyone. Who can understand what kind of buttons Grandma Xiong wants Mr. Xiong to find? What shape is the red button? Is this ok? Why?

-Summary: Yes! Seeing these two signs means looking for a red round button, and both features must be found correctly before they can be put in.

The first operation: find the button according to two characteristics.

Wait a minute, please pick up your little basket, take a closer look and say softly, "What kind of buttons does Grandma want you to help me find?" Then he looked for it gently and said, "What color and shape button did I find?" How many buttons did you find at the last count? Grandma is old. She can't stand such a loud noise. Let's not disturb her! )

-The teacher gives a tour guide to remind the children to talk while operating.

-the children put the small basin under the chair and began to concentrate on communication: what kind of buttons did you find? How to find it without mistakes and leaks? (Look carefully ...)

Personal note: ×× Are you looking for the red triangle button? Look at the colors and shapes clearly, and you can put them in your own box. Don't take other people's buttons away! Is this the button you are looking for? )

Third, the second operation: sort by quantity.

1. Hands and mouth are in the same position.

-Hey! What's on your button? (dot)

Oh! Xx really look carefully, this dot is the hole where the button is threaded. Take out one and count how many holes there are.

Are they all x's? Count the other buttons!

Find the button with the most holes! Show me the least?

Help grandma sew on the buttons (in reverse order).

-You helped grandma find the button. She is so happy! Would you like to help her sew the buttons on her clothes? Where do I start nailing? How to order buttons? Grandma said that this question is a bit difficult, and only the baby who listens clearly and wants to understand will know.

-(Exhibits 4 to 8): Grandma told us here. Who knows? X x looked so carefully that she must have understood! (Children express themselves freely)

The teacher summed up: the top is 4, representing four buttonholes, and the bottom is 8, representing eight buttonholes. This arrow means slowly, slowly changing, more or less? Yes, more and more. ...

-Take a basket and find a dress of your own. Look at the old lady's request for buttons first, and then pour the buttons out and put them on the table. If you think it over, you can click the button!

The teacher pays attention to the tour: can children click the buttons according to the icons and the order?

-Show individuals and pay attention to evaluation;

Who ordered the buttons of this dress? Here, grandma's request is: Are there more and more holes in the buttons ...? More and more. You are so clever. Thank you!

Who is this murderer? Grandma's demands are increasing ...? The original button queue is wrong, so change it!

four

You are really capable, not only helping grandma find buttons, but also making new clothes. Grandma is so happy! She said, "Thank you for these smart and polite babies. Next time, you are welcome to sell clothes in his clothing store! " What should you say? Teacher: well, we are also happy to help grandma! ) After finishing the work, shall we go out and relax? What should I say to grandma and the teacher?

What do you think this is, children? The teacher put a lot of coins in the piggy bank. Now I invite it out to make friends with the children.

2. Basic part

(1) Children meet "friends".

Coin friends like to make friends with people who handle them gently. Can you do it? Please find a friend in the basket.

Ask questions:

A, what shape is the "friend" you are looking for?

What color is it?

C, what's the pattern on it?

(2) Slide show, where the teacher shows the coins of 50 cents and 1 yuan to the children one by one.

Now, please send your "friend" back to the basket. Let's enlarge these coins.

Know a dime and show it to the children with slides.

Positive questions:

How much is this coin? (5 jiao)

B, what's ahead

Tail question:

Is this the front or the back of the Pentagon? (tail)

B, what pattern is printed on it? (Lotus)

Heads and tails-these are the heads and tails of a dime. Please find the same coin in the basket. (After finding it)

Ask questions:

Please touch it. How do you feel? (hard, round and uneven)

What color is it? What shape is it? (gold, round)

Know 1 yuan and show the children 1 yuan coins with slides.

Positive questions:
