Variable shapes lesson plan for middle school math

1, simple understanding of the phenomenon of refraction in the light of the reversible path.

2. Through experiments, cultivate children's interest in scientific exploration.

Activity Preparation

1, classroom materials - illustration: refraction of light

2, science discovery room optical area.

Activity Guidance

1, the teacher and the children to discuss what light is how to shape

After the discussion, let the children know that when the temperature of the material is higher than the ambient temperature, we see the hot material luminescence.

Such as: fire, candlelight, incandescent light, as well as the aforementioned steel, glass, stone and so on when the red glow.

2, the question: light spreads along a straight line, what are the common examples of life

to explain to young children:

First, the use of light spreads in a straight line ---- three points in a straight line, play a key role in shooting, archery sports;

Second, by the straight-line propagation of light, coupled with the human binocular effect , can judge the position of the object.

Third, the carpenter with a planer planing a strip of wood, planing two to check the planing straight, he is consciously or unconsciously use the straight-line propagation of light, with the eyes from the end of the strip along the strip of wood to see that it is not straight.

Fourth, line alignment: "Look right!"

3. Children are free to explore and discover the refraction of light in the optical area.

(1) classroom demonstration: the refraction of light

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

(2) Experiment: Stick chopsticks into water and find out why the chopsticks make a bend in the air and in the water.

(Air and water are two different media)

(3) Guidance for children in the optical area, actively try to use a variety of materials for experiments,

in the operation of the initial feeling and understanding of the refraction of light.

(4) Teacher evaluation of the activities, praise and encourage the exploration of the discovery of children

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

Intermediate Mathematics: Granny's Clothing Store

I. Activity Objectives: ⒈ in the context of helping granny look for buttons, according to the 2 characteristics of the identification of shapes, try to look at the marking diagrams pinned buttons, and feel the number of sequences.

⒉能够遵守操作规则，正确使用操作材料，清楚讲述操作过程与结果。

II. Activity Preparation:

Teaching materials: a picture of the grandmother, a number of markers, etc.

The children's operating materials: a piece of clothing without buttons, a number of red, yellow, blue, and green color features of the square (rectangular, triangular, and round) buttons, with 4-8 holes on them.

Three, the process of activities:

A picture of the introduction of activities to stimulate interest

- - Granny made a lot of clothes, want to open a clothing store, but she can not be completed alone, and would like to work with you to complete, willing?

Two help granny find buttons (classified by two characteristic markers)

⒈ consolidate the identification of shapes by 2 characteristics.

- First, let's find out what's missing from the top of the dress made by the grandmother. (Buttons)

--Really, there are no buttons on the clothes yet! There are so many different kinds of buttons that the old lady can't tell them apart, so would you like to help her?

-- (show the red and round symbols): However, the grandmother asks different things of each person, who can see what kind of buttons Grandma Bear wants Mr. Yang Yang to find? What shape of button in red? Is this one OK? Why?

--Summary: Yes! See these two signs is to find the red round button, two features require both find the right to put in.

🙂 First operation: look for the button according to the two features.

- later, please pick up your small basket to look carefully and gently say "the grandmother asked you to help find what kind of buttons?" Then gently say, "What color and shape of buttons did I find?" Finally, count how many buttons you found. (The grandmother is old, she can't stand the sound, we don't want to disturb her.)

-The teacher will go around and remind the children to tell the story while operating.

- children will be small pots good to put under the chair, and then began to focus on the exchange: you found a few what kind of buttons? How can you find them so that you don't make mistakes or miss them? (Look carefully at ......)

Individual attention: x x you find is not the red triangle button ah? Look carefully at the color, shape, are the same in order to put into their own small frame. Don't take away other people's buttons! (This is the button you are looking for?)

Three second operation: according to the amount of positive and negative sorting.

⒈ hand-mouth consistent counting.

- Huh! What's on your buttons? (dots)

--Oops! × × look really carefully, this dot is the button threading holes, take one out and count how many holes on it?

Are they all x? Count the other buttons!

Find the button with the most holes! Show me the one with the fewest?

🙂 Help granny pin the buttons (in positive and negative order).

- Grandma is so happy that you helped her find the buttons! Would you like to help her staple the buttons to her dress? Where to start? How do you staple a button? Grandma says that this question is a bit difficult, and only babies who listen and think clearly will know.

-- (show 4 to 8): Grandma told us here, who read it? x x looked so carefully, she must have read it! (Children free expression)

--Teacher summary: the top is 4, that means it is four buttonholes, the bottom is 8 that means 8 buttonholes, this arrow means slowly, slowly change, change more or less? Yes, it's slowly getting more ......

-- Take the basket to find a piece of your own clothing, read the grandmother's requirements for ordering buttons, and then pour out the buttons and put them on the table, and then you can order the buttons if you are clear about it!

The teacher will be on the lookout to see if the children can order the buttons according to the diagrams and the order of the buttons.

-- Show individual, centralized evaluation:

Who ordered the buttons on this dress? Here, Grandma's request is: the holes on the buttons are getting ......? It's really getting more and more, you're so smart, thank you oh!

This one? Who did it? Grandma's request is more and more ......? It turns out that the queue of buttons is lined up wrong, to change!

Four

- You are really capable, not only to help the grandmother find the buttons, but also made a new dress, the grandmother can be happy! She said: "Thank you for these smart, polite babies. Next time, you are welcome to go to his clothing store to sell clothes oh!" What should you say? (Teacher: Well, we're happy to help Granny!) After we're done, why don't we go out and relax? What should we say to the grandmother and the teachers?
