I. Contents of activities
This class is taught by children on the basis of learning addition and subtraction within 2345 and 6. Because children don't understand the concept of number, the textbook allows children to practice the decomposition and synthesis of 6 repeatedly through operation and observation, thus forming the consciousness of number concept.
This lesson belongs to the teaching of mathematical concepts, which is difficult for kindergarten children to understand. In order to help children master the key points and breakthrough points of teaching, according to the new curriculum standards of mathematics, this course strives to embody the following points in teaching methods:
1. Create vivid and concrete teaching situations so that children can learn mathematics knowledge in a pleasant situation. Make full use of the teaching resources provided by the teaching materials, combine with the environment of the activity room, show an activity chain to children with vivid and interesting storylines, stimulate their interest, mobilize their emotional input, activate their original knowledge and experience, and start thinking and consciously build knowledge on this basis.
2. Encourage children to think independently, explore independently, and cooperate and communicate. The current teaching needs to change children's traditional "receptive" learning style. Hands-on practice, independent exploration and cooperative communication have become important ways for children to learn mathematics. In teaching, let children think independently in specific operational activities, communicate with peers, experience the process of knowledge generation, and experience the fun of learning success.
3. Respect children's individual differences. Because children's life background and knowledge level are different, teachers should pay attention to individual counseling in the process of participating in teaching activities.
Second, the activity objectives
Kindergarten mathematics is a systematic and logical subject with its own characteristics and laws. The new syllabus puts forward that "mathematics education must let children feel the quantitative relationship of things from life and games, and experience the importance and interest of mathematics;" Teachers should guide children to be interested in the phenomena of number, quantity, shape, time and space in the surrounding environment, construct a preliminary concept of number, and learn to solve some simple problems in life and games with simple mathematical methods. " So I set the goal of this activity:
(1) Learn the decomposition and synthesis of 6, and try to summarize the relationship between the increasing and decreasing series on both sides. (ability goal)
(2) Stimulate children's interest in active exploration and communication with peers. (emotional goal)
Important and difficult
The germination of abstract logical thinking appears in large class thinking. When we know things, we can not only perceive the characteristics of things, but also make preliminary induction and reasoning. Therefore, the focus of this activity is to let children learn the decomposition and composition of 6, and the difficulty is to guide children to summarize the relationship between the two series on this basis.
Third, activity preparation
1, a group of 6 people, no one in each group has blank round cardboard.
Everyone has a watercolor pen.
3. One record for each group.
Fourth, the activity process
1, game import, review the composition of 5.
Displays the number 5 (the small disc just reviewed). The teacher held a board in his hand and showed, "I have 1 small dish?" You have four small disks. I have two. You record them in the form.
This design follows the principle that "games are children's main activities" and focuses on stimulating children's interest in participating in activities.
2. Study the decomposition of 6.
By throwing questions to help tadpoles find their mother's plot, mathematics is close to life and stimulates children's interest in exploration. As the outline points out: "Let children learn to solve some simple problems in life and games with simple mathematical methods." Large class children have the characteristics of autonomy, initiative and self-control. I arranged to operate the round card.
Movie activities, let children explore the four points of 5 independently in operation, and enlighten wisdom.
Because the children in large classes have enhanced their self-restraint, awareness of rules and persistence, when I ask for homework activities, I ask them to observe certain disciplines and cultivate their good study habits and behavior habits.
3. Guide children to summarize the relationship between the split series on both sides.
The germination of abstract logical thinking appears in large class thinking. When we know things, we can not only perceive the characteristics of things, but also make preliminary induction and reasoning. The children in this class are eager to learn, curious and like challenging learning content. Learning content should be difficult and challenging. I designed the connection between two series in the division formula of inductive 5.
4. Find and combine (the composition of learning 6).
Still follow the method of reviewing 5 before to summarize the composition of 6. And record it in the table.
The purpose of designing this link is to let children apply what they have learned to practice, guide children to be interested in the phenomena of number, quantity, shape, time and space in the surrounding environment, and ask them to record them and communicate with their peers, which is conducive to developing children's expression ability and cooperation ability.
5, the game out of the activity room "Little Tadpole Looking for Mom".
According to the decomposition and composition of learning 6 in the fourth link, introduce the story of "Little Tadpoles Looking for Mom", and play the game according to the children's own decomposed answers: 1 Only tadpoles swim in front and 5 tadpoles swim behind; Two tadpoles swim in front and four tadpoles swim behind. Let the children finish this lesson with great interest when reviewing the decomposition and composition of 6.
Fourthly, teaching effect prediction.
The introduction of games in this class can stimulate children's interest in learning and the classroom atmosphere will be very active. The key part of teaching adopts hands-on practice, and the children have a set of teaching AIDS, so everyone can use their hands and brains. High frequency and high density of practice are helpful for children to master the decomposition of 6 and ensure the classroom teaching effect. The teacher's simple guidance can be full of inspiring language, which will give children the motivation and enthusiasm to explore constantly; The process of clear hierarchy and moderate difficulty is also the process of consolidating and applying new knowledge.
