Teaching plan of "learning the second classification" in large class mathematics activities 1 learning the second classification
Activity objectives:
1, learn to classify things twice according to two different characteristics, and experience class contains relationships.
2. Cultivate children's analytical and inductive abilities and operational interests.
Activity preparation:
Teaching AIDS: several triangular and square pictures of different colors and sizes; Some pictures of fruits and vegetables;
Activity flow:
First, the beginning part:
Organize children to listen to music, sit still and stimulate their interest.
Second, the basic part:
1, observation and demonstration. Show the graphic cards and let the children observe their characteristics. Think about how to divide these figures into two groups. How many different ways are there? The children have a discussion.
2. After the children discuss and answer, the teacher chooses a division method to demonstrate, such as dividing the graph into two parts with different shapes. On this basis, inspire children to think about how to divide each part into two parts. The teacher demonstrated division.
3. Teacher's summary: Graphics can be divided into shapes first and then into sizes; Can also be divided according to the size first, and then according to the shape; You can also divide them by color first, and then by shape.
4, children's operation. Let the children observe the shape characteristics of the graphics, and then classify them twice according to the characteristics.
5. Review and consolidate. Teachers guide children to complete the exercises in children's books, and further consolidate their analytical and inductive abilities.
Third, the last part:
The teacher evaluates and summarizes and leads the children to outdoor activities.

Activity reflection:
In this teaching activity, the children's understanding of the two categories gave me unexpected surprises, and also left me with questions worthy of further consideration: how to deal with "motion" and "static" in teaching activities flexibly and organically in games; How to make children's thinking more open and active, stimulate children's internal activity mechanism and produce positive experiences? I keep trying and changing all kinds of activities to make children like math class more through relaxing and happy activities.
Encyclopedia: classification refers to classification according to category, grade or nature.
