How to preview mathematics in grade three
First of all, tell students the significance of preview and form a good preview consciousness. After studying in the first two academic years, the students in Grade Three have opened a big or small gap in their studies. Corresponding to students' personality differences, students' preview before class is also a very individual behavior. Those with strong understanding and acceptance may spend less time, while those with weak understanding and acceptance can spend more time thinking carefully to make up for the lack of class time. If the preview is really fully developed, students will have a roughly equivalent re-learning foundation, so they will certainly get several times better grades in class than students who have not previewed. Second, guide students to preview and achieve higher preview efficiency 1. Read this book. Grade three students can try to read independently after class. "Take a look" is to let students know what they want to learn in advance, have a general learning direction, not blindly attend class, and reduce the preparation time for entering the learning role in class. 2. Make a book. The new textbook no longer presents knowledge directly to students, but leaves a lot of blanks, which should be done by students themselves. For example, if you preview the position and direction, you should pay attention to the practical characteristics of this unit. Preview should not only stay in books, but also focus on practice. "Doing" here should mean "doing math", not just "doing homework". Do a good job of teaching materials in advance, and you can also check the effect of "taking a look". After such full preview and entering the classroom, everyone's study is highly targeted. Even if sometimes teachers don't anticipate problems, they can solve them by asking questions, thus making their classroom learning more efficient. 3. "Say" this book. After completing the requirements of "seeing" and "doing", students will be divided into two camps: one is the camp with problems and the other is the camp that can solve problems (of course, these two camps are dynamic and inclusive). At this time, teachers should really become the organizers of classroom learning and guide students to solve problems by themselves, as required by the new curriculum. The so-called "talk" here has actually closely linked pre-class preparation with in-class learning. What I want to mention here is that the expression of mathematics cannot be separated from the language of mathematics. The language of primary school mathematics is still close to the daily language. But mathematical language is more precise and concise than everyday language. Remind students to pay attention to this when "speaking". For example, when analyzing practical problems, refine everyday language into more refined mathematical language. Third, implement the students' preview plan and develop good preview habits. First, make clear the task of preview before class. The content of preview can be both new knowledge to be learned and old knowledge related to the content to be learned. In particular, we should remind students of some important links between old and new knowledge. The requirement of preview before class is to "read" books, "do" books, and then "speak" in class. Then check the preview a few minutes before class or a few minutes before class. See if there are any signs of "reading" and "doing" in the textbook. Through the actual reflection of "speaking" in class, encourage those students who really preview carefully in time, so as to move everyone to preview more seriously. In addition, after class, students with unsatisfactory preview situation are given timely and targeted individual guidance, so as to correct preview ideas, consolidate preview methods and urge preview behavior. If we persist in this way, when all students develop good preview habits, the learning efficiency in the classroom will be greatly improved. It is not only completely feasible but also necessary to guide students to preview actively from the third grade. Personalized learning begins with personalized preview. When they really master this learning method, they will gain the ability of "lifelong learning".
