Teaching objectives

1. Knowledge objective:

1. Let students perceive numbers within 100 through specific scenes, and further perceive numbers within 100. They will use "more, less, more and less" to describe the relationship between numbers.

2. Ability goal: to cultivate students' observation ability and generalization ability.

3. Moral education goal: let students feel that mathematics is everywhere.

4. Emotional goal: to activate students' understanding of "more, less, more and less"

The subjective demand of "more" makes students love and enjoy learning, experience success in activities, and cultivate students' spirit of unity and cooperation.

The above goals are infiltrated into mathematics activities, forming a combination of moral education, intellectual education, knowledge and ability. The key and difficult point of this lesson is to understand the meaning of "more, less, more and less" and use it to describe the relationship between numbers. Guide students to make correct estimates and cultivate their ability of observation, analysis and comparison. Cultivate students' sense of number and mathematics application.

Teaching focus

Ask the students to describe the relationship between the two numbers by specifying the numbers within context awareness 100 and using "many", "few", "many" and "few".
