Mathematics, the foundation is very important. Although the child is in the fifth grade, have you mastered the knowledge before the fifth grade, especially the calculation ability, which is the basis of mathematics. Starting from the calculation, it should not be too late. If children have good computing skills, their math scores will naturally improve, while one-on-one tutoring and small classes have their own advantages. One-on-one tutoring will be more targeted, and the atmosphere will be better if you teach in small classes, and you can also learn from your classmates. My child was originally enrolled in a small class taught by Mr. Ming, and the classroom atmosphere was very strong. Children can stimulate their interest in learning in this competitive environment. Later, the child gradually formed the idea of doing the problem, and after the basic knowledge was solid. I gave him one-on-one tutoring in winter vacation because he was weak in area calculation and equation calculation. One-on-one can be targeted to check leaks and fill gaps, and break through difficulties.
