In the ordinary chat process, we often hear many people lament that China people always put emphasis on the beginning and neglect the end in everything they do. Like many film and television works, the beginning is very attractive, but it is boring to see the end. And our classrooms are often the same. Many teachers attach great importance to the introduction of new lessons, but the ending is not satisfactory, which often gives people a feeling of anticlimactic. The beginning of a class is important, but what should we do? In the exploration of teaching practice, the author thinks that the effect will be better from the following aspects.

First, summarize the preview style.

This ending is the most common and commonly used. In order to let children master the knowledge of this lesson systematically, we often guide them to summarize and summarize what they have learned in their own language. This can exercise children's learning ability, let children have a systematic and complete impression of what they have learned, and lay a good foundation for the next lesson.

For example, after learning parallelogram, I asked my children to try to sum up: (1) What kind of figure is parallelogram? (2) What is the base and height of the parallelogram? (3) What are the characteristics of the sides of a parallelogram? (4) What other graphics have we seen in our life? Through this design, it not only helps them clear their minds and grasp the key points of teaching, but also consolidates new knowledge and strengthens their memory. More importantly, children can be encouraged to preview with questions and enter a new knowledge ladder in the next class, so as to cultivate their ability to summarize and make a transition and pave the way for the next class.

Second, epitaxial type.

Extension is a further exploration of what has been learned, which enables students to think deeply about problems on the basis of proficiency, learn more about and get in touch with new knowledge, and prepare for broadening their knowledge horizons and cultivating their ability to draw inferences from others.

For example, when teaching Statistics, through study and observation, we already know how to count the temperature and the state of each classmate's home computer. So, what else can you be? The children are all pale. At this time, I reminded them to think about what you need to count in our lives. After class, you can learn about our living space and see the population and natural environment of our country, which are all important factors that affect our living space. You can surf the Internet or go to the library to find information, and I'll tell you what you learned in class tomorrow. Ending in this way not only consolidates the statistical knowledge they have learned, but also broadens their thinking, expands their cognitive field, enables them to find resources in their lives, and cultivates their observation ability and observation ability.

Third, the fun game style.

When it comes to games, children get excited because games are their favorite. If games are used in class, students' excitement will be aroused. It is also our usual method to intersperse games in class, but it is not common to set games at the end. Therefore, I try to use games to relax the children's body and mind, keep their strong interest, and end the new lesson with great interest.

For example, when I finished learning the Rules of Finding, I designed a game to find hats and scarves. I asked the students to divide into groups of three and let them take off their hats and scarves. Then let them choose how many ways to wear them. If they dress neatly and answer correctly, they can go out to play. The children got excited immediately after hearing this. They have to try it on again and again before they know how to match it. In such a happy time,

Fourth, the problem heuristic.

At the end of a class, we can leave some enlightening and interesting questions for students to think and verify in their spare time without any explanation, thus arousing suspense, stimulating their desire to explore knowledge and cultivating children's love for mathematics from an early age.

For example, after learning the application of percentage, I designed this question: Do you know what tax is? Who and units in China need to pay taxes? What is the tax revenue of our country used for? Through these questions, children can understand the situation in our country and know that mathematics is closely related to life. This conclusion not only consolidates the learning content of this class and even this stage, but also allows children to closely combine mathematics with practical problems and major current events in real life, avoiding single boring learning and helping to cultivate children's divergent thinking ability in analyzing problems.

Verb (abbreviation of verb) music appreciation style

Many people like music, but children prefer this atmosphere. They like singing, playing and dancing. Anything interesting can attract them. If you play some music, fairy tales and stories related to what you have learned, or watch videos, listen to children's songs and recite poems, children will be happy to learn. Let them feel the beauty of harmony and unity between mathematics and music in music.

For example, after learning Parentheses, I designed this ending: Today we met a new friend, Parentheses. Let's listen to music together. Pay attention to the lyrics! Then I played this song: brackets, very useful, count first when you encounter problems; Open your eyes to see clearly, but don't forget it carelessly; We have never been careless since childhood, and everyone is the best. The children listened to the song and sang along. They understand the role of scaffolding in happy singing, feel the beauty of music, really learn in entertainment and learn new knowledge in learning.

In short, in math class, we should pay attention to the end of a class. A good ending will make children unforgettable; It also helps children to learn after class and continue to discover and think about mathematics. Therefore, we should carefully design the end of each class, try to be concise, flexible, fresh and interesting, so that children can truly feel the infinite effect of the class.
