Sixth grade mathematics has little to do with seventh grade. Mathematics in Grade Six has little to do with Grade One. Many knowledge of Grade Six is rarely used in junior high school, such as positive and negative ratio, scale and cylindrical cone. If someone asks you to make up the sixth grade class, it must be a lie. Mathematics in senior one is very important, so we should lay a good foundation for mathematics in senior one and senior two. Mathematics in the first volume of senior one is mainly based on calculation, which requires training in the calculation of rational numbers, the addition and subtraction of algebraic expressions and the linear equation of one yuan, regardless of application problems.

Mathematics in the first grade of junior high school is very important.

Mathematics in the second volume of the first grade should also be calculated well, such as binary linear equations and inequality groups. These two application problems are more important and need proper practice. The parallel lines in the second volume of Grade One are more important, which is the basis of geometry and lays the foundation for the crucial triangle in the first volume of Grade Two. The plane rectangular coordinate system in the second volume of senior one is also very important, which is the basis of learning function.
