Find out how many times one number is another. The evaluation is as follows:

1. Both teachers pay great attention to encouraging students in time in a class whose number is several times that of the other, so that students are full of confidence in their studies, with neat blackboard writing and fluent language. It can be seen that the two teachers have made great efforts in teaching at ordinary times and are worth learning.

2. After listening to teacher XXX's lecture on how many times one number is another, we can closely focus on students' lives, highlight the hierarchy, diversity, openness and interest of the content, and provide students with room for thinking expansion. These exercises designed by teacher XXX range from observation and operation to filling in the blanks and calculation, from concrete intuition to abstract thinking.

The gradual improvement of teaching requirements reflects the clear intention of letting students deepen their understanding and master methods in different forms of activities. Moreover, finishing homework in class can cultivate students' good homework habits, ensure the correct rate of homework and reduce the burden on students.

3. After listening to teacher XXX's class (solving problems), this class is rigorous in structure, easy for teachers, pleasant for scholars, solid and effective, which fully embodies the elegant demeanor of teacher XXX, a famous teacher. After listening to this lesson, I gained a lot.

4. Teacher 4.XXX can accurately grasp the starting point of students' learning in a class whose number is several times that of another. Although the concept of multiplying learning efficiency is abstract, most students have obtained performance cognition through previous multiplication and related knowledge learning, combined with the cognition of life practice.

Teachers use textbooks creatively. From the beginning, teachers pay attention to cultivating students' divergent thinking, ask open questions, let students speak for themselves, and cultivate students' self-thinking without designing circles.

In this class, teachers should pay attention to the idea of combining numbers with shapes while teaching. The perception and understanding of the concept of "time" starts with graphics, which makes the extracted concept intuitive, visualized and simplified, from putting pictures to looking at pictures to getting rid of intuition.

The process and practice of describing the multiple relationship with numbers embodies the infiltration of the idea of combining numbers with shapes, which makes students influenced by mathematical ideas imperceptibly.

Class evaluation:

As the name implies, it is to evaluate classroom teaching. It is an extension of post-lecture teaching. It is an activity to comment on the gains and losses of teachers' classroom teaching, and it is an important means to strengthen teaching routine management, carry out educational research activities, deepen classroom teaching reform, promote students' development and improve teachers' professional level.

Classroom evaluation is a regular activity in the process of teaching and scientific research.
