The activity goal of 1, the excellent teaching plan of large class mathematics, the second classification of numbers;
1. Learn to make secondary classification according to two (three) different features of graphics.
2. Cultivate children's analytical and inductive abilities and operational interests.
Activity preparation:
The first operation: several circular and square pictures of two colors; The second operation: two colors, one triangle and square picture with different sizes for every two children. Classification map.
Highlights and difficulties of the activity:
Focus of activities: The graphics can be classified twice according to their different characteristics.
Activity difficulty: guide children to cooperate and record.
Activity flow:
First, the beginning part: the game to stimulate children's interest in activities.
1, the teacher showed us around the home of the graphic baby.
2. Let the children talk about the babies in the graphic baby family.
Second, the first operation: each family carries out the second classification.
1, please choose a graphic baby to play with this graphic baby.
2. Ask the graphic babies to think about how to divide them.
3. Ask children to classify according to a feature of the figure. And let the children talk about how they are classified according to what characteristics, and the teacher will record it.
4. Observe the separated figures to see if they are all the same now. See what the difference is. How can we split up?
5, the children are classified twice, and the teacher takes notes.
Third, the second operation: group operation to expand children's thinking.
1, the teacher said the operation requirements: two children discuss in groups, one child classifies according to the discussion results, the other child classifies records, and then classifies records in the same way according to other characteristics.
2. Ask the children to cooperate in pairs. Individual guidance of teachers.
3. Conduct a collective inspection of the children's operation results.
Fourth, activity extension: classify all kinds of small animals twice.
1, all kinds of small animals are classified once. (land, sea and air)
2. The second classification: the sea is divided into fish and amphibians, the land is divided into birds and wild species, and the air is divided into birds and insects.
To arouse children's interest in activities, we must first contact the content of the activities.
Let children play with graphic babies and experience the fun of graphic classification.
Let the children make a secondary classification according to the different characteristics of graphics.
The teacher followed up with words while recording, laying the foundation for the children's next group activities.
Explain the operation requirements clearly so that children can operate in groups better.
Expand children's thinking.
Activity reflection:
In mathematics teaching, it must be emphasized that children should operate materials by themselves, explore and learn in practical operation, and gain perceptual experience about mathematical concepts. Only in the process of "doing" and interacting with materials can children experience a certain mathematical concept attribute or law and gain direct experience. I use a story of "separating the graphic baby" throughout, and the child is easy to understand and willing to invest in it. In addition, I provide children with sufficient operation materials and step-by-step guidance, so that children can truly discover and summarize the characteristics of "graphic secondary classification" in the operation process and let them complete the task with passion.
Excellent teaching plan of large class "Two-level Classification of Graphics" 2 Activity objectives:
1. Learn to make secondary classification according to two (three) different features of graphics.
2. Cultivate children's analytical and inductive abilities and operational interests.
3. Willing to explore, communicate and share.
4. Promote the coordinated development of children's innovative thinking and movements.
Activity preparation:
The first operation: use a number of circular and square pictures in two colors; The second operation: every two children have a classification map, with two colors, triangles and squares of different sizes.
Highlights and difficulties of the activity:
Focus of activities: The graphics can be classified twice according to their different characteristics.
Activity difficulty: guide children to cooperate and record.

4. Observe the separated figures to see if they are all the same now. See what the difference is. How can we split up?
5. The children are divided into two times, and the teacher takes notes.
Third, the second operation: group operation to expand children's thinking.
1, the teacher said the operation requirements: two children discuss in groups, one child classifies according to the discussion results, the other child classifies records, and then classifies records in the same way according to other characteristics.
2. Let the children work in pairs, and the teacher will guide them individually.
3. Conduct a collective inspection of the children's operation results.
