How to learn primary school mathematics well;

Play more digital games. There are many games about numbers. We can play some games with children, such as Sudoku, 2048 and so on. Through these games, children's digital sensitivity can be improved.

Education through fun is very effective. Any boring education is a failure. If children can't get pleasure from learning, they won't always be interested in mathematics, or even hate it gradually, so they can't learn well.

Parents follow up the learning progress. Parents must know the progress of their children's math study. If they don't know, they can't give proper counseling in time. If you don't pay attention to tutoring your child at ordinary times, your child may gradually fall behind in the course.

Assist some knowledge of Olympic mathematics. Olympic Mathematics is a very effective course. Although we don't advocate organizing Olympic math competitions or learning too deeply, Olympic math, as an interesting mathematics, attracts children's interest in learning.

Practice math exercises more. If math is really bad, you can let your children do more problems. By doing various types of exercises and papers, children can understand the problem-solving ideas of various types of questions, so as to learn mathematics well.
