Lesson plan of Graphic Puzzle 1 1. Activity objectives
1. Understand ellipse and semicircle by comparison.
2. You can learn more about ellipses and semicircles through human modeling.
Second, the activity preparation
1. A circle, a semicircle and an ellipse velveteen teaching aid, PPT courseware.
2. Each person has a piece of circular, semi-circular and oval paper with the same diameter and puts it in each group's small basket.
3. Children's activity materials "digital graphics" and watercolor pens.
4. Give everyone three shapes of hard paper.
Third, the activity process
Activity import;
1. Know the ellipse.
-Show round and oval velveteen teaching AIDS to help children find the round.
-children find the circle and ellipse in the basket on the table and compare them, and talk about the difference between the two shapes. -Inspire children to exchange experiences and talk about their findings.
-Inspire children to observe and compare two figures by folding them up, down, left and right, and know that the two creases on the circle are equal in length and the two creases on the ellipse are unequal in length.
-Guide children to "shape" ellipses with their bodies. For example, squatting on the ground, pulling the upper body as far as possible horizontally to make the body look like an oval.
-inspire children to think of as many ways as possible and find people to cooperate when necessary.
2. Know the semicircle.
-Show semi-circular velveteen teaching AIDS. What shape is it?
-Children find a semicircle in the basket and compare it with a circle.
-inspire children to exchange and compare their findings and know that a semicircle is only half a circle.
-Guide children to "shape" a semicircle with their bodies.
For example, squat, arch your arms above your head, and inspire children to think about other expressions.
3. Color the graphics.
-Find out the ellipses, semicircles and circles on the pictures of children's activity materials, and draw them in three different colors to distinguish them.
suggestion
1. With the help of physical exercise, children can deepen their understanding of shapes and enrich their experience of space and shapes.
2. Provide various graphics in the math corner for children to spell.
3. Guide children to find objects similar to circles, ellipses and semicircles in their daily lives.
"Graphic Puzzle" Middle Class Teaching Plan 2 Activity Target:
1. Understand the simple relationship of graphic combination and develop the ability of observation and discrimination.
2, can use a variety of graphics to spell painting, and can carry out simple painting.
3. Experience the fun of collage and the joy of success.
4. Enhance the interest and ability to participate in environmental layout and experience the happiness of success.
5. Cultivate children's practical ability and communicate boldly among peers according to observed phenomena.
Activity preparation: several triangles, rectangles, squares, circles and semicircles of different sizes, crayons, paper, paste and rags.
Activity flow:
I. Import: graphic robots
1 Children, Teacher Gu brought you a new friend today. Let's see who it is.
2. Then do you know what graphics it is made of? Please raise your hand after careful observation. (triangle, circle, rectangle, square, semicircle)
Do you know which side of the robot body the triangle is on? How many triangles does a * * * have?
What about circles, semicircles, rectangles and squares? Where are they on the robot body? How many are there in each?
4. The children speak well. Robots are composed of triangles, circles, rectangles, squares and semicircles.
Second, new funding.
1, ask individual children to try, and the teacher will give guidance and help.
(1) Various shapes can form a robot, so what can these shapes spell? Ask your friends to think about it first and then talk about it.
(2) The children speak really well! Do you want to try it yourself? (Think) Then Teacher Gu will invite every child to do a collage in the future.
2. The teacher explains the operation requirements
Before doing it, Mr. Gu has several requirements, which I hope the children can do.
Let the children choose the graphics they need in an orderly way. First, put them together on white paper, and then stick them on the paper with glue.
After the graphics are put together, we can draw some decorative patterns with crayons to make the picture more beautiful.
3, children's collective homework, teachers tour guidance.
Third, the exhibition of works
Today, our children played their own whimsy, some spelled things, some spelled things, and spelled out beautiful works. You can put it in your homework bag after class and let your good friends, parents, uncles and aunts look at it together, ok?
