That is, preview with a clear preview task.

For junior children, preview is a great difficulty, and beginners often don't know where to start. At this time, it is an effective preview method for teachers to design preview tasks in advance and let students preview with tasks.

This method is highly targeted, which can help children with unclear ideas find the right direction quickly, but at the same time, it also requires teachers to carefully study the relevant learning content. The questions raised are both valuable and attractive, with moderate difficulty, strong inducement and interest, clear requirements and strong operability.

Method 2: Note preview method

1, comments

After browsing the content of this lesson, students can write down their views and opinions on the text in the blank space.

Step 2 extract notes

After preview, students can extract the key contents and key words of this section in their notebooks, which is helpful to deepen their memory and understanding of new knowledge.

Of course, students can also record the difficult parts in the preview process. When studying formally, ask questions to the teacher in class, solve your doubts as soon as possible, or write down your gains from the preliminary preview.

Step 3 reflect on notes

For some students with good foundation, in addition to the above basic requirements, they should also learn to take reflective preview notes as much as possible to improve their thinking ability. For example, when doing application problems, I always forget to convert units, which leads to wrong results and needs to be corrected.

Method 3: Review old knowledge and learn new preview methods.

This is a preview method to link old and new knowledge.

In the preview, on the one hand, we can learn new knowledge, sum up key points and find problems; On the other hand, review and consolidate the old knowledge associated with the new knowledge. Link new content with old knowledge to systematize knowledge.

Method 4: Try to practice the preview method.

The biggest difference between the study of mathematics and other disciplines is that students are required to use mathematical knowledge flexibly to solve problems. After students have a preliminary understanding and mastery of new knowledge through their own efforts, they should also test the effect of their preview through practice, which is an indispensable process of mathematics preview.

Method 5: hands-on preview method

For some operational knowledge, students are required to practice by themselves in the preview process, and experience and feel new knowledge through activities such as cutting, spelling, folding, moving, putting, drawing, testing, observing and comparing. Only when students have experienced the formation of mathematical knowledge can they know why.

Method 6: cooperative preview method

Students can learn, compare and communicate with each other. The cooperative division of labor in the preview process can help you complete the preview task from different angles. This way can help students form the spirit of unity and cooperation, and from a personal point of view, it can also improve students' problem-solving ability.

Method is an important strategy to solve problems. Mathematics is full of surprises. Not previewing is like standing in front of a house full of treasures, but you can't find a way to get in. Mastering the method of learning is like mastering the "golden key" to open the treasure house of knowledge.

There are many ways to preview mathematics. According to the characteristics of primary school mathematics textbooks and the learning ability and habits of primary school students, different preview methods can be adopted to help children master knowledge.
