We have been studying numbers within 100 all this time. Counting, reading and writing are all laying the foundation for the lesson "Who has more red fruits". This lesson is mainly to further understand the meaning of numbers, compare the size of numbers within 100, and cultivate a sense of numbers. Therefore, in the learning process of this class, I grasp the above objectives, and hope that students can master the method of comparing numbers within 100 in a pleasant teaching environment, and can correctly compare numbers within 100. By studying, I can stimulate students' interest in learning, cultivate my comprehensive abilities of observation, comparison, thinking and language expression, and lay the foundation for studying the comparison of multiple digits in the future.

In the first volume of Senior One, we have compared the sizes of numbers within 20, which can be expressed by symbols, but we only have a preliminary understanding of the numbers within 100, and it is still difficult to compare the sizes of numbers abstractly. So I want to create concrete, vivid and interesting situations according to the age characteristics of students and their familiar life experiences, so that students can perceive the size of two numbers, and then gradually transition to the comparison with the help of counters, and finally compare the sizes of numbers abstractly. Students are good at summing up and come up with several different methods. For example, through the intuitive comparison of two strings of red fruits held by a little monkey and a little bear, we can know who is older and who is younger. There is also to determine the size of the number by comparing the numbers on the tenth digit; Compare the sizes of numbers in the order of counting. Through the comparison of 100 and 99, it is concluded that the number with more digits is large and the number with less digits is small.

I turned the new class into an activity class, which greatly stimulated the children's interest in learning, but the self-control ability of the first-grade children is still very weak, and I am a little overwhelmed by the grasp of the classroom rhythm. The whole class seems lively, but some students are still confused about the learning content. I still need to work hard to grasp the classroom. I don't want to sum up more experience in my future work to improve myself.
