Pre-algebra is a common name for a course in middle school mathematics. In the United States, pre-algebra is usually taught in the 7th grade or 8th grade.[1] The objective of it is to prepare students for the study of algebra. Usually algebra is taught in the 8th and 9th grade.[2]

As an intermediate stage after arithmetic, pre-algebra helps students pass certain conceptual barriers. Students are introduced to the idea that an equals sign, rather than just being the answer to a question as in basic arithmetic, means that two sides are equivalent, and can be manipulated together. They also learn how numbers, variables, and words can be used in the same ways.[3]


Subjects taught in a Pre-algebra course may include:

Pre-algebra may include subjects from geometry, especially to further the understanding of algebra in applications to area and volume.

Pre-Algebra may also include subjects from statistics to identify probability and interpret data.

Proficiency in pre-algebra has been shown to be an indicator of college success. It can also be taught as a remedial course for college students.[5]
