Distinguishing between odd numbers and even numbers within 10 is the basic requirement for children in the early stage of large classes. The traditional teaching method is to adopt the collective teaching method, so that children can count two and two numbers. The number just counted is a double number, and the remaining numbers are abstract words such as singular numbers for children to remember and distinguish.

It is clearly pointed out in the outline that the goal of mathematics education is to "feel the quantitative relationship of things from life and games and experience the importance and interest of mathematics." The new goal and educational value of mathematics education embodied in the syllabus require our teachers to change their educational concepts, and gradually form children's perception and consciousness of mathematics in the real scenes of life and games and in the process of solving problems, so I adopted a variety of games to carry out this activity.

How to integrate boring math activities into children's lives and stimulate children's interest in math activities is the main goal of math activities. Froebel, the father of preschool education in the world, first put forward the idea of children playing games. Educator Mr. Chen Heqin once said: Games are the life of children. I designed this teaching activity, which abandoned the old teaching mode in the past, and made games run through the whole activity, so that children could distinguish odd numbers and even numbers within 10 in happy games. In the activity, I created a situation of "drawing big and small prizes". Let children perceive and understand the concept of odd and even numbers in the "lucky draw" full of life, and distinguish odd and even numbers within 10 in operation. On this basis, it is further expanded to inspire children to find out which objects are singular and which things are even in the body or surrounding environment, and to promote children to have a more thorough understanding of single, even and related concepts in a series of step-by-step and challenging games. The children learned the odd and even numbers within 10 in a relaxed and happy atmosphere.

In the activity, I used the usual method of children queuing, let two groups of children line up in front to see where they become children, then this number is singular; Next, I let the children play with snowflakes. First, I put two snowflakes in a line to see if the number of snowflakes is odd or even. The children can tell me the answer very well. Finally, I let the children play snowflake games with other children. The children learned the odd and even numbers within 10 in a relaxed and happy atmosphere.

In short, the effect of this class is basically very good, the children have mastered it well, and the basic difficulties have been broken through, achieving the effect I want.

I hope I can help you, and I hope I can adopt it satisfactorily.
