Analysis of children's situation: The main age characteristics of children aged 3-4 years old are that they are mainly inattentive and easily distracted. Children in this period are only curious about new things and activities that are vivid, concrete and vivid and can arouse strong emotions. Cognitive activities are basically carried out in the process of action. Through daily observation, it is found that the children in our class are very interested in counting. Half of the children can count the number within 5 with their hands and mouths, but they still can't understand that the last number is the total number of counted objects. Moreover, it is still difficult to count things.

Teaching content analysis: The syllabus requires that children aged 3-4 should be guided to count the objects within 3, and initially perceive the number of objects within 3. The perception of quantity is the most basic knowledge in mathematics, and it is also one of the first problems that children encounter when they begin to accumulate mathematical perception experience. Based on the analysis of children's situation and the Outline, the main content of this activity is to guide children to learn "less than 5 points". Vegetables are common things in children's lives, and children are familiar with them. Therefore, this activity takes the game plot of helping pigs pick vegetables happily as the main line, and integrates educational goals into it, which conforms to the humanistic characteristics of small-class children's games. Activities come from life, but also serve life and stimulate children's interest in learning mathematics.
