In the second grade, my children always fail in math, especially in application problems, and don't know how to speak them.
Hello, you can try: the high abstraction of content is the characteristic of mathematics, but it has a transition from lower grade to higher grade, and it is a process from concrete, vivid and intuitive to abstract logical thinking. In the second grade of primary school, thinking is not up to a high level, so when you talk to him, try to make your explanation close to life and his existing life experience, so that he can understand it easily, and then gradually deepen it, so that he can use deduction and experience.
