At present, some primary school math problems are abstract, which is difficult for primary school students to understand, and it is really difficult to master because of lack of interest in mathematics. It is the best way to improve children's understanding ability and cultivate their interest in learning through image expression, for example, to let children understand and learn mathematics knowledge in the process of reading. I recommend some good extracurricular reading materials for you, such as primary school science and technology magazines. There is a column in the magazine called "Mathematical Brain". This column teaches children to solve math problems in the form of stories. Not only have general knowledge of mathematics, but also Olympic math problems, which are of great help to primary school students in learning mathematics. In short, it is much better for children to read more interesting extracurricular books or magazines than to buy a tutorial book just for the sake of doing problems.