Activity reflection:
Children's interest points are the starting point of children's active learning, and education triggered by children's interest points can become the internal motivation of children's active learning. Autumn leaves come from children's lives and are loved by children. Spelling, pasting and painting are activities that middle-class children like, so leaf collage is organized according to children's interests and internal needs. The outline emphasizes "children's autonomy and creativity should be emphasized in activities", and many leaves are provided for children to choose freely according to their own interests and needs, creating a relaxed and free learning atmosphere for them, which fully embodies the characteristics of openness. At the same time, I can carefully observe and listen to the children's words and deeds, grasp their interests in time, and naturally trigger their experience of being close to the children themselves, and encourage them to express themselves in their favorite way. While satisfying children's mouth and mouth, we can pay more attention to let thinking participate. For example, I put the leaves together to make it look like a chicken and asked, what do you think it looks like? Then show other shapes of leaves, "What else can I do?" This method of "playing tricks" on children's thinking can not only mobilize children's existing experience to participate in learning, but also effectively promote the development of children's divergent thinking ability and effectively pave the way for subsequent creative activities. In the activity of wagging the tail, children's subjectivity can be truly reflected and their intelligence can be improved. In the exploration activities, children happily and independently gain learning experience, which makes their original spirit and practical ability be exercised. There are also shortcomings in the activities, such as how to make every child experience the joy of success, gain the strength of enterprising and share the harmony of cooperation.
"Graphic Puzzle" Middle Class Teaching Plan 3 Activity Target:
1. Review five kinds of figures: square, rectangle, triangle, circle and trapezoid, and remember their characteristics deeply.
2, through the "train" game, learn to help the graphic baby go home to classify. Can make careful observation.
By looking at the scenery and food, we know that graphic babies can change many things in our lives. We can say that these things are changed by those graphic babies.
4. Cultivate children's dynamic ability, give them a number of different or identical graphic babies, and let them use their imagination to conjure up some items in their lives.
Activity preparation:
1, a "rag doll mother and son".
Tie them to chairs.
) 2. A "patterned carpet".
All the graphics are cut out, leaving the graphics blank.
) Then distribute the cut graphics to the children and let them make up.
3. One train ticket for each person.
(Including trapezoid, square, rectangle, circle and triangle.
4. A small train when making boxes, (5 carriages, triangle, circle, trapezoid, rectangle and square respectively.
5. Post a photo of the house, big trees, candied haws and candy displays.
6, each a piece of white paper, each a number of graphic dolls, double-sided tape.
Activity flow:
Introduction of the story: What do you see, children? The doll was tied to a chair. )]
1, the teacher told a story: a big, bad wolf caught the little monkey and the mother monkey and then tied them to a chair pitifully.
Do you want them out? The wolf said there was only one way to save them.
The damn wolf tore down the tiles.
Only when you spell it correctly can you let the monkey go. These drawing teachers pick them up and give them to you. Whether they can be saved depends on the babies. Mr. Wu also has some graphic tiles in his hand. Let Mr. Wu spell them first.
2. The teacher demonstrates. Children operate together.
Second, babies are really smart and kind. They all put the carpets together and saved the monkey. They were very grateful to us and gave each of us a new train ticket, so that we could eat while watching the scenery.
1. Show me the train tickets (square, rectangle, trapezoid, circle, triangle). And children, their names, introduced the characteristics of these graphics.
2. Distribute train tickets with the class teacher. One for each person.
(triangle, square, rectangle, circle, trapezoid.
) 3. Let the children put the train tickets in the corresponding carriages, let the class teacher be the scrutineer, and the wrong children will vote again. If you vote correctly, you can sit in the "scenic spot"
3. Enter the scenic spot, observe the scenery (house, big tree) from the children, and ask which graphic babies made the house and big tree respectively.
See what else is in the photo.
Monkeys prepare two kinds of food (candied haws and sweets) for children.
) and ask which two kinds of graphics are used to make these two kinds of food.
Fourth, graphic babies can conjure up many useful things in our lives. Now, please use your imagination to create something with the figure on the table, which is not necessarily the same as the teacher's.
Five, children operate, teachers patrol, praise and encouragement.
Sixth, show children's works.
