Advantages:

1. The review session is cleverly designed, following the students' cognitive rules and reasonably arranging the teaching steps.

2. Exercise questions should be linked to life, which is both interesting and practical.

3. Pay attention to mining knowledge points.

Disadvantages:

1. The excavation of teaching materials is not deep enough.

2. The courseware is very rough.

There are many forms of classroom design, but after each activity, there should be a summary and highlight the key points.

Extended material: draft evaluation of multiplication formula of 7.

Today, I listened to Mr. Chen's school-level open class, the topic of which is the multiplication formula of 7, the first volume of second-grade mathematics. In class, Mr. Chen leads students to explore the arrangement law of 7 multiplication formulas, enlightens students' wisdom and pays attention to cultivating students' thinking ability. The teaching effect is remarkable. Mainly embodies the following points:

1. At the beginning of the course, students' favorite cartoon characters in the Monkey King were used as learning materials, and three sevens and a multiplication formula of "372 1" were introduced, thus stimulating students' interest in learning and laying a good foundation for the other seven multiplication formulas below. Here, the teacher helps them well.

2. When students learn a multiplication formula of "372 1", open teaching is adopted, so that students can explore other multiplication formulas of 7 independently. Teachers patrol the classroom, select and monitor students' formula making in a timely and appropriate manner, feed back students' existing problems and solve them in time, which embodies the spirit of the new curriculum standard that students are the masters of learning and teachers are participants and organizers.

3. Teachers guide students to observe the arrangement rules of multiplication formula 7, and let students sum up the rules themselves, thus cultivating students' observation ability and generalization ability.

4. Teachers pay attention to the understanding of the meaning of the formula, so that every student can understand the meaning of the multiplication formula of 7, grasp the teaching focus, break through the teaching difficulties of this course, and achieve good teaching results.

5. Practice from shallow to deep, reflecting hierarchy. Finally, expand practice, train students' thinking ability, broaden students' thinking and make students' thinking develop in depth.

If we can further expand life examples and use the multiplication formula of 7 to solve some practical problems, it will help to cultivate students' awareness and ability to apply what they have learned, and the teaching effect will be better.
