Unconsciously, you have been with your children for a semester. Many children are studying in the senior grades. Because of the accelerated class, the content of the class was finished before they could react. Students preview the content of the next semester in advance during the holidays according to their own learning situation, so you don't have to study so hard when you start school. Here is an example of how to organize the contents of a book. In fact, thinking frame diagram is a very good method. Now our common mind map is a very good learning tool. Let's take the math content in the second volume of the fifth grade as an example:

1, geometry module

After children enter the senior grade, mathematics will gradually be divided into two modules, one is algebra and the other is geometry. Therefore, when choosing primary school students, I especially like to study geometry.

On the whole, the study of geometric system can be divided into plane geometry and solid geometry. Before the end of the fifth grade in autumn, children will be trained to master various models in plane geometry. When we arrive in Joan Hinton, we will focus on curve geometry and solid geometry. In particular, solid geometry is a popular test site in recent years, so we should focus on it.

2. Application problem module

Before the summer vacation of the fifth grade, students learn application problems mainly by combining real life and understanding, so some classic application problems are brought in by situations, such as chickens and rabbits in cages. The method of doing the problem is relatively fixed and easy to learn.

From the summer vacation of the fifth grade, children need to master hundreds of application problems based on scores, percentages and proportions. So in the summer vacation of grade five, I first learned the calculation of fractions, and then in the autumn, I learned fractions and engineering application problems. In the summer vacation of the fifth grade, I learned the proportion, and then I learned the proportion application problem in the winter vacation; But the problem of concentration is more difficult, so in the spring of grade five, we need to study the elementary arithmetic of fractions again, and then talk about the application of concentration; As for the economy, put it in the autumn of the sixth grade. In this way, the application problem module in the primary school stage is almost completed!

3. Travel issues

Travel problems, from shallow to deep, have come into contact with the most basic travel problems, such as distance, speed and time, pursuit and encounter. The other is the formula travel problem. Before the fifth grade, we learned how to cross a bridge by train, run a boat and run a circular runway. In autumn, it is a little difficult for top classes to learn elevators and start. In the cold season, we will learn the last one, that is, the clock problem, which is very interesting as an extension of the circular runway. In spring, we will learn the proportional method to solve the trip. This part is a very selective module, of course it will be a bit difficult. In the spring course, learn the proportional method to solve trips (1) and (2). But this is only the foundation, and real learning will take place in the sixth grade.

4. number theory

The number theory module is divided into divisible number theory and remainder number theory. The number theory of divisibility We learned the characteristics of divisibility before the summer vacation of grade five. During the summer vacation, I learned the advanced and simple method of finding the least common multiple by doubling a large number.
