us high school age
Seventh grade (called Grade 7 in some regions) is a year of education in the United States and many other nations. The seventh grade is the seventh school year after kindergarten. Students are usually 11–13 years old. Traditionally, seventh grade was the next-to-last year of elementary school. In the United States it is usually the second year of middle school, the first year of junior high school or the 7th year of elementary school.
In the United States, in mathematics, students focus commonly on an introduction to pre-algebra or the beginnings of algebra, including ratio, proportion, percent. New topics sometimes include scientific notation, concepts with negative numbers, and more advanced geometry. In some parts of the United States, such as Colorado and California, math may be mixed-grade according to the student’s previous knowledge, so some students may already be in a 9th grade algebra course. In social studies, advanced pre-Civil War History is taught. Though American history is usually the norm, other cultures may be taught. In science, it is usually moderate-level biology. In some parts of the United States, seventh grade is the first school year in which students have different teachers for each of their subjects, and so they change classrooms at the end of each period.
