Does primary school mathematics affect junior high school mathematics?
Influence! Especially in high school mathematics, most of the knowledge such as equations, fractions and symmetry are related to junior high school mathematics. It's just that primary school mathematics pays attention to simple knowledge, and junior high school mathematics goes deeper. Senior primary school students' computing ability, mathematical understanding ability and sense of number need to be cultivated, which is the basis of junior high school learning. A lot of knowledge in the seventh grade is deepened on the basis of primary school knowledge. With special emphasis on the use of calculators, students can learn to use them, but they must not be persistent in using them, which is easy to cultivate inertia, and the cultivation of arithmetic and number sense will be gone.
