1. For children who have just entered school, studying hard and doing their homework seriously does not mean that they can think. Children get good grades in grades one and two, mainly because there are many memories and imitations in the learning content of grades one and two, and children rely on mechanical memory to copy. You can also get good grades. However, from the third grade, even in the learning content that needs rote memorization and imitation, there are a lot of factors that need children's brains. For example, children do not pay attention to this, or learn by mechanical memory. Then, with more and more brain factors and the deepening of learning content, children's academic performance will gradually decline.

2. In the third and fourth grades of primary school, children's learning gradually changed from passive to active, and began to pay attention to the results of learning. In addition, their knowledge and interest are expanding day by day, and they begin to be interested in the causal relationship and calculation law between nature and society. They want to run a business and like to raise small animals. With the accumulation of knowledge and experience, their abstract thinking began to develop and their reading scope began to expand. Due to the deepening of learning, their acceptance ability has been improved, but at the same time there have been obvious differences and learning differentiation.

3. When the child is in the first grade or the second grade, parents and teachers follow closely and strictly manage the child in all aspects. However, after the child enters the third grade, parents and teachers may feel that the child has adapted to school life and is not as worried as before. In addition, children's self-control ability is not strong and they are prone to differentiation.

Therefore, although children's grades in the first and second grades of primary school are almost the same, some children have a solid foundation and some children have a weak foundation. Because the learning content of grades one and two is relatively simple, there will be no obvious difference. However, after entering the third and fourth grades, children with poor foundation will find it hard to study, and their grades will naturally drop significantly, which will also lead to weariness, decreased self-confidence, weak self-motivation and inferiority. Therefore, the grades of the first and second grades of primary schools need to be taken seriously, but they don't need to be taken seriously, because the grades in this period are deceptive to some extent. During this period, the most important thing for parents is to cultivate their children's good study habits and behavior habits, protect their children's freshness and interest in learning, pay attention to their basic development, ability and habit cultivation, and truly get twice the result with half the effort, so that children can benefit for life!
