Correctly judging the number within 9 is the content of the next semester in the middle class. This activity requires children to consistently count the numbers within 9 and correctly say the total. Children are 4-5 years old and have a certain understanding of the concept of logarithm, so that the points caused by children's hands and mouths can lay a good foundation for children to learn mathematics conveniently in the future. Therefore, I set the content of this activity as follows.

1, cognitive goal

Through stories, observations and calculations, children can correctly judge the numbers within 9 and initially perceive the adjacent numbers.

2, thinking to expand the goal

Judge the number within 9 through activities and experience the fun of mathematics.

Important and difficult points: you can match numbers according to quantity.

Second, say to prepare.

For the fun, intuition and operability of this teaching activity, I prepared animal cards, bird cards, house cards, flowers, seeds, pencils and so on.

Third, talk about teaching methods.

This activity is aimed at middle-class children. The children in our class are young, active, playful, curious, active and easily distracted. According to these characteristics, I use pleasant teaching methods and use scenes and stories to run through the whole teaching process, so as to improve children's interest in learning, attract their attention and give full play to their learning enthusiasm.

Fourthly, talk about curriculum design.

Classroom teaching is the main way for children to acquire mathematical knowledge, form skills, develop intelligence and ability, and cultivate ideological and moral character. In order to achieve the expected teaching goal, I systematically planned the whole teaching process, followed a series of principles such as goal, integrity, inspiration and subjectivity, and designed four main teaching procedures.

1. Tell stories to arouse interest. In this session, I used the story "Spring Girl Comes" to attract children's attention, taking advantage of children's love of listening and watching.

2. Guide observation and judge quantity. In this link, I use cards to let children talk about the differences in the picture and cultivate their observation ability.

3. Use the turning point of the story to provoke contradictions and lead to adjacent figures.

4. Use operations to deepen children's understanding and judgment of quantity and match numbers with numbers. So as to further consolidate the content of this lesson and cultivate children's practical ability.

Through these four teaching links, this activity not only follows the laws of conceptual mathematics, but also conforms to the characteristics of children's cognition, guides children to observe, operate and acquire new knowledge, and pays attention to cultivating children's thinking and various abilities. In the teaching process, children are interested in learning and gain something through the learning methods of moving their mouths, hands, eyes and brains.

In this activity, I integrated the fields of language, common sense, calculation and so on, which was a complete mathematical activity.
