The teaching of this course is carried out in the order of counting, reading, writing and counting. Students learned the number comparison within 20 last semester, and learned the number within 100 this semester. On this basis, it should be easy to master by comparing the numbers within 100.

Teachers have consolidated this knowledge before the new lesson, paving the way for continuing to learn the following new lesson. On the other hand, in daily life, they also have the opportunity to personally contact or even solve similar problems.

In the whole teaching activity, Mr. Liu always puts himself in the position of organizer and guide to create a positive learning atmosphere for students.

As follows:

Junior high school students seldom participate in teaching activities because of their cognitive needs, but only because they are interested in the teaching activities themselves. The problem is the core of mathematics, and mathematics generally starts with the problem. Creating effective problem situations can stimulate students' interest in learning and mobilize their active participation.

In order to further help students find out how to compare numbers within 100, Teacher Liu uses a counter to help students find out how to compare numbers. Ten digits are the same. If you look at one digit, two digits are bigger. If there is no egg chart and no counter, how can we compare two digits?

The exercises designed by the teacher, from the comparison of ten identical numbers, to the comparison of ten different numbers, and then to the comparison of two digits and three digits, reflect the hierarchy and gradient in the design of teaching process. Finally, guide the students to draw ten different conclusions and look at ten directly. If there are more than ten, there will be more than two digits. This method shows children's cognitive characteristics from concrete to abstract.

The biggest feature of first-year students is that they love to move. Let students learn mathematics in activities, which is a learning method advocated in the Standard. This lesson is embodied in the math game "Vote for Letters", which can provide students with opportunities to engage in math activities and exchanges. Students can learn and practice in activities, so that students can develop in activities.
