Teacher: Teacher Qu.

Design intent:

Because I just learned the composition of 2 and 3, the first two times were mainly divided by the teacher to help the children understand the meaning of division and combination, and then let the children express the process of division and combination in language and initially understand the relationship between the whole and the part. Then, under such conditions, I designed such an activity, so that children can learn the division of 4 through their own attempts and explorations, return time and space to children, and let them acquire knowledge and find answers through their own explorations.

Activity objectives:

1, the division of inductive learning in game activities.

2. Cultivate children's hands-on ability, observation, logical thinking and reasoning ability.

3. Constantly explore various divisor methods in operation activities to stimulate children's thirst for knowledge.

Activity preparation:

Teacher: 4 big fish, 3 fish tanks, 12 small fish.

Children: Each child has four pictures of small fish, a record sheet and operation questions.

Highlights and difficulties of the activity:

Let children learn various points of 4 in the exploration operation.

Activity flow:

1, the game: "We are all good friends". Review the division of 3.

Today, let's play the game "We are all good friends". Ask three children to read nursery rhymes together:123,321. We are all good friends. Three good friends, hand in hand, you squat down and I stand up. How many can three be divided into? 3 can be divided into 1 and 2...2. Children's operation: "dividing small fish", constantly exploring various methods of dividing 4 in operation activities, and learning to record.

Teacher: xu teacher got a call from the mother cat. She asked the children in the class to help the kitten divide the small fish into two small fish tanks. How to divide it? Teacher: How many small fish are the four small fish divided into? Children: Four small fish are divided into 1 small fish and three small fish.

Teacher: So how many can four be divided into?

Child: 4 can be divided into 1 and 3. Please repeat it in class, and the teacher will help you write it down on the blackboard. ) Teacher: Mother Cat, please think about it. There are several ways to divide four small fish into two parts. Please take out four small fish from the basket on the table and write them down on the record sheet to see who can separate them quickly and accurately.

3, children's operation, teacher guidance. (Let a child do exercises on the stage alone)

Teacher: Please tell us how you divide them. How many are the four small fish divided into? How many can 4 be divided into?

Young children: 4 fish scores 1 and 3,4 scores 1 and 3; Four small fish are divided into twos, and four can be divided into twos; Four small fish are divided into three and 1, and four can be divided into three and 1.

Teacher: Great. Are there any differences among other children?

Child: 4 can be divided into 1 and 3, 4 can be divided into 3 and 1, and 4 can be divided into 2 and 2. Teacher: Do you think these two methods are easy to remember, children?

Young children: easy to remember.

Teacher: They all have nice names. The first is called sequential method, and the second is called reverse method. Mother cat is very happy that the children in our class help her divide the small fish. She thinks the children in our class are very clever.

4. Consolidate the game: practice in groups.

Mother cat said: Autumn is here, and the fruit is ripe. Please ask the children to help her divide the fruit. Please listen carefully to the requirements: 1, 2, 3 groups of children fill in the blanks according to the pictures, and indicate the scores with numbers; Children in groups 4, 5 and 6 divide the fruit into two plates and indicate them with circles. Count the children in groups 7, 8 and 9. Count the pictures according to their contents, and show them in figures.

Ask each child to work out a problem together. Be careful not to point the pencil at other children or poke yourself or your friends. Please check it carefully when you are finished.

When you are finished, please show each child the results of the exercise.

Today, we learned the composition of "4". Mother cat is glad that the children in our class have helped her a lot. She invited the children in our class to play games outdoors. Let's go together.
