First of all, by putting an umbrella, we can work out how many sticks a * * * has used. Let the students go through the process of 1 5, 2 5, 3 5, 4 5, 5 5, and get "15, 25, 35, 4 5, 5 5". A * * has used 25. Stimulate students' interest in learning through guidance and inspiration. When writing the multiplication formula of 5, I first explored and communicated with my classmates, and wrote the multiplication formula of "1 5,25" and "15 gets 5,2510", and then from help to release. The first two sentences are guided by the teacher, and the last three sentences are completed by the students. Understand the meaning of the formula, especially the last two sentences. Step by step, give students the process of exploring new knowledge, and let students explore and communicate independently to supplement other formulas of 5. This arrangement can not only reflect the students' dominant position, but also give them the initiative in learning. Teachers only inspire and guide students at key points, leaving students with sufficient time and space to actively participate in the whole process of knowledge. Cultivate students' inquiry consciousness and ability. Before students memorize formulas, students observe and compare, find the rules in the multiplication formula of 5, guide students to master and memorize the multiplication formula of 5, and cultivate students' ability of induction, generalization and analogy transfer.
Reciting formulas is a key point in this class, not only for students to recite, but also for the arrangement of exercises. We should use different questions to develop students' ideas, use different presentation methods to stimulate students' interest, and take care of students at all levels from the shallow to the deep. Therefore, knowledge should be included in the game when designing exercises. In this way, the effect of unconscious memorization is often more labor-saving than rote memorization.
There are still many shortcomings in the class. I will reflect on the shortcomings of this class myself.
1. When writing multiplication formula and compiling multiplication formula, I want students to distinguish formula from multiplication formula and deepen their understanding of the meaning of formula, so that they will not be confused in the future.
2. Remembering formulas is a key point of this lesson, but in the process of memorizing formulas, the method of memorizing formulas is not sufficient. If you forget a sentence, you should teach students how to remember it, so that students can remember the formula quickly and firmly.
3. Lack of timely evaluation, moderate encouragement can stimulate students' enthusiasm, so that they can get the joy of success.
