Changes of Mathematics Graphics in Kindergarten Class 1 Activity Objectives of Teaching Plan

1, can correctly identify triangles, squares and circles, and can name the graphics.

2. Experience the fun of the game on the basis of understanding the graphics.

3. Be able to name cuboids and cubes and know their main features.

4. Further consolidate the understanding of square and rectangle, and understand the difference between plane and solid.

Activities to be prepared

1. Paths with triangular, square and round "pits" and triangular, square and round "stones".

2, the home of three graphic babies.

3. The kitten has one hand hanging in the air, and a figure is attached to the back.

Activity process? Collective understanding of triangles, circles and squares.

Teacher: "Mother Cat invited some graphic babies today. Let's meet them. "

Second, children "build roads" to consolidate their understanding of graphics. 1, teacher: "Babies are really capable. Now Graphic Baby invites us to their home.

The children are leaving. Stay with their good mother, or you will get lost. "Play music and walk like a kitten.

2. Come to the side of the road. Teacher: "Oh, what's the matter," said the child. "There are many pits on the road."

The teacher said, "What shape is the pit?" The children answered. Teacher: "What can we do to fill the road?" The child replied.

Teacher: "Look, babies, there are so many stones on the roadside. Let's use these stones to build roads. " When the child builds a road, he reminds: "The baby should use his brain, and what kind of stone is just right in the pit."

3. The teacher checks whether the path has been repaired. Teacher: "What shape stones do you use to build roads? (Please answer individual children), the path has been repaired. Let's talk about what figure you are standing on when we walk. " (Teachers demonstrate first, children demonstrate later)

4。 Show the cuboids and cubes and tell the children their names.

Give the children (each group) a cuboid, a cube, a square and a rectangle, and let them play with it at will.

Touch them, have a look and compare their similarities and differences.

6. Comparison and summary between teachers and children: Counting in order, a cuboid has six faces, and each face is generally rectangular.

A cube also has six faces, and each face is a square (compare each face of a square and a cube). Its six faces are the same size.

7. Let the children tell which objects they have seen in their lives are cuboids. Which objects are cubes?

Third, come to the home of graphic baby.

1, teacher: "Look, this is the home of graphic babies. Can you guess which graphic baby's home this is? " Guide the child to speak.

2. Be a guest according to the figure on the child.

Teacher: "My baby cat is really capable. Now I will invite the baby cat wearing a triangle to visit the house of the triangular figure doll.

Say hello at the same time. Come back and say goodbye to the triangle doll. "

Teacher: "This time, let's go to be a guest together, according to your figure. The method is the same as above "

3. Whether the teacher's verification is correct.

Fourth, end the activity.

Teacher: "Baby Cat, are you tired after playing for so long?" Let's go home.

The activity goal of the second lecture on the change of mathematical graphics in kindergarten middle class;

Length perceives the change of graphics during the process of graphics folding and deformation.

2. Interested in combining and analyzing graphics.

3. Cultivate spatial awareness and the ability to use your hands and brains.

Key points: Children change shapes such as squares, rectangles, triangles and circles by folding and spelling.

Difficulties: Guide children to discover that graphics can change and transform with each other, and can produce different numbers of various graphics.

Activity preparation:

All kinds of geometric graphics cards, some of which are geometric graphics operated by children.

Activity flow:

Show all kinds of geometric figures first to guide children to observe.

Children, do you know these graphic babies? What graphic treasures are there? Graphic baby has a wish. They all want to transform like transformers. Today, teachers and children come together to help the graphic baby change.

Second, the hands-on operation of folding graphics.

1. Teacher: Show me a square. Let the children see how the teacher helps Fang Bao transform. Tell me how to fold this figure in half. Question: Fang Bao has changed. What will it become? ? Young: rectangular.

You see, what will happen if the teacher changes it again?

Yang: Triangle, a big rectangle and a small rectangle.

Teacher: Little friend, how did the teacher change just now? ? Inspire children to say a discount.

By the way, as long as you gently fold the graphics baby, the graphics will change. Kid, will you change? Please exchange the square paper on the table with the teacher.

Teacher: How will you change? See what it can become.

Children can change their graphics by hand.

2. Teacher: Rectangular babies will also change. Can we help it together?

Take out the rectangle and guide the children to bend the figure.

Ask some children to demonstrate the front folding and praise the folded children.

Teacher: Guide children to say what rectangular babies can become.

The child learns what the rectangular baby has become while operating.

3. The teacher guides the children to bend triangles, rectangles and circles, and see which group of children becomes more and faster in groups.

Children are divided into triangle, circle, trapezoid and triangle to bend.

4. The teacher concluded that the children are really capable of helping the graphic baby realize the wish of becoming square-triangle and rectangle; Round-semi-circular, fan-shaped; Rectangular-into a triangle, and a square; Triangle-divided into small triangles and squares; Children can also do it by hand. It is a gorgeous transformation of graphic baby. Would you please think about it? If you fight hard, the graphics will change and become more magical. Do you want to be a magician?

Third, use graphics to spell objects. Let's play puzzles together! Look at these figures. The baby can put them together.

The teacher instructed the children to spell these numbers by hand.

Teacher: Do any children want to come up and show me the puzzle? Teacher: We can also spell many numbers. Please use your brains to see who can spell well and spell more things. Let's compare it.

Fourth, teachers use multimedia to show children's puzzles.

Teacher's summary: Today, all the children use their brains to turn our graphic baby into another graphic baby. You're amazing!

The expansion of verb (verb's abbreviation);

Children, are these little figures fun? (fun! Then we put these figures in the puzzle area and put them on white paper. It will also become a nice sticker. Give these pictures to your closest relatives!
