Especially the children in grade one have just laid a good foundation, which is the primary stage of the formation of mathematical thinking. If they don't learn well now, it may be difficult to cultivate systematic mathematical thinking, which is not conducive to the development of children's comprehensive ability and the improvement of their learning ability in the future. My daughter is nine years old this year. When she first entered primary school, she didn't learn math well. A friend recommended a cram school for mathematics in normal education. After studying for a semester, her final exam results came up. She can think independently and draw inferences from others. Now she can basically finish her homework by herself without our help. Very worry-free.
