Pre-algebra

Pre-algebra is a common name for a course in middle school mathematics in the United States, usually taught in the 6th, 7th, 8th, or 9th grade.[1] The objective of it is to prepare students for the study of algebra. Usually, Algebra I is taught in the 8th or 9th grade.[2]

As an intermediate stage after arithmetic, pre-algebra helps students pass specific 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

[edit]

Subjects taught in a prealgebra course may include:

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

Prealgebra may also include subjects from statistics to identify probability and interpret data.

Proficiency in prealgebra is an indicator of college success. It can also be taught as a remedial course for college students.[5]
