Pre-algebra

[1] The main objective of it is to prepare students for the study of algebra.

[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.

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