Guided by principled and methodological teaching comments, open classes can provide a solid step for teachers' professional growth. The following is my teaching plan for the open class of large class mathematics, welcome to refer to it!
The changeable teaching plan of graphic open class cultivates the innovative spirit and quality of children's bold imagination and exploration through their own attempts and experiences. Encourage children to practice boldly and dare to try new methods.
[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.
[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.
[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 music? Looking for friends? Admission.
2. Teaching: games? 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 put this? Round? Stick it on the blackboard and discuss: What else to see? 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 a table. (rectangle, square, ellipse, triangle)
3. Teacher: Shall we have another game? Super magician? Games.
Pick up a circle and change it. Face change? What have you become? 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.
"Puzzle" Math Teaching Plan Background: In a math activity of looking at pictures and puzzles, I provided children with patterns for them to do puzzles as usual. Because it is an operational activity, children are very interested in it and can spell it as required. After spelling, I asked the children to tell me how to spell, using a few pictures and texts, and then recording them. At this moment, a child named Wang Zhipeng in the class asked? Teacher, the villain I spelled is not the same as the picture, okay? It turned out that the feet of the villain he spelled were rectangular, while the characters spelled triangles. At that time, I thought: Yes, why do you have to use triangles? So I had the following activities.
Activity preparation: all kinds of pictures and texts, recording paper and pens.
Activity process
1, looking for graphics (putting all kinds of graphics with different colors, shapes and sizes together)
(1) One group takes a red square, two groups take a green rectangle, three groups take a yellow triangle, four groups take a blue circle, five groups take a red trapezoid and six groups take a green semicircle. Let's see which group is correct and fast.
(2) Please take out five red circles, six yellow squares, eight green trapezoid, seven blue triangles and four red semicircles in each group. When one child in each group takes it as required, other children should help him count it after he finishes, and see if he counts it correctly. The children are very motivated and quick, and there is another group that has been at the end, but all the members in the group are helping, helping to find and count pictures. This arrangement mainly takes into account that there are new children in this class this semester. Some children will find the same figure according to the figure, but if the teacher asks him to bring a figure, it may take a long time to find it, especially the rectangle and square will be mixed together, and the trapezoid can't be found quickly. Through these two operation activities, one is to help children review graphics, and the other is to help children review and count objects correctly. )
2. Spell, speak and record. The teacher provides pictures and movies for the children. The teacher said something for the children to spell. When you're done, tell me how to spell it. How much do you use for each pattern? Write it down.
(1) Let the children spell a villain. When I was on patrol, a child named Wang Zhipeng said to me, Teacher, I spelled a woman. ? I just looked around and said? Not bad? But I thought: Why a woman? Then I went to see other children fight. At this time, inspired by the children in Wang Zhipeng, I paid attention to the spelling of other children and found that the little people spelled by children were all different. Only a few children in the class spell the same as others, but everyone else is different. After spelling, I will ask Wang Zhipeng to tell me how he spelled it. Wang Zhipeng said? I put the girl's head into a circle, her body into a square, her hands into a rectangle and her skirt into a trapezoid? Jason said: I also spelled a girl. It was a circle that spelled her head, a triangle that spelled her hand and body, and a trapezoid that spelled her skirt, and her legs were blocked by the skirt. ? There are also many girls who can spell, but not in skirts, but in their heads. For example, Zhao Lei uses two semicircles to spell the girl's braid, and Guan Ye uses two circles to spell the braid (just spell a villain, children spell different girls with different graphics, and each child can express his spelling process in his own language. If the child doesn't tell you, you may not understand it at first sight, but after the child's explanation, it was really an epiphany. As Reggio said, children have one hundred languages, one hundred hands, one hundred thoughts and one hundred ways of thinking, playing and speaking. )
(2) spelling a house Some children spell a triangular roof, some spell a trapezoidal roof, some spell a rectangle with a roof and windows, and some have two windows; There are all kinds of single-door and double-door houses in front. At this time, I'm not telling my children what graphics to use to spell the house, but what to spell with them. Because of this, there will be such a result. Children seem to be architects. They have built all kinds of beautiful houses, and their imagination and creativity have been fully exerted. ) expand the activity group to work together to spell one? Our kindergarten? After spelling, each group can communicate.
