Find the decimal multiple of a number and check it. This lesson is finally over. Through the teaching of this class, I deeply feel that my knowledge is not solid enough and I need to strengthen myself.

In addition, the students' lack of awareness of cooperative learning in this class also caught me off guard, which I didn't expect. In addition, students spend too little time on writing, which is all caused by my own reasons, which eventually leads to the final thinking problem not being completed.

In the future lectures, I will try my best to speak every lesson well, so that students can understand and learn solidly.
