With the progress of science and technology, computer, Internet and other information technologies have become an indispensable part of people's daily life. Therefore, computer application ability has become one of the basic qualities that primary school students must have today. So, how to choose the right primary school mathematics textbook?

First of all, we should consider the age characteristics of primary school students. According to the age characteristics of primary school students, we can choose mathematics textbooks suitable for different age groups. For example, children under the age of 6 can use the children's mathematics textbook "I can speak numbers"; Children aged 7-8 can use the primary school mathematics textbook "I can calculate"; Children aged 9- 10 can use the intermediate mathematics textbook "I can think".

Secondly, we should consider the cognitive level of primary school students. According to the cognitive level of primary school students, we can choose suitable mathematics textbooks of different levels. For example, for primary school students with low cognitive level, you can use the children's mathematics textbook "I can speak numbers"; For primary school students with average cognitive level, you can use the primary school mathematics textbook "I can calculate"; For pupils with higher cognitive level, I can use the intermediate mathematics textbook "I can think".

Thirdly, we should take into account the ability level of primary school students to deal with different topics at different stages. For example, when dealing with graphics, geometric figures, time, weight, length, area, volume, speed, addition, subtraction, multiplication and division, fractions, equations, factorization, molecular formulas, true fractions, algebra and other disciplines, it is necessary to have corresponding ability levels. Therefore, when choosing digital textbooks for primary school students, we must choose them according to the ability level that children need to deal with different topics at different stages.

Finally, we should consider the family's ability level, including the area where the family is located, the money it can afford, whether it can get the corresponding teachers, whether it can get the corresponding time and whether it can get the corresponding venue.
