Whether the first-grade children need remedial classes depends on their personal situation and parents' opinions. In fact, the mathematics in the first grade seems simple. In fact, for children who have just entered the first grade from the relaxed and lively environment of kindergarten, mathematics in the first grade is not simple. They may know that one plus one equals two, but they don't understand why many children can't adapt to the relatively serious learning atmosphere in primary schools. That's what my children do. They have just entered primary school and just passed their first math exam. I am also surprised that my children have achieved such results, because my children have always performed well in school. Later, I sent my children to Zhuo Yue Wandie Education, that is, Zhuo Yue's branch school in Shenzhen University, only to know that teachers in general schools usually teach their children relevant knowledge through preaching and practice, but in fact, many children can't fully understand what the teacher said. Excellent teachers use the scene teaching mode to impart knowledge, that is, pay more attention to the balanced development of children's brains. For example, when talking about the knowledge point of "time", the teacher will not only tell the children how to calculate the time, but also let the children perceive the length of time through games, learn to cherish the time, and let the students plan their own time through manual creation and design, so that the children can "know why, know why". Now the children have been going to cram school for more than a month, and the progress is quite obvious. I am going to continue to send my children in the winter vacation.
