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]
