The third grade is a watershed. At this age, children begin to enter the second half of primary school, and the learning tasks and challenges they face are different from those of the previous stage. They need more study and thinking, as well as more self-management and self-reflection ability.

Therefore, the third grade is considered as an important node for primary school students to learn. In terms of Chinese, third-grade students need to master more vocabulary and grammar knowledge, start learning writing skills such as diary and composition, and gradually enter the stage of extracurricular reading. In mathematics, junior three students need to master four operations of addition, subtraction, multiplication and division and their applications, and learn geometric figures and simple statistical knowledge. In addition, the third grade is an important period for students to develop oral expression, emotional management and social skills.

Therefore, both parents and teachers need to pay attention to children's learning and development characteristics in this important period, adjust educational strategies and methods in time, help children develop the habit of autonomous learning and management, and cultivate comprehensive quality. At the same time, we should pay attention to children's emotional health and social learning development to ensure their physical and mental health.
