Actually, it's not necessary Chinese mathematics in primary schools is very basic and teaching is very slow. If children are forced to study ahead of time, they may get tired of learning. The gain is outweighed by the loss. Parents can instill something in their lives, such as taking their children to teach him simple addition and subtraction when buying food, so that he can be interested. However, he can read newspapers and cultivate the habit of looking up a dictionary. Good study habits are more important than knowledge! I wish your children a happy study!
